Cleaning the supply air from odors. Air purification from odor in cooking

Welcome to the pages of my blog, friends!

Everyone knows that a polluted atmosphere causes illness, headaches, coughs, and shortness of breath. Moreover, the indoor microclimate is much dirtier than outdoors. How is air purified from odors?

There are always particles of dust, human skin and animal hair, fungal and mold spores, poisonous gases, toxins and other poisonous compounds in the air.

Modern industry produces powerful cleaning systems that will clean the microclimate not only in homes and offices, but also in restaurants, production workshops and other places where there are large crowds of people.

Choose best option A sales consultant will always help. Let's figure out how to improve the microclimate where we spend the most time - in our homes.

Let's talk today about what means available to each of us that will help get rid of unpleasant and harmful miasms.

Why are foreign odors not allowed?

There are thousands of particles and compounds floating in the atmosphere, including carcinogenic and others that can cause illness. They are the ones who give this or that smell.

Let's find out some of the substances that we have to breathe in our lives:

• exhaust gases from cars and industrial enterprises;
• farmaldehyde, styrene and other compounds that highlight furniture and other items of surrounding interior and decoration;
• tobacco smoke and burning leaves, garbage and other fires;
• aromas from cooking;
• household chemicals and cleaning products;
• allergens from pets.

Unpleasant odors are a symbiosis of solid and gaseous compounds, allergens, viruses and harmful gases.

They are not only harmful to health, but also irritating, causing headaches, sore throat, sore eyes and tearing.

But not all gases are used by our brain olfactory receptors can recognize, but fighting them, although not easy, is necessary.

Secrets of a clean microclimate

Getting rid of them is not as easy as it might seem. Cleaners are not a solution, since they themselves contain a stronger aroma, which temporarily “interrupts” the unpleasant one.

Firstly, this is a short-term effect, and secondly, the cause has not been eliminated, so the stench will be felt again.

In addition, indoor convection and diffusion cause molecules in the atmosphere to quickly spread indoors.

Most effective method To overcome amber in an apartment is to ventilate it.

But in large, industrial cities, during the period of burning peat bogs or forest fires, in the fall, when there is always acrid smoke from burning leaves on the street, this method is not only unacceptable, but will pollute the atmosphere in the apartment even more.

Modern industry makes it possible to cope with this problem: now there is a huge selection of cleaners that will get rid of all kinds of odorous components.

They are able to cleanse space of all kinds of gases, gradually reducing their concentration.

• Air purifiers

These are filters for various rooms. They should be used in apartments, offices, educational institutions, medical institutions, public places and production.

Modern air purifiers are multifunctional:They help filter out harmful allergens, dust, kitchen odors, harmful compounds, all solid and gaseous compounds that are present in the atmosphere.

In addition to cleansing from contaminants, they disinfect the microclimate and make it healthy. This result is obtained thanks to a multi-stage filter system: they remove all dirt and stench from the space.

The first step is to filter out coarse particles: villi, pollen, textile particles and dead human skin, dust, etc. after this, microparticles are eliminated.

Afterwards, aromas and gases are filtered out. The airflow then passes through the UV rays. Ultraviolet treatment works great against viruses and pathogens.

This is the most expensive and reliable device based on carbon filters. Whoever has the opportunity, purchase this option, since it is not profitable to save on health.

But for those whose financial resources do not allow it, more budget options can be used.

• Ionizers

Ionizers - under the influence of electric current, electrons are released into the environment, which interact with oxygen. As a result, ionization of the atmosphere occurs.

The result of the device is that dust and unpleasant odors are absorbed, and the space becomes favorable and clean.

Today, most people clean the air from odors in their apartments thanks to a large number of different neutralizers in the form of a block, spray or gel.

The principle of operation of such products is based on the fact that molecules of harmful and unpleasant odors are neutralized due to the evaporation of such a product.

So, the spray is sprayed directly into the rooms, the block releases neutralizing substances into the space and the gel can be left in a convenient container.

The owner can regulate the effectiveness himself: by increasing or decreasing their dosage, but do not forget that this is not eliminating the cause, but only a kind of disguise.

There are several more ways to change the microclimate in an apartment using fragrances. These are all kinds of aromatic oils, sticks, candles.

