Unilos autonomous sewerage device. Autonomous sewage system Unilos: principle of operation, installation

Treatment stations are the easiest way to provide yourself with the same level of comfort in a country house as in a city apartment. Septic tank Astra Unilos is innovative drainage well, which purifies wastewater using an aerobic bacteria.

Septic tank Unilos Astra is an autonomous water purification system, which is designed for various quantities living in the house (depending on the model, this is 5 for five family members, or 8 for eight, respectively). A bioseptic is considered safer to use than a classic mechanical sump tank, since it does not cause any harm to the environment and is characterized by cleaning efficiency. Its analogues are the developments of the company Unilos Scarab and Cyclone, Topas from the Topol and Yubas plant.

The bioseptic tank is designed using an all-in system, i.e., all compartments are located in one container - the main tank. This tank is divided into several sections: a receiver, an aerobic chamber or aeration tank, a settling tank and a sludge receiver. Each is connected to the previous one, but thanks to the special design of the filters and the presence of a compressor, water cannot flow into the previous one. Due to the pump, technology with forced drainage of wastewater is used, which significantly speeds up the process of operation of the entire system.

Advantages of the system:

1. The device guarantees fully automatic wastewater treatment with high efficiency. According to recent studies, the efficiency is up to 99%, which is almost twice as high as that of systems with a mechanical operating principle;
2. Simple installation on site;
3. Energy saving. The consumption of a septic tank can be compared to the electricity costs of operating a washing machine;
4. The special design of the tanks prevents gas leaks and unpleasant odors. This is especially important if the septic tank is installed in a residential yard country house or at the dacha;
5. Technical resistance to mechanical and chemical influences. In addition, spare parts do not respond to sudden temperature changes characteristic of the Russian climate;
6. The compressor installed in the treatment tank ensures high pumping speed clean water and treatment of contaminated wastewater. When using traditional settling tanks, sewerage is cleaned within 3 days.

But the Astra septic tank also has its own flaws:

1. Expensive maintenance. The main filter used to treat water is anaerobic bacteria. They need to be updated every year, otherwise the system will be ineffective;
2. Repair and maintenance are very difficult to do with your own hands;
3. High cost of the system;
4. Due to the presence of living microorganisms, so that they do not die in winter, the septic tank requires additional insulation;
5. With intensive use, regular malfunctions of aerobic tubes and filters are possible.

If we compare mechanical and natural options cleaning with biological, then there will be no doubt. The biosystem is based on completely natural processes, where microorganisms that are safe for humans clean wastewater from odor and solid particles and saturate it useful substances. In addition, the work scheme provides for the presence of toilet paper and other hygiene products, and does not clog even with a large number of them.

Principle of operation

Regardless of the modification (midi, max and others), the effect of the Astra septic tank does not change. Sewage from the sewer enters the first receiving compartment, where its primary purification is carried out; due to gravitational force, it is freed from solid particles and cleaned with a post-treatment filter. Also here the wastewater settles for some time.

Afterwards, the water is forcibly pumped into the next chamber – the aeration tank. Here is the most important filter systems – bacterial. The manufacturer made sure that at this stage the liquid is not only cleaned of harmful particles, but also additionally saturated with oxygen. This eliminates unpleasant odors and improves water quality.

The next chamber sifts out the sludge. The fact is that different sludge has different weights, so it can literally reach the final stage of wastewater treatment without any changes. But the unique operating system of the Astra septic tank filters even the smallest particles and, if present, forcibly transports them to the previous bacteriological compartment.

The last chamber is the final cleaning filter. There are several cleaning mechanisms installed here that filter the wastewater. Using a pump, clean water is transported to a certain place or for watering plants as technical water.

Installation of a septic tank

Installation treatment system Astra can be made with your own hands; the principle of connecting a septic tank to a sewer system is practically no different from connecting a septic tank made of rings to it.

Step-by-step instruction:

1. Before the beginning installation work you need to prepare the area. For a summer residence or residential cottages The minimum permissible distance for installing a septic tank is 6 meters from the facade of the building. Please note that if there is a water source on or near the site, then the distance from it should be approximately 50 meters;
2. The depth of digging depends on the level of soil freezing. The wall thickness of 2 centimeters is beyond doubt mechanical strength, but plastic becomes brittle when exposed to low temperatures, so it's better to play it safe. The container must be completely immersed in the pit, the trench is additionally concreted and insulated;
3. To insulate the pit, a variety of materials are used: clay, polystyrene foam, penoplex and other available heat insulators;
4. Before concreting, branches are excavated in the ground to the house and other sewer outlets(for example, to summer soul or bath);
5. Installation of the septic tank itself is carried out only with the help of special lifting equipment; the weight of the system exceeds 500 kilograms;
6. After installation, all pipes are connected to the septic tank, and the joints are sealed.

