Cleaning and recycling of production waste has become a worldwide problem these days. Its solution depends on what treatment facilities are used at each, even the smallest enterprise, for example, a gas station.
Biological treatment facilities are designed for complete biological treatment of all types of wastewater, including household wastewater, as well as industrial and domestic wastewater from industrial enterprises or residential settlements.
The biological method uses the laws of biochemical and biological self-purification of water bodies, based on the ability of microorganisms to use organic substances in wastewater for nutrition, which are a source of carbon for them. Bacteria actually eat the waste, recycling it for their own life.

Autonomy, environmental friendliness and ease of maintenance of the cleaning device served as important selection criteria.
GRINLOS “Prom”
The modular plant provides biological treatment of industrial and domestic wastewater in the absence of a centralized sewage system. The principle of operation is based on an environmentally friendly technology for the treatment of wastewater by aerobic and anaerobic microorganisms in an airy and anoxic environment. Contaminated liquid may flow unevenly, for example when emptying storage tanks.
Structurally, the cleaning system is made in the form of a horizontal cylinder made of sheet polypropylene. The internal volume is divided into sections with rectangular maintenance hatches on top. Depending on the version, the device can serve an industrial enterprise of different capacities, a large cottage, a cottage settlement. In total, the company’s catalog contains 20 options for a treatment station, the most “advanced” model can process up to 40 cubic meters of sewage per day.
The choice of a cleaning station depends on the number of people working in production, on the different amounts of time and volumes of use of domestic services. For example, if the production consists of 30 people, and they use the services as needed, then the Prom 30 station is suitable for them. The most popular models in the line for industrial use are Prom 100 and Prom 150. As a rule, these stations are purchased for cafes, restaurants, hotels.
The operation of the station is based on a multi-stage wastewater treatment technology, which includes mechanical and biological processing. The main participant in the cleaning process is activated sludge. The quality of cleaning will deteriorate if conditions unfavorable for microorganisms arise. That is why you need to follow the rules for using the drainage system. At the same time, it is recommended to observe the general rules for the use of biological treatment systems and aeration installations.
That is why it is categorically not recommended to dump the following waste into the treatment plant:
- Construction waste of all kinds
- Petroleum products and fuels and lubricants
- Chlorine-containing substances
- Medicines and antiseptics
- Lots of animal fur
When installing a treatment plant, you need to find out the need for additional equipment (additional filter, sewage pumping stations, UV sterilizer, desalinator, etc.)

2. Station for the treatment of domestic wastewater LLC “Summa Technologies Water Treatment”
The equipment is designed for cleaning wastewater from industrial agricultural, municipal enterprises, food production, solid waste landfills. At the first stage, large solid particles are screened out with a drum sieve or a grate, then the effluent enters the sand trap and is mixed to average the chemical composition.
Then comes the anaerobic treatment stage, the effluents are mixed with activated sludge without air access to remove nitrates. After that, the effluents enter the aerotank (rectangular tank), where they are enriched with atmospheric oxygen using a fine-bubble aeration system.
In the secondary clarifier, activated sludge settles to the bottom, coagulates and is removed. In the post-treatment unit, special bacteria mineralize the impurities remaining in the water. The final disinfection is carried out with ultraviolet lamps or the addition of sodium hypochlorite.
The equipment is delivered in the form of prefabricated container modules, from which the required configuration of the treatment plant is assembled on site according to the project developed in advance.

How to choose a treatment plant for an enterprise
To determine which station or water treatment complex is required for a particular enterprise, you need to answer the list of questions:
- The nature of effluents (household, industrial, atmospheric).
- The number of people in the enterprise;
- Technical processes and plumbing used at the enterprise;
- Frequency of use (around the clock or only during business hours).
Healthy Food Near Me asked to answer questions Alexandra Misharina, head of the production department of the company “Innovative environmental equipment” and Anton Smolov, commercial director of the PromEcology company.
The complexity of industrial wastewater treatment lies in the fact that they are always non-standard, voluminous and come unevenly, says Anton Smolov. Almost every industrial wastewater treatment system needs preliminary design, and the initial data are the daily and hourly flow volume, a list of chemicals used in production, including cleaning agents.
It is necessary to determine in advance the location of the treatment plant installation and consider the route of the pipeline for wastewater. Analysis, design, selection of equipment, its installation and start-up must be carried out by masters of specialized companies. Savings can lead to ruinous spending on fines due to excess discharge rates and harm to the environment.
Popular questions and answers
Answers questions Alexander Misharin, head of the production department of the company “Innovative environmental equipment”.
What types of wastewater are to be treated?
• Household, formed when using the sink, shower, toilet;
• Surface rainfall formed on roofs and street coverings during atmospheric precipitation:
• Production, formed during technological processes and equipment washing.
What are the ways to get rid of waste
• Collection and removal to the landfill. The simplest, but also the most expensive way is to collect it in sealed containers and take it to a special landfill for destruction. Recycling is carried out by a specialized company and such work costs at least 100 rubles per cubic meter. The volume of effluents from conventional food production, for example, is from 100 to 500 cubic meters per day. Costs thus grow to astronomical amounts.
• Discharge into the sewer. The process is regulated by Decree of the Government of the Federation No. 6441 and local regulations. Large fines are imposed for exceeding the norms. Household effluents can be discharged into the sewer without treatment, but almost all industrial effluents need to be treated before being discharged into the sewer.
• Discharge into a pond or ditch. This requires approval by the committee on nature management and other organizations responsible for the environment. To be discharged into a reservoir of the highest category, the water must be purified almost to drinking water.
• Reset to terrain In most cases forbidden. There may be exceptions, but they require complex approvals and large undeveloped plots.
• Return of treated effluents to production possible, but expensive and therefore not yet economically viable, says Anton Smolov.
Are wastewater treatment plants mandatory for all businesses?