They don't get rid of odors, they just change them. Be careful when using these products as they may cause allergies or headaches.

Especially if you exceed their dosage. If you light an aroma lamp and feel a headache, nausea, or a sore throat, immediately turn it off and check the room.

This rule is also relevant for synthetic air fresheners: use carefully, in small quantities, carefully monitoring the reaction to the drugs.

Preventive measures

Our well-being often depends on what we breathe throughout the day. Therefore, daily walks in places where a large number of green spaces.

In the morning or evening, take a walk or go for a run. These activities will saturate your blood with oxygen.

While on the street, do a set of simple breathing exercises. As a result, you will feel a surge of vital energy.

Diet can also give you a boost of energy. A healthy diet does not cause drowsiness, but on the contrary, it will give you a boost of energy and strength. Change your diet and you will feel a surge of strength.

This step makes it possible to get rid of many ailments without medications, sometimes even the most severe ones, such as asthma, oncology, dermatological problems and various diseases of the gastrointestinal tract and other internal organs.

Vegetarianism And raw food diet- This is a way of healing and rejuvenation. Live food allows you to regenerate cells, gives a colossal boost of energy, heals.

Try this diet, but do not rush to change your diet without preparation - this can provoke an exacerbation of chronic diseases and result in failure.

Take advantage of the help of specialists who will provide the necessary knowledge absolutely free of charge, reveal all the secrets and share useful tips and recipes. This menu is very tasty and varied.

The raw food diet has analogues to the foods we love. The raw food diet includes soups, borscht, pizza, Chinese, Japanese, Italian traditional dishes, and sweets.

Anyone can prepare them, or purchase them at super store for raw foodists and vegans.

Here you will find your favorite sweets: chocolate, candies and bars, marshmallows, jams and cookies. And powerful, reliable equipment, which you order here, will help you prepare other raw food and vegan dishes at home.

Avoid coffee and alcoholic drinks. With the help of water, you will not only quench your thirst, but also remove waste and toxins from the body. Drink more clean water - it is beneficial for your health and appearance.

Hydration occurs from the inside: the skin receives the necessary moisture, becomes elastic, and the network of fine wrinkles is smoothed out.

These simple changes can significantly improve everyone’s health and well-being.

I wish you all all the best and good health!

In any apartment where there is a smoker, there is always a recreation area in which the concentration of cigarette smoke is increased. To change the situation in better side use an air purifier to remove tobacco smoke.

The composition of cigarette smoke includes up to 4 thousand components, the vast majority of which cause irreparable harm not only to smokers themselves, but also to people who are forced to stay in a room saturated with tobacco smoke.

Constantly staying in an apartment where people smoke often can cause lung cancer, heart attack, bronchitis, not to mention an allergy to smoke. If you do not disinfect the air in your apartment in a timely manner, then a visit to the hospital is not far off.

When you don't have enough willpower to quit smoking, you need to use an air purifier. It will help reduce several times Negative consequences from smoking. Such devices effectively neutralize harmful volatile components and fatal toxins that are found in tobacco smoke.

Productive operation of the air purifier protects furniture and room decoration from the smell of tobacco. Unfortunately, there is no such device that could completely eliminate all types of impurities in the atmosphere, but a good air purifier must reduce them to a minimum level.

The basic principle of operation of anti-tobacco devices is the repeated passage of room air through special filter systems.

Such a household appliance consists of two main parts:

• a fan that sucks air from the room;
• a block of filters, each of which has its own function and degree of purification.

The fan passes air from the room through itself and directs it to a set of filters. Leaving it on the filters harmful substances, clean air flows back into the room.

More modern devices contain ionizers that disinfect the exhaust air.

Filtration itself can be divided into three stages:

1. Pre-cleaning phase. At this stage, the air flow leaves the largest particles of harmful substances on the inlet pre-filter.
2. Absorption stage. For the best absorption of tobacco smoke fractions, two filters using potassium and activated carbon. Using a carbon filter kills not only tobacco smoke, but also other unpleasant odors.
3. Final cleaning. The air is intensively forced through a fine filter that adsorbs the smallest particles of dust and other harmful substances.