The operating instructions for the Astra septic tank are very simple: periodically clean the settling tanks of sludge and dirt and replace the bacterial filters. Some experts say that there is no need to renew bacteria, because they multiply on their own in the septic tank, but we still recommend periodically checking the effectiveness of the aerobic filter.

In my article I am going to introduce the reader to the Unilos company and its products, in particular to local wastewater treatment plants. We have to study the principle of their operation, design, prices and examine several samples from different price categories. Let's get started.

Manufacturer

Products under the Unilos brand are produced by the Russian company SBM-Group. All products are manufactured according to full cycle, without ordering components from other manufacturers.

The company's representative offices are located in several major cities Russia (Moscow, St. Petersburg, Sochi, Yaroslavl, Novosibirsk) and abroad - in Kazakhstan (Alma-Ata) and Azerbaijan (Baku).

Septic tanks and other company products are supplied by the manufacturer and numerous dealers throughout Russia and exported to neighboring countries.

Stand of the company's products at the Oil and Gas 2014 exhibition.

Range

The list of products under the Unilos brand includes:

• Non-volatile septic tanks;
• Containers for sewage and fecal water (they are not quite accurately called storage septic tanks) and for water;
• Grease traps for drains;
• SPS for forced pumping of domestic and industrial wastewater;

• Deep biological wastewater treatment stations for private and apartment buildings.

Theory

Operating principle

First, let's figure out what sewage treatment technology is used in septic tanks and other VOCs (local treatment plants).

The most structurally simple single-chamber septic tank works like this:

1. The wastewater ends up in a large sedimentation tank, where it spends several days. During this time, they settle: heavy sludge settles to the bottom, where it is gradually processed by anaerobic bacteria; lighter feces, grease, paper and other organic waste form a dense fermenting crust on the surface. Relatively clean water remains in the middle of the container;

For the settling tank to function, the incoming flow must not mix its contents throughout the entire volume.

1. Through a specially shaped overflow, which collects water below the crust, the water enters the soil for post-treatment (in other words, it is absorbed into the soil in the filter bed or on the filtration field).

The photo shows an overflow and a filter well.

As an overflow in homemade septic tanks, a regular sewer tee in a vertical position is used. The lower outlet is used for water selection, the upper one is for cleaning, the middle one is for draining wastewater from the sump.

Solids accumulate in the settling tank and it requires periodic cleaning. However, it is only needed once every one or two years, since household wastewater consists of 98 - 99% water.

Calculations

For a septic tank to work, the volume of its sump must be equal to or exceed the three-day volume of wastewater (with a daily flow rate of more than 15 m3 - the volume of wastewater for 2.5 days). During this time, the wastewater undergoes complete gravitational separation: everything that can sink sinks, everything that can float floats.

Calculating the daily volume of wastewater is extremely simple: it corresponds with changes in water meter readings with a minimum error. The exception is the situation when water is used for irrigation. Then it’s easier to focus on sanitary standards - 220 liters per person per day.

For a filter well or filtration field (drainage laid in the ground), the absorbent surface area is important. It is determined both by the flow of wastewater and the absorbency of the soil. Here are the values ​​of the latter for different soils:

Efficiency is everything

The quality of wastewater treatment for a properly designed single-chamber septic tank is 70-80%. Simply put, 1/3 - 1/5 of the pollution remains in the settled water and, frankly speaking, does not ozonize the air.

Luckily, there are a number of ways to improve your cleaning experience.

Here they are:

• Increasing the number of sedimentation tanks connected in series by overflows;
• Aeration of sedimentation tanks. The rapid proliferation of aerobic bacteria leads to a decrease in the amount of pollution in wastewater: all organic matter serves as food for the fauna of the septic tank;

• Biofilters are flow-through compartments filled with plastic brushes or other material with large area surfaces. Organic-eating bacteria again multiply when loading the biofilter.

Practice

Here's how the Kedr septic tank from Unilos works:

1. The wastewater flows by gravity into the first settling chamber. It separates into the silt remaining at the bottom, the surface crust and relatively clean water;
2. In the second chamber, the water is clarified during the process of settling and the activity of anaerobic bacteria;
3. In the third chamber, the water passes through a biofilter (the notorious plastic brushes), where the surviving remains of organic matter are eaten by aerobic bacteria;
4. In the fourth and last chamber, the water is finally clarified. A drainage pump is also installed in it (in the event that treated wastewater needs to be raised to ground level).