The filter unit must contain several units - this is the key to clean air for the home.

Efficiency of cleaning cigarette smoke

The basis for the fight against smoke is the principle of reusable passage of air with a cigarette smell through a complex system of filters. Even if there is a lot of frequent smoking in the room, repeated filtration can help effectively clean the air from tobacco smoke.

Important! The main advantage of devices of this type is getting rid of tobacco and its carcinogenic components, and not saturating the air with various flavors.

Based on filter systems, purifiers are divided into several types.

1. The electrostatic type cleaner is primarily characterized by the lowest price while maintaining acceptable quality. The air inside such devices passes through positively charged electrodes, and the smallest smoke particles collect on the surface of the filter with a negative charge. The ionic purification principle allows you to capture particles with sizes less than 1 micron. It is advisable to purchase a model with a built-in ozonizer. Thanks to ozone, the room air will be cleansed of all kinds of bacteria and toxins.

   The electrostatic type device consumes a minimum of electricity with a low noise level. Easy to use: requires wet cleaning plates once a week. Such washing is permissible up to 250 times, which significantly increases the service life of the device.

2. A number of air purification devices are equipped with removable filters; a similar type of design has found its way into vacuum cleaners. Mechanical filters, on the one hand, collect a larger number of microparticles of tobacco smoke in one air pass, on the other hand, they become dirty quite quickly and are not subject to further use. Structurally, they are disposable elements and require periodic replacement every 5-6 months. Replacing the filter is extremely easy, but its cost is quite high.
3. To the class of the most modern household appliances Photocatalytic type cleaners can be considered, although their high cost must be taken into account. They use the combined effects of ultraviolet light and a catalyst as cleaning tools. Devices in this class convert tobacco smoke and toxins into neutral carbon dioxide and water. The splitting itself occurs at the molecular level, as a result there are no layers of dirt on the device.

   Such a device does not require preventive cleaning, the filters can last a very long time, only the UV lamp requires replacement once every three years.

   But such cleaners also have disadvantages. They consume quite a lot of electricity and are quite noisy.

4. The latest achievements include ultrasonic installations. They can regulate humidity both manually and automatically, since, in addition to effective cleaning, they still maintain the necessary level of air humidification. For this purpose, the design includes a hydrostat.
   Purification occurs by driving the incoming air through a water film of small splashes. Harmful substances practically “stick” to the water surface and subsequently dissolve in water. This type of air washing requires constant replenishment of water in a special container of the device. The price of such a device is quite high, and the level of purification is inferior to photocatalytic devices.

Features of cleaners

The level of purification and the quality of the surrounding atmosphere are directly related: the higher the first indicator, the higher the second will be. In various devices, the air flow capacity ranges from 400 to 2600 m 3 /hour.

Electricity consumption can also fluctuate between 50-200 W. A properly selected purifier will consume 10-15 W, this power is enough to keep the air within normal limits over an area of ​​25 m2.

The absence of moving mechanical parts allows the device to operate almost silently. Power can be supplied either from the AC adapter or from a battery.

Various cleaning modes can be controlled:

• mechanical switches;
• from the remote control;
• automatically, the device automatically turns on/off at a certain saturation of air with smoke.

Installation of purifiers is possible almost anywhere: in a suspended ceiling structure, on a wall, on the floor.

Choosing a tobacco smoke cleaner

Having understood the principle of operation and decided what this device is needed for, you can choose the right model. The following factors must be taken into account:

1. The area of ​​the room must correspond to the performance of the device. It is especially necessary to coordinate the parameters precisely if the model has an ionizer.
2. The purification system must correspond to air pollution factors.
3. Noise level, which is important, especially in night mode. The ionic cleaner operates almost silently, unlike analogues with mechanical cleaning.
4. Dust level in the room. The air may contain a large number of different components (six animals, carpet particles and much more), in which case mechanical cleaning is preferable.
5. The choice is narrowed if there are allergy sufferers in the apartment. Photocatalytic devices remove allergens well.
6. An important quality is the compactness of the device and the ability to move it indoors.
7. Convenient control buttons and mode switches.
8. The degree of air disinfection, which is extremely important during the period of exacerbation of viral diseases. In this case, devices with ozonizers are most effective. Ozone is many times more productive than ultraviolet radiation.
9. Good air - wet air. The presence of a humidification function significantly increases the useful properties of the device.
10. The air that passes through the filter system loses most of its natural charge, so choosing an ionizer is desirable.

When purchasing a purifier, you must also take into account the financial factor. Whether it is a budget option or a complex combination device, the air in the room will become much better. Therefore, in the expected set household appliances There must be a place for an air purifier.

As an example, the main characteristics of the most popular devices are given.

Where can I buy

A biofilter is a biologically active fixed bed reactor for purifying air or water. Its main purpose is to filter gaseous impurities and substances dissolved in the substance being purified, rather than solid particles.

The idea of ​​purifying exhaust air biologically arose in the seventies of the twentieth century, but was first put into practice only in 1980 thanks to intensive research by scientists. Based on microbiological techniques, a few years later the concept was developed modular installation with the possibility of universal use.

The oxygenate is closed and poorly ventilated. When ozone is converted to oxygen, it allows you to breathe cleaner air. Rooms Sleeping facilities in a virus-free, hygienic and odor-free environment help residents feel more comfortable and safe. Ozone not only keeps the user safe from infections, but also makes the user feel very satisfied. In addition to respiratory allergies, dermatitis causing eczema should also be considered. Although dust mites, pollen, fungi, etc. cannot be completely eliminated in any environment, ozone can be brought to acceptable levels for allergy sufferers.

Biofiltration is a relatively simple and cost-effective process for cleaning exhaust air containing volatile organic compounds and odors. At the same time, microorganisms decompose harmful and odorous substances into harmless products such as carbon dioxide and water. Biofilters are used primarily for air purification. For specific cases, biological wastewater treatment is also possible, based on a similar principle.

Additionally, when a resident suffers from infectious disease or incontinence, “mattresses and pillows are burned; but ozonation allows reuse under optimal hygienic conditions, avoiding the replacement of these items, which are always much more expensive,” explains Inez.

Therefore, they are centers of disease transmission. When using ozone, make sure you are breathing clean air, free of odors and germs. Prices Overall, ozonated water cleaning eliminates the use of chemicals in cleaning and maintenance procedures and also provides a high level of sanitation. These ozonated water treatment systems can save time, reduce costs and protect the environment.

Biological exhaust air treatment uses microorganisms to remove harmful substances from the air through microbiological degradation. Various microorganisms, such as bacteria or fungi, act as decomposers.

The whole process boils down to the following: microorganisms convert harmful substances with the help of oxygen into carbon dioxide and water, which means that we are talking about a decomposition reaction of matter.

For example, use in laundries is an effective alternative that reduces hot water consumption, reduces wash time, saves detergent, increases whiteness, and increases clothing life. This system can be installed in small washing machines as well as in large washing tunnels. Simply put, ozone gas must be transferred to the water.

According to the World Health Organization, food hygiene includes all necessary measures to ensure the sanitary safety of food, maintaining all other qualities that are its own, with special attention to nutritional content.

This reaction can only occur when harmful substances pass from a gaseous state to a liquid state, since water constitutes the living space of microorganisms. That is why the transition of harmful substances into a liquid state is the most important factor in all biological methods. Only those microorganisms survive that can best adapt to the prevailing conditions and nutritional base. In this case, we are always talking about a mixture of various heterotrophic species that use harmful substances in the air as a source of carbon and energy.

Microorganisms are present in the environment and in all living things. Pollution food products originates from any of these sources, and processing and distribution operations provide new opportunities for contamination. To prevent food contamination, it is important that kitchens maintain not only proper cleaning conditions, but also hygienic conditions. In cold rooms where fruits and vegetables are stored, ozone quickly eliminates possible microbial contamination, which means longer storage times in the rooms.

Types and methods of operating biofilters

There are different types of biofilters depending on their method of operation and application. For example:

• flat sleeve,
• container type,
• for wells,
• storey,
• cell phone,
• tower.

But in all types of devices, the exhaust air passes through some kind of filter material.