Unilos Astra deep cleaning stations complete the cycle:

• Aeration of wastewater;
• Recirculation of activated sludge between settling tanks (this allows accelerating the biological processing of organic matter by bacterial colonies);
• Aerobic stabilization of sludge accumulating in the settling tank. Simply put, when air is blown through it, bacteria eat up the remaining organic compounds and die from lack of food.

In the future, I am going to pay close attention to the VOC Astra line as the most interesting for potential consumers. Gravity septic tanks from Unilos are structurally practically no different from products from other manufacturers and from home-made structures.

What does this VOC operation scheme provide?

Autonomous sewage system Unilos Astra provides a purification rate of 95%. The output water is completely odorless. Of course, you shouldn’t use it as drinking water, but using it for watering an area or simply dumping it on the terrain is quite acceptable.

In addition, the operating principle of an autonomous sewage system for a private house with wastewater aeration and biofilters ensures that solid sediment is odorless. The sludge can be removed from the VOC compartment by a drainage pump and used as fertilizer.

How profitable is it to install Unilos Astra?

Here is the calculation of overhead costs for a storage septic tank (read: a sealed cesspool) in 2016 prices relevant for Crimea:

• With appropriate sanitary standards water consumption of 220 liters per person, a family of 5 people will spend 1100 liters per day, or 401 cubic meters per year;
• Calling a sewage disposal truck with a tank volume of 4 cubic meters currently costs about 2,000 rubles (with a slight variation depending on the company offering the service);

• Over the course of a year, in an ideal case (that is, if the tank leaves filled to capacity), 401/4 = 100 (rounded down) calls for sewer trucks will be needed;
• They'll get by family budget in 100*2000=200000 rubles.

For comparison: a Unilos Astra 7 deep treatment station with a capacity of 1.4 cubic meters of wastewater per day costs 90,100 rubles. With the declared consumption of kilowatt-hours per day, electricity consumption for the year will be 365 kWh. The price of a kilowatt-hour of 4 rubles gives us a total cost of 1,460 rubles.

Installation

What does the installation of Unilos Astra or any other deep wastewater treatment plant look like?

The instructions were kindly posted by SBM-Group on one of the sites dedicated to their products.

1. At the site of the future location of the VOC, a pit is opened, the dimensions slightly exceeding the size of the station (for example, for Astra 5 with its size of 1120x1120x2360 mm, a pit of 1.5x1.5x2.3 meters is needed);

Unlike traditional septic tanks, a deep cleaning station can be installed on minimum distance from the house (in particular, right next to the blind area).

1. The bottom of the pit is covered with a 10-centimeter layer of sand. It allows you to level the bottom and prevents frost heaving of the soil, performing the function of drainage for groundwater;
2. The Unilos station is placed on the pillow. The dimensions and weight of VOCs up to Astra 7 (productivity 1.4 cubic meters per day) allow them to be installed manually. For more massive and productive septic tanks, loading equipment will have to be used;

1. A trench is opened from the house to the pit, into which sewer pipes with a diameter of 110 mm and a power cable are laid with a slope of 2 cm per linear meter;

The sewerage system is installed below the soil freezing level. Where this is not possible, the pipes are thermally insulated and supplied with a heating cable.

1. The sewer is connected to the VOC filler pipe;
2. The body is filled with sand (again serving as drainage for groundwater). The station is ready for operation.

Questions and answers

Are there any restrictions associated with the operation of VOCs and Unilos septic tanks?

Forbidden:

• Dispose of rotten vegetables, sand, construction and household waste into the sewer;
• Dispose of potassium permanganate and other oxidizing agents and antiseptics (including chlorine and oxygen-containing laundry bleaches in large quantities);
• Merge rinsing waters from pool filters;
• Pour solvents, fuels and lubricants, antifreeze, alkalis, acids, alcohol and other liquids into the toilet that can destroy bacterial colonies in the biofilters of a septic tank.

How will a power outage affect the work of the Unilos station??

If you turn off for up to 4 hours, no way. If there is a longer power outage, the primary settling tank may overflow due to the pump stopping. As a result, untreated water may be discharged.

In addition, when aeration is stopped, unpleasant odors may appear due to a slowdown in the vital processes of aerobic bacteria.

Comrade! The lights have gone out - turn off the water!

What kind of maintenance does the Unilos Astra station need?

Once a week, visual control of the quality of cleaning is desirable. To do this, just open the VOC cover and look into the last compartment. The water should be clear and odorless.

Once every three months you need:

• Cleaning the sedimentation tank from sludge using a standard pump (the so-called mamut pump);

You can use any other fecal drainage pump with the same success.