Regarding industrial fume hoods Although they have some filtration and retention of condensed vapors, oils and greases, the resulting air is very imperfect in all aspects. In addition, microcontamination that forms inside the exhaust channels can be very high. Each ozone can also successfully combat it, Ynes manifests.

In addition, as the Ozone 21 manager explained, other types of odors come from kitchens that contribute to indoor air pollution in centers: cooking, frying, etc. Ozone perfectly controls these emissions, and if the device is placed in the entrance outlets of kitchens, an ozone curtain is created, which prevents odors from entering the residence, and also leaves food directly in the premises. Ozone, in addition to eliminating odors produced by the food industry, guarantees its complete safety and helps maintain better taste and texture for consumption,” says Rodriguez-Rosello.

In some cases, an air-washing chamber is located in front of the biofilter, in which the gas acquires a relative humidity of almost 100%. This should prevent the material from drying out. In addition, if necessary, solid particles are removed from the gas in the air washing chamber. The raw gas, saturated with water vapor and cleared of dust, enters directly into the biofilter, which contains the filter material. Thanks to additional irrigation, it always remains moist. This is where microorganisms live. When passing through the filter layer, substances in the exhaust air are sorbed on the surface of the material, thus becoming a nutritional base for the bacteria living here.

Ozone against chlorine and bleach. Although chlorine is the most widely used method, "chlorine is a toxic halogen gas that causes serious health damage if exposed to significant quantities in its pure state." Meanwhile, ozone is a gas that ends up dissociating and returning to be oxygen without causing any harm, Rodriguez-Rosello insists. And, most importantly, chlorine has an unpleasant odor in the face of ozone, “which is colorless and tasteless.”

Finally, this expert points out that chlorine needs a warehouse to store the product, but ozone does not, since it is a generator. As for bleach, Ozone 21 is a toxic agent that is highly corrosive and can cause burns or irritation to the skin, eyes and respiratory system. If swallowed, it can cause serious health problems and should never be mixed with ammonia as the fumes they produce are very harmful. Ozone has none of these problems and their disinfecting power is much greater than that of lye.

To guarantee high microbial activity in the filter, the following must be observed: optimal conditions for the life of microorganisms: pH level, humidity, temperature and regular supply of nutrients. Practice shows that mixed microbial populations developing in biofilters are very resilient if the above conditions are met.

In addition, ozone is more effective, safer and non-aggressive to fabric fibers. Installation of ozone generators. The size of ozone generators and their installation depend on the intended use. For specific room dosing or shock treatment, we may use a portable unit or separate ozone generators. the benefits it creates "are not an expensive product and represent more of an investment than the cost of servicing."

In the same vein, José Juan Rodríguez-Rosello points out that Ozone 21 recommends the most suitable ozone generator and its installation for each application point. For example, in bathrooms, rooms and common rooms can be installed in a suspended ceiling, as it only requires electric outlet. But there are also mobile phones that do not require installation. Meanwhile, water models are easy to place on the faucet and, depending on their use, may or may not require electricity.

Filter material

There are also certain requirements for the filter material.

It must have a large specific surface and at the same time a comfortable breeding area for microorganisms, which:

• retains moisture well,
• allows only a slight drop in pressure during the passage of gas,
• independently regulates pH fluctuations,
• ensures uniform passage through the filter layer,
• has a low decay rate.

In addition, microorganisms must be supplied with inorganic nutrients and trace elements. The following materials can be used as a filter layer:

From a cost perspective, Rodriguez-Rosello notes that the use of ozone improves the quality of life for residents, their families and workers. In addition, all people will have better health, which Ozone 21 not only sells the devices, but also rents them at a lower price and includes the use of ozone generators. installation, report on ozone measurements in the places where it is installed, supervision and replacement of devices with others in perfect condition once a year.

Did you know that ozone is used for cleaning and that it is a better disinfectant than chlorine and bleach? If you are looking for an alternative cleaning technique and are truly respectful of environment, then ozone cleaning is what you need. Ozone has hygienic and deodorizing properties. Ozonation may be your best choice after painting your home or getting a job done. Continue reading and learn all the properties, uses and benefits of ozone cleaning.