• Cleaning the pump itself and the inlet filter, designed to retain large impurities and foreign objects;
• Cleaning the walls of the second compartment of the settling tank;
• Cleaning aerator filters.

Once every six months you need to clean the hair filter located in the section with the aerator.

How long do Unilos stations last??

• Body plastic - at least 50 years;
• Aerator - 10 years;
• Compressor - 5-10 years.

Once every couple of years, the compressor needs to preventively replace the membrane responsible for pumping air.

Is it necessary to pump out wastewater from VOC settling tanks for equipment maintenance?

No. For free access to any serviced units, simply fold back the cover.

Does Unilos Astra need additional insulation in a cold climate zone?

During work - no. Its body is made of foamed polypropylene, providing high-quality thermal insulation. In addition, the vital activity of aerobic bacteria releases a fairly large amount of heat, which maintains a positive temperature inside the VOC.

If there is no sewage flow for a long time during the cold season (for example, if you are not going to visit the Vacation home) VOCs are preserved:

• Part of the water is pumped out from the aeration and stabilization compartments;
• The lid is insulated with foam plastic or other material with low hygroscopicity.

When VOCs are put into operation, a volume of water sufficient to fill the stabilizer and aeration tank is drained through the sewer.

Study of samples

Towards the end, the reader and I will have to study several deep cleaning stations and one Unilos septic tank - their prices, sizes, performance and other characteristics.

Retail prices vary markedly depending on the region of the country (and, accordingly, the cost of delivering equipment) and on... let's say, the immodesty of the seller. The same Kedr is offered by a certain Moscow company for 79,900 rubles. Agree that the dealer markup of 30% is clearly too much.

Conclusion

I sincerely hope that my article will help the dear reader to choose optimal solution For own home. The video in this article will help you learn more about products under the Unilos brand. I look forward to your additions and comments to it. Good luck, comrades!

The Russian company SBM-group specializes in the production of closed-type septic tanks capable of processing sewage into safe process water without human intervention.

Series range of Astra closed-cycle sewerage treatment system

The number indicating the type of model is also an indicator of the number of residents that this capacity is designed to serve.

1. Astra 3. Compact: length – 1 m, height – 2.03 m, width – 0.8 m. Volume – 150 l, power – 0.6 m3. Available in two types: with a flat lid and a decorative one in the shape of a mushroom. Optimal for small country houses and guest houses.
2. Astra 5. Available in two types, differing in size and design: “long” and “midi”. Dimensions: length - 1.03-1.13 m, height - 2.6-3.13 m, width - 1 m. Septic tank Astra 5 is the most popular among owners of small and medium-sized private houses.
3. Septic tank Astra 8. Volume – 350 l, capacity – 1.6 m3. Suitable for a house designed for permanent residence of 8 people.
4. Astra 10. Large septic tank, which is difficult to install without the help of special equipment. Optimal for cottages and other properties with several bathrooms equipped with bathtubs. Designed for salvo discharge of up to 550 liters. Capacity 2 m3.
5. Septic tanks Astra 15-40 and 50-150 are designed for servicing a complex of buildings.

Septic tank installation

The body of the Astra Unilos septic tank is made of thick polypropylene, which does not pose an environmental hazard to environment. This material is resistant to chemicals and can withstand heavy weight loads. The body is equipped with stiffening ribs that form a single unit with the walls of the septic tank. monolithic structure.

Thanks to the 2 cm thickness of polypropylene, when installing the treatment structure, there is no need to concrete the bottom of the pit.

Septic tank compartments

The internal space of the cleaning device consists of several chambers, into which liquid is poured through an airlift system. The design of the septic tank does not include a single mechanical unit, which eliminates the possibility of breakdowns and equipment failure.

The principle of operation of the Unilos Astra septic tank: mechanical oxygen supply using a compressor (forced aeration) and independent biological treatment of wastewater.

1. Compartment No. 1 is a receiver for wastewater leaving the house. Here, clarification of sewage water occurs through settling and precipitation of large fractions. This camera has the largest size.
2. Compartment No. 2 is an aeration tank. Here colonies of biobacteria enter into the fight against organic compounds. To start the operation of this compartment, it is enough to add the required biological product once and there is no need to replenish it in the future. Bacteria reproduce on their own, but they need oxygen to function normally. For the supply of which, the design itself provides for purging, operating on the principle of intermittent aeration.
3. Compartment No. 3 is a secondary settling tank. Here, lighter fresh particles rise to the surface and are redirected again to compartment No. 2, and heavy old fractions settle in a special receiver, which is subject to periodic cleaning.
4. Compartment No. 4 is a settling tank in which wastewater is purified to process water. A drainage pump can be used to remove the liquid, and the water itself can be used to water the garden plot.

Treatment facilities of the Astra series are produced in 3 types, each of which differs from the other in design solutions: standard, midi and long.

• Astra standard is designed for an inlet pipe connection depth of at least 0.6 m from the soil surface;
• Astra Midi - not lower than 0.6-0.9 m;
• Astra Long - not lower than 0.9-1.2 m.

The structures are equipped with additional devices that facilitate the operation and maintenance of the station. This is a built-in sewerage pumping station and a post-treatment unit with a pump, an ultraviolet disinfectant and an ultrasonic cavitation unit.

Astra treatment plants are reliable and durable. The disadvantages include: dependence on electricity, fairly high cost, impossibility of installation at temperatures below 10°C.

Local sewerage for suburban areas has become an excellent opportunity to provide the usual comfort of living. Autonomous septic tank Unilos Astra effectively solves the problem of water disposal and wastewater treatment. A wide range of installations allows you to choose a treatment facility that matches the performance.

Design and principle of operation

The SBM-group company produces closed-type septic tanks that utilize and purify sewage into the state of industrial water. The unit body is made of durable propylene; the material does not corrode and can withstand high loads. The treatment station is located underground and does not take up space on the site.

The entire system is placed inside the housing, this ensures a compact design size and reduces heat loss. Technological welding makes the seams completely sealed, eliminating leaks. Water purified in a septic tank can be discharged into the ground, reservoir, or used for household needs; it is 98% free of impurities.

Attention. The design of the Astra septic tank has stiffening ribs that ensure the strength of the body and eliminate the need for additional concreting.

The internal space of the station is divided into four compartments:

• reception section;
• aeration chamber;
• sludge collection compartment;
• secondary settling tank.

Internal devices of Astra Unilos

How does a septic tank work?

The process of wastewater treatment combines the use of two methods of removing contaminants: mechanical and biological. Household waste flows by gravity into the receiving chamber, where it is settled and separated into fractions. A coarse filter is installed here to remove debris from the liquid. The clarified wastewater is pumped by airlift into the aeration tank. Cleavage occurs in this compartment organic matter aeration bacteria. A special membrane compressor saturates the water with oxygen, accelerating biological processes.

Purified water enters the section where coarse sludge is deposited, and fine suspended matter is returned to the second compartment of the station. The fourth section performs final filtration of wastewater. After this, the water leaves through a pipe system or is pumped out by an installed pump.

Attention. The operating mode of the treatment plant is adjusted automatically. Hiblow membrane compressors are installed as equipment.

Model range overview

Unilos septic tanks differ in performance, modifications and method of drainage. Each model has a digital designation showing the estimated number of residents of the house served. This indicator varies from 3 to 150. The most popular models are:

Astra 3

The compact and easy-to-install septic tank Astra 3 is suitable for a summer house or small house. The installation capacity is 600 liters per day, and the maximum discharge is 150 liters. Thanks to small size station (1.12x0.82x2.03m) and weighing 120 kg, it can be installed independently.

Astra 5

The best option for a family living in a private house would be the Astra 5 septic tank. The station's capacity is 1 m3, the salvo discharge is 250 liters. The thickness of the case walls is 20 mm, which guarantees reliability and tightness. When installing a treatment plant in an area with clay soil, it is equipped with a pump for forced drainage. If the depth of the main drain supply line is 60 cm, the standard model is selected. The presence of modifications allows you to use the Unilos Astra 5 septic tank when laying discharge pipes at a depth of 90 cm and below.

Installation dimensions:

• midi – 1.03×1.12×2.505 m (at a depth of 60-90 cm);
• long – 1.16x1x3.03 m (at a depth of 90-120 cm).

Astra 8

For big family or a combination of two neighboring plots, the Astra 8 septic tank, which can hold up to 1.6 m3 of wastewater, is suitable. The station is offered in three modifications:

• standard - with normal installation of the supply line at a level of 60 cm;
• long - for areas with a sewer pipe depth of 90-120 cm, in the presence of a high groundwater level, the installation is equipped with a container for collecting treated wastewater;
• midi - the structure is recommended for a system where the supply pipes are located at a depth of 60-90 cm.

The aeration structure is designed for a maximum one-time discharge of 350 liters. Its dimensions: 1.5 × 1.16 × 2.36 m. When installed in sandy soil drainage is carried out by gravity drainage ditch. The station on an area with clay soil is equipped with equipment for forced diversion.