• Compost from wood or waste
• Heather, brushwood or coconut fibers
• Peat products
• Paper granulate

Additionally, inert materials such as expanded clay, styrofoam or polystyrene are added for loosening. In this case, the filter layer is not only a carrier for microorganisms, but also a supplier of nutrients.

What is ozone and what is it for?

Ozone is a molecule made up of three oxygen atoms. In its natural state, ozone is a somewhat bluish gas with a pleasant odor. Although ozone molecules are present in the air, they do not serve as a disinfectant. To achieve this function, we will need ozone generators, also known as ozonizers.

When these molecules come into contact with particles that cause infections or stench, they are removed and converted into oxygen. Ozone applied to environments or surfaces that are stained or that produce an unpleasant odor has numerous benefits.

Advantages and disadvantages of biofiltration

When operating a biofilter, the main problem is to prevent drying out or excessive wetting of the filter layer, and, consequently, ensuring uniform passage of contaminated air through it.

This can be achieved, first of all, by encapsulating biofilters. The disadvantages of these devices include the following:

Ozone disinfection is very effective as it eliminates bacteria, germs, fungi and other microorganisms. These molecules are also able to stop unpleasant odors caused even by fish. . Ozone disinfects and leaves well. However, it does not affect the material on which it is applied. That is, it leaves the surface new and does not change its fire retardant or acoustic insulating properties.

Disinfecting effects of ozone

Professional Ozone Cleaning Services

• Ozone acts against each of them and destroys them.
• In addition, it slows down their growth and prevents them from appearing again.
• Virucidal effect.

The uses of ozone are countless in terms of purification.

• large footprint
• energy costs for increasing pressure
• need for additional irrigation

However, compared to other methods, such as air ionization using ionizing tubes, the permanent biological cleaning process is more advantageous due to CO2 savings and numerous economic aspects (average purchase costs, long service life, average production costs).

Office cleaning with ozone

More and more more companies and individuals discover the benefits of this gas and decide to hire an ozone purifier for their facilities. Offices are workplaces that are usually closed, so the air you breathe is concentrated. In addition, there are many people who usually go to their post even if they have a little cold. The main problem is that workers use the same printer and touch door handles, but they don't always have clean hands. In addition, they cough, sneeze and breathe the same air.

Technological basics

The technological basis is essentially biochemical oxidation and, at the same time, the decomposition and transformation of materials by bacteria, fungi and yeast into substances that are harmless and do not have unpleasant odors.

The prerequisites are that the hazardous materials are water-soluble, biodegradable and non-toxic to microorganisms.

Therefore, there is a high risk of infection between them. The best prevention Concerning the health of all company members is to negotiate good office cleaning services. Daily tasks are very important, but we cannot forget about integral cleaning. From time to time, any office needs the carpets cleaned, the upholstery cleaned, or the roof cleaned.

Maintaining impeccable ventilation ducts is also important for breathing good air quality. An ozone air purifier can be very beneficial for a fresh and fresh environment. The processes that take place there collect large amounts of dirt and bacteria. Every industry has different cleaning needs, and while all of this needs to be done strictly, Special attention should be given to the food sector.

The rapidly growing population of microorganisms living on the filter layer uses volatile organic compounds contained in polluted air for their own metabolic processes. Decomposition occurs under aerobic conditions and sufficient oxygen. The latter is ensured by its sufficient content directly in the air. It is necessary to use exhaust air saturated with water vapor, since the filter material must be moist.

Application areas of biofilters

• Biofilters are used for biological air purification in the following areas:
• Cleaning stations Wastewater
• Solid waste landfills, waste treatment plants
• Enterprises for painting surfaces using solvents (metal, wood, plastics)
• Food processing, mushroom farms, smokehouses
• Oil mills and malting companies
• Agricultural installations
• Biogas plants, processing of gas from organic waste
• Cattle farms
• Feed production plants
• Slaughterhouses
• Sludge drying plants
• Industrial production complexes

Biofiltration to eliminate unpleasant odors

The main area of ​​application of biological filtration devices is air purification from unpleasant odors. The microbiological breakdown of odor-producing substances into carbon dioxide and water occurs at ambient temperature, so there is no need to use additional energy or additives. Therefore, the production costs of this process are very negligible. In many areas, biofiltration is becoming an integral part of the technical equipment of production.

In Europe, thousands of biofiltration devices are used to eliminate unpleasant odors coming from a wide variety of emission sources. Unbearable odor problems are often found near wastewater treatment plants, landfills, foundries, breweries, and industrial Food Industry, animal housing facilities, waste treatment plants, agricultural enterprises and slaughterhouses. Biofiltration is the least expensive and most reliable method for eliminating unpleasant odors - its efficiency reaches 99%.

Biofilters for sewer wells

Biofilters for wells are installed directly under the splash guard in the well shaft, thereby preventing strong odors from escaping from the sewer. They contain an integrated splash guard and a filter layer (a mixture of peat and a composite for microorganisms). Water coming from the surface is directed into a suction socket under the slurry collector and discharged through a waste pipe. The rubber gasket prevents the escape of untreated air. Modern filters no longer prevent air leakage. Modern paper-based filters do not require additional maintenance and operate for 5 to 6 years without constant monitoring and maintenance. Their effectiveness is about 99%.

Application

Created for effective elimination unpleasant odors from municipal or industrial sewerage.

Action

Microorganisms in the biofilter neutralize unpleasant odors before they escape.

Design

HDPE (High Density Poly-Ethylene) and stainless steel construction ensures device durability (~7 years)

Container type biofilters

The main purpose of biofiltration is to bring microorganisms into contact with contaminants contained in the air stream. The filtration material that makes up the soil for growing microorganisms is placed inside the biofilter. During the biofiltration process, a stream of polluted air penetrates the biofilter, where the absorption process occurs through the filtration material. The decomposition effect produces metabolic intermediates in the form of CO2 and H2O.

Advantages:

• There is no waste requiring special treatment.
• Pollution is decomposed into neutral compounds such as: H2O, CO2 and biomass.
• The biomass is stored inside the apparatus and after a certain period of time is composted along with the filter material.
• Properly designed biofilters require virtually no maintenance.
• Exceptionally low investment costs as well as low operating costs compared to traditional air purification methods.

Exhaust air requirements

The most important prerequisites for the functioning of biofilters are:

• Maintaining favorable temperature conditions (+5°C - +55°C).
• Irrigation of the filter layer to prevent it from drying out.
• Preventing the formation of cracks and cracks in the filter layer.

Air purification from dust at meat industry enterprises is carried out in accordance with technological and environmental requirements.

To clean supply and recirculation air in air conditioners, self-cleaning oil filters are used. Air purification in supply ventilation systems is carried out in cell oil filters.

Cleaning the supply air from dust is provided for workshops (departments) for raw materials, stuffing, machinery, semi-finished products and packaged meat, as well as varnishing shops for tin and can production.

Dust in the meat industry is released during the preparation of feed, crushing and sifting feed flour, during the preparation of dumplings (sifting flour and other operations), as well as in poultry reception workshops (departments). The released dust is mainly of organic origin, some of its types (flour, feed) are capable of forming explosive mixtures with air.

Cleaning the air removed by local suction from meat and bone, feed, grain and other dust before release into the atmosphere

should be carried out in efficient cyclones, and if necessary, in bag filters, up to the permissible residual dust concentration.

When using air for recirculation, two-stage cleaning is required. In departments for the production of bone meal from dried bone, two-stage air purification from bone dust should be carried out: Stage I - battery cyclones, Stage II - cyclones with a water film or cyclone-washers (see Chapter 6).

Release of air removed by systems into the atmosphere general ventilation from the premises of workshops (departments) of technical and feed products, skinning and raw materials, varnishing and lithographic shops of tin and can production, machine and hardware departments of ammonia refrigeration units, as well as that removed by local suction from equipment (boilers, roasting and gas furnaces, drying chambers, sterilizers, baths for various purposes, vacuum devices, paraffiners, etc.), may be provided without cleaning.