Astra septic tank models

Unilos Astra septic tanks with high productivity up to 30 m3 are installed in hotels, villages, and administrative buildings. The stations are designed for the number of consumers up to 150 people. The presence of a reservoir for purified water allows you to avoid waterlogging the soil in the surrounding area.

Advice. When installing a septic tank, a sand cushion of up to 15 cm must be poured into the pit. The installation cover should be located 20 cm above ground level. This will prevent rainwater from entering.

Advantages and disadvantages

The advantages of the Unilos biological treatment station include:

1. Full automation of the process and high degree purification – 98%.
2. Low power consumption.
3. The robust design of the case and the use of high-quality material ensure safety of use and the absence of unpleasant odors.
4. The installation is designed for operation at low temperatures.
5. The cleaning station can operate all year round or be mothballed for the winter; after a seasonal downtime, it can easily resume operation.
6. The service life of a septic tank is up to 50 years; only the equipment needs scheduled replacement.

Disadvantages of the treatment plant

There are few disadvantages to a septic tank:

1. Energy dependence is the main disadvantage of the installation. When there is a power outage, it is necessary to reduce the amount of water drained as much as possible, otherwise the receiving section will overflow.
2. The high cost of the station is an obstacle to purchase for some buyers.
3. System maintenance and cleaning is required. Most You can do the work yourself; specialists are only needed to repair equipment.

Operation and Maintenance

After the first start-up of the treatment plant, maintenance of the Astra septic tank will be required after a year. During operation it will be necessary visual inspection condition of the equipment and the station itself. The service procedure includes the following items:

• Renewal of the colony of bacteria that bind nitrates. This will increase the efficiency of the aeration filter.
• Removing thick accumulated sludge. The sludge does not contain chemical components and can be used as fertilizer. The cleaning time is determined by a sample taken from the settling tank; if the sludge concentration exceeds 30%, pumping is necessary.
• Clean the system filters 1-2 times a year. The devices are removed and washed under water pressure.

Advice. Full maintenance of the installation must be performed every two years; it is better to entrust it to specialists.

IN sewer system it is forbidden to reset medications, polymer films, solvents, chlorine-containing products. These substances lead to the death of aerobic bacteria and deterioration in the quality of wastewater treatment.

Preservation for the winter

When using the station seasonally, it is necessary to properly preserve:

1. Disconnect the septic tank from power.
2. The water level should be 75% and topped up if necessary.
3. The sludge compartment is cleaned and washed.
4. The compressor is removed from the instrument compartment.
5. Plastic bottles are filled with sand and tied to the edge of the body, they are placed in the form of floats in each section. This will prevent the formation of an ice crust.
6. The cover of the installation is covered with insulation.

Insulating the station cover with penoplex

Nadezhda Ivanovna, 60 years old

It’s better to invest in sewerage once and use it without problems. I bought a Unilos Astra 5 septic tank and got rid of worries, maintenance is simple and is rarely done.

Dmitry, 35 years old

Don't forget to rate the article.

ABOUT One of the most modern and highly efficient systems for deep biological wastewater treatment is the Unilos Astra bioseptic tank. The sewage treatment rate is up to 98%, which even allows the treated wastewater to be reused, for example for watering plants and trees in the garden. The lineup septic tanks Unilos Astra is so wide that it allows you to choose suitable type biseptic tank for a small child country house for three people, and for a country hotel for 300 guests including staff. You can view all Unilos Astra models and compare them with other biological wastewater treatment stations on our website in the section OUR PRICES.

Where to buy a Unilos Astra septic tank from the manufacturer with turnkey installation

If you decide to order the installation of a septic tank from certified suppliers and dealers of Unilos Astra, then you can count on special sales conditions, Additional services, discounts and even buy a septic tank on credit. What is a septic tank in the classical sense? A septic tank is a sealed structure for mechanical cleaning sewage wastewater with anaerobic digestion of sludge. But over time, septic tanks have become increasingly improved and today they represent entire autonomous stations for the deepest wastewater treatment and sludge treatment using a whole range of technological processes: physical, biological and chemical.

On the company website "SepticPro-MSK" you will be able to choose the currently most popular biological wastewater treatment plants of the Unilos brand, Astra series. If your country house is not connected to the central sewer, then you need to install a septic tank, which is installed by our company in Moscow and the Moscow region.

How do Unilos Astra septic tanks differ from other autonomous sewers?

There are three main types of septic tanks:

• Storage septic tanks,
• Septic tanks with soil purification,
• Septic tanks for deep biological treatment.