Elimination of unpleasant odors, purification of air from microorganisms discussed in Chap. 6. For meat industry enterprises, these issues are of particular importance, since products that are processed and stored at industry enterprises are a very favorable environment for the development of microflora and the occurrence of unpleasant odors. The number of microorganisms in the air of such premises can reach 10 5 or more units per 1 m 3

People living near meat processing plants often complain about the unpleasant odor emanating from these plants. This happens especially often in the summer and in certain wind directions. *

The destruction of microorganisms is achieved by ozonation, irradiation with bactericidal lamps, the creation of an increased content of carbon dioxide in closed rooms (chambers), and air ionization. A method of eliminating unpleasant odors is to filter the air through a layer of activated carbon. Typically, special cartridges with a perforated surface filled with coal are used for these purposes.

To remove gases that carry unpleasant odors, as well as microorganisms, regular ventilation of premises with outside air is used during the cold season. A good effect is achieved by general ventilation and air removal using local suction.

The method of combating microorganisms is to treat the surface of building structures with bleach, which should be done in the absence of people and products.

As a result of the decomposition of ozone - a triatomic oxygen molecule - monoatomic oxygen is released, which has high chemical activity. It reacts intensively with odor carriers, as a result of which the odor disappears, and oxidizes microorganisms, suppressing their vital functions. As a result of treatment with ozone with an air concentration of 40 mg/m 3 for 3-12 hours a day, 60-100% of microorganisms die in 5 days. Recommended ozone concentrations: in storage rooms for meat products - 1-2 mg/m3, in storage rooms for eggs - 1.5-3 mg/m3, for odor removal in rooms - 5-10 mg/m3.

Almost complete air purification from microorganisms is ensured by fine filters with FP fabric (see Chapter 6). It is also possible to use other filters in which, for example, methylene grün is used for bactericidal effects.

To suppress the development of microorganisms, carbon dioxide is supplied to the air in the meat storage chambers. Its recommended concentration is 10% at a temperature of 0 °C.

To destroy or suppress microorganisms, ultraviolet irradiation is used with the help of special bactericidal lamps filled with mercury vapor. Lamps are installed in air ducts and directly in rooms.

In the storage chamber of chilled meat half-carcasses at an air temperature of 0-10 ° C, relative humidity 85-90%, air mobility up to 0.3-0.5 m/s, bactericidal lamps with a power of 0.15 W are placed at a distance of 600- 800 mm. As a result of turning on the lamps for 30 minutes, 95.3% of microorganisms in the upper part of the room and 78.5% in the lower part are destroyed.

As a result of ultraviolet irradiation, air conditions improve, which leads to an increase in the shelf life of products. When bactericidal lamps are turned on in the sausage storage room for 6 hours a day at an air temperature of 16 C and a relative humidity of 85%, the quality of cooked sausages is maintained for up to 6 days, and for semi-smoked sausages for up to 25 days.

Air ionization leads to the deposition of microorganisms from the air onto building structures. In combination with treating these structures with bactericidal solutions (for example, bleach), this method gives good results.

The problem of getting rid of unpleasant strong odors in a room can sometimes be very pressing. It is clear that the first priority should be to eliminate the source of the odor, but this cannot always be realized. Bedridden patients, repairs on the stairs or at a neighbor's, nearby chemical plants are far from full list such problems.

Odors are not allergens, but they can be allergy triggers. In other words, there is no such thing as an allergy to odors, but an allergic person's increased sensitivity to odors can cause an allergic reaction to a specific allergen, such as pollen or a food product.

What is the nature of smells? These are organic or inorganic molecules that act on our nasal receptors. Most often in rooms we encounter odors of organic origin, the causative agents of which are long volatile molecules. No matter how long they are, their size is always smaller than that of organic particles that cause allergies. Therefore, only those air purifier filters that either break down these molecules (photocatalytic or thermodynamic) or absorb them (carbon) can “fight” them.

Thermodynamic Although purifiers break down molecules of organic odors, due to their low productivity, they make this process ineffective.

Carbon filters have a limited resource for saturation with such molecules, so they must be changed periodically. The less carbon filter(by volume and surface area), the more often it requires replacement (every 1-3 months). Large, heavy carbon filters are changed less frequently (up to once a year), but their cost is significantly higher.

Unrivaled in odor control photocatalytic filters(there may be variations in the name - ion, plasma cluster, etc.). Many air purifiers with these filters have good performance and built-in electronics to ensure automatic adjustment fan speed depending on the presence of foreign odors.