Storage septic tanks - These are septic tanks that essentially provide an improved cesspool. The design of such septic tanks consists of a sealed container, which is at the same time a receiver, storage and settling tank for sewage water discharged through a sewer pipe from the home. As the tank fills, the owners of the house call sewer trucks to pump out the septic tank. The undoubted advantage of such septic tanks is their simplicity and low cost, but the disadvantage is the regular need for cleaning and an unpleasant odor when pumping wastewater. Such septic tanks are not suitable for houses with permanent residence, since the container fills with wastewater quite quickly.

Soil post-treatment septic tanks - this is a type of septic tank where wastewater first flows into a septic tank. In the first chamber or compartment of such septic tanks, wastewater is separated into fractions, and then water purified from heavy, large and solid inclusions through an overflow pipe enters the second compartment, where further purification of contaminants occurs using anaerobic bacteria. If the volume of wastewater is large, then there may be several such tanks, and they are all connected by overflow pipes. But no matter how much contaminated water is poured from one section to another, it is not possible to purify wastewater in such a septic tank by more than 60%. Discharge of wastewater with such quality of treatment is prohibited by SanPiN standards. Therefore, for such septic tanks, post-treatment of wastewater with soil is used. Filters are installed based on drainage pipes and special wells equipped with built-in soil infiltration. The advantage of such septic tanks is the less frequent need to call a sewer truck for pumping and the complete energy independence of the entire structure. The disadvantage of septic tanks with soil post-treatment is the need to use special biological additives and anaerobic bacteria and the fact that they cannot work well in areas with clay and loamy soil and where underground groundwater is located too high. Another problem with such septic tanks is that the soil for the filtration fields needs to be replaced every 3–5 years. And the installation of such septic tanks itself is quite complex, labor-intensive and very expensive.

It is worth paying attention to the fact that all biological sewage treatment plants use one or both technological processes: anaerobic digestion and aerobic decomposition method. When anaerobic bacteria break down organic compounds in the complete absence or lack of oxygen in the air, and aerobic microorganisms require oxygen for their vital functions. As a result oxidative processes with the direct participation of aerobic bacteria, pollution of organic origin breaks down into simpler inorganic components - with the formation carbon dioxide, water and nitrite compounds, which is called mineralization. Aerobic technological process provides a significantly higher level of purification.

Septic tanks for deep biological treatment - such as Unilos Astra series use today the most modern and effective technology wastewater treatment. The treatment system is designed in such a way that sewage wastewater is 98% purified and can be discharged directly into the ground. And when installing additional equipment You can even dump water in the reserve area.

Installation of a septic tank for deep biological treatment Unilos Astra is a solid vertical sealed block, which is divided inside into several chambers. Various chemical and biological processes take place in these chambers to break down, break down and remove waste pollutants from household waste and feces.

The principle of operation of the Unilos Astra septic tank

1) Domestic sewage and fecal wastewater enters the receiving chamber, which contains a film membrane aerator that increases the settling effect. Air bubbles break down large particles of contaminants into smaller ones, while saturating them with oxygen. This is necessary for further more efficient productive activity aerobic bacteria. At the same time, gravitational sedimentation of suspended particles and primary mixing of wastewater with active biological sludge occurs.

2) Special pumps - airlifts, triggered by level sensors, forcibly discharge pre-prepared wastewater into the aeration tank chamber. This chamber contains a device for biological wastewater treatment with air aeration. It contains a grease trap and a collection of light particles and fibers, the so-called hair trap; not only hair and pet hair, but also dust clots settle on it. This chamber houses the main purification system - a bacterial biofilter, which works on the principle of passing wastewater through a load with a biological film of aerobic microorganisms. As a result, the process of oxidation of waste organic matter with its further mineralization is started. In this chamber, the generation of activated sludge occurs, which, in general, is present in all chambers, but in different concentrations.

For reference. Activated sludge is large colonies of bacteria and microorganisms that form and live in a septic tank. Activated sludge plays a key role in the course of biological processes, which makes it possible to achieve 98% wastewater treatment. All important microorganisms that perform the main function of active wastewater treatment accumulate in this substance, which is why it is called activated sludge.

3) From the aeration tank, the liquid flows into a secondary settling tank, where mechanical separation of water and sludge occurs. Fractions of different weights can reach the final stage of purification, rising to the surface, but the Unilos Astra septic tank filter system captures even the smallest particles and sends them back to the chamber for recycling with a bioactivator.

4) The sludge receiver chamber is designed for excess waste sludge with dead bacteria that can no longer take part in biological filtration.

5) On final stage purification water is removed from the treatment plant using a pump or by gravity.

The body of the Unilos Astra septic tank is compact and has low weight and dimensions, as well as mounting loops, so it is easy to transport and install. The Unilos Astra septic tank is resistant to mechanical, chemical and temperature influences and is absolutely sealed, therefore it does not allow unpleasant odors to pass through and prevents the flow of untreated wastewater into the soil. The Unilos Astra septic tank is designed for an operational life of 50 years, but with good maintenance of the septic tank, more is possible. The operation of the Unilos Astra septic tank is fully automated, all processes are controlled using an electronic control unit and water level sensors. In the event of an emergency, for example a blockage of the main pump, the built-in alarm system will turn off the operation of the installation and notify about the malfunction with a light signal, informing about the need to call service. The Unilos Astra septic tank is very easy to maintain and eliminates the need to call sewer trucks. Excess waste activated sludge is pumped out using a built-in drainage pump 3-4 times a year. In this case, the spent activated sludge has the appearance of ordinary lake sludge and can be used for compost. The Unilos Astra septic tank for a country house can be installed even with high level groundwater, since it is always full and does not float. Well Septic tank Unilos Astra is suitable for clay and loamy soil.

The most important advantage of the Unilos Astra bioseptic tank is its ability to purify waste water to the point of secondary use, for example, for watering trees and other vegetation in the garden. Moreover, if you purchase a frame-fill filter separately and install a UV disinfectant with an ultrasonic cavitation unit, then the quality of the discharged process water can be brought to the level of drinking water.

For reference! In conventional septic tanks, the pumped out sludge can be composted and only after 1–2 years used as natural organic fertilizer. And the aerobic stabilizer of excess activated sludge in Unilos Astra allows you to use biomass from waste as fertilizer immediately after removing it from the station.

Unilos Astra bioseptics also have disadvantages. The most big drawback can be considered the energy dependence of the station. Before placing an order for the installation of a septic tank for a country house or cottage, you should consider the possibility of failures in the electricity network and power surges. In terms of energy consumption, the Unilos Astra septic tank is comparable to washing machine. Plus the cost of bioactivators - it is important to maintain the population of aerobic bacteria in the bioseptic tank at the required level, so once every 1–2 years, usually before the onset of winter, they will have to be purchased and added to the aeration tank.

Selection of a septic tank for a country house or cottage according to the number of permanent residents.

Selecting a Unilos Astra septic tank is not difficult: the number in the name indicates the maximum number of users. For example, the Astra 3 septic tank model is suitable for small house with 3 permanent residents, and the Astra 10 septic tank is suitable for a cottage with a large family for 10 people.

The productivity of the Unilos Astra septic tank is calculated as follows: the number of users must be multiplied by the water consumption of one person per day, which on average is 200 liters. Thus, the productivity of the Unilos Astra 3 septic tank is 600 liters per day.

Maintenance of septic tanks Unilos Astra

Company specialists "SepticPro-MSK" carry out regular maintenance of Unilos Astra septic tanks in the Moscow region. Maintenance of Unilos septic tanks is necessary to maintain stable, productive and durable operation treatment facilities. The station owner can carry out part of the complex of service work, since routine care does not require a septic tank special knowledge or skills. However, it is recommended to delegate some of the tasks for caring for Unilos to specialists, since professional supervision of the system’s operation will avoid breakdowns and subsequent expensive repairs.

Maintenance of Unilos Astra cleaning stations includes a list of the following activities:

• Visual monitoring of the status of the Unilos system. It is necessary to evaluate the level of purified water - approximately twice. To do this, open the lid of the septic tank and make sure there is clean water in the container. During installation, the tank cover must remain above the ground. During the operation of the system, sludge accumulates in the septic tank, which is a product of biological treatment.
• Sludge removal. In systems like Unilos, this process is almost completely automated: you only need to prepare a container into which the sludge will be discharged. Since during the cleaning process it goes through an aerobic stabilization cycle, there is no unpleasant odor. Frequency – once a quarter.
• Pumping out sludge with a pump. If you did not carry out the measures described in the previous stage, you need to pump out the formed sludge from the container with a drainage pump. Frequency – once every 6 months.
• Cleaning filters, membranes, aeration tanks. Every six months, be sure to: clean the hair filter in the aeration tank. Once every 24 months, replace the membranes in the compressor unit. Once every 5 years - clean all system containers and replace components.

These tips apply to all modifications of the Unilos system. The frequency of work organization depends on the intensity of system operation. Remember that the permissible level of discharged water must not be exceeded. It is believed that when caring for a septic tank yourself, it is necessary to clean the sewer 1.5 times more often (due to the lack of professional equipment and proper experience).
