Rating of the best biological treatment plants for 2022

One of the most important engineering systems in the house to ensure a comfortable stay is sewage. Only if it is available, it is possible to install and operate a kitchen sink, modern household appliances, a washing machine or a bathroom. However, not every country house or cottage has the ability to connect to a centralized sewer network. At the same time, the solution options in the form of a cesspool or a metal barrel are completely irrelevant due to the reasons for causing irreparable harm to the environment, a short service life and unaesthetic performance.

Forgetting about outdated methods of getting out of an unpleasant situation allows the use of a biological treatment plant (SBO), which, thanks to bacteria, allows you to process sewage to a safe level. The resulting water can be watered plants or used for other technical needs.

This review will help you navigate among the models of the best manufacturers on the domestic market in order not to make a mistake when choosing the best device for your home or site.

General information

A biological treatment station is an autonomous complex device for receiving wastewater, processing it with the help of active microorganisms and discharging purified water through a distribution well with a drainage pump into the ground, ditch or special tank.

Effluent contaminants can be organic or inorganic. They include:

• compounds of acetone, benzene, glucose, ethanol, etc.;
• proteins, carbohydrates, fats;
• nitrogen and chloride compounds;
• potassium;
• calcium;
• phosphorus;
• surface-active substances (surfactants), sulfates, phosphates, etc.

When decaying, organic compounds fall out in the form of putrefactive sediments, emitting a characteristic sewer odor.The biological method is designed to remove organic matter by forced aeration by colonies of aerobic microorganisms at a high level of oxygen saturation of wastewater.

Biotreatment stations are used:

• with a high level of groundwater;
• with low water resistance of the soil.

Installation locations:

• country houses;
• roadside cafes;
• baths and saunas;
• small cottage and country settlements;
• small airports;
• recreation centers;
• warehouses.

Process technology

A variety of microorganisms - bacteria, viruses, algae, fungi, protozoa, etc. - feed and receive energy from organic compounds contained in wastewater. Thus, they break down organic matter into simple elements - methane, water, carbon dioxide, hydrogen sulfide.

In a nutrient medium, colonies of microorganisms grow and self-renew, and in the case of an excess of “food”, they multiply beyond the norm. When they die, they sink to the bottom and, together with the excess, are removed from the tank.

Thus, the main component of biological treatment is the specific biocenosis of microorganisms that process pollution.

To increase the activity of processing, a number of conditions are required:

• absence/presence of oxygen;
• a certain temperature level;
• acid-base balance.

Bacteria are used in SBO:

• aerobic;
• anaerobic.

Their main types and characteristics are presented in the table:

	Aerobic	Anaerobic
The need for oxygen for life	required	not required
Life temperature range, deg.	9 - 29	9 - 37
Acid-base balance, pH	5,0 - 7,0	6,0 - 8,0
Types of bacteria	pseudomonas (80% activated sludge) - process alcohols, fatty acids, aromatic carbohydrates, paraffins and other organic substances;	hydrolytics (the first stage of methanogenesis) - break down proteins, fats, cellulose compounds, starch to form glycerol, fatty acids, amino acids, peptides, mono- and disaccharides;
	nitrifying - oxidize nitrogen compounds;	acidogenic (second stage of methanogenesis) - processing of intermediate products of hydrolysis by butyric, acetone-butyl, propionic, alcoholic fermentation;
	sulfur bacteria and thionic bacteria - process reduced sulfur compounds;	heteroacetogenic (the third stage of methanogenesis) - the transfer of organic acids (butyric, propionic) into acetic acid;
	filamentous - oxidize carbon compounds;	methanogenic (completion of anaerobic purification) - the formation of biogas by processing hydrogen, carbon dioxide and fumes, acetate, methylamine, methanol.
	cellulose-decomposing - process cellulose fiber.

Device

The complex includes a chain of various equipment. The final modification is determined by the needs of the customer. Regardless of the type, the composition includes several chambers or modules in which polluted effluents are neutralized. As a rule, a standard device consists of the following main components:

• reservoirs (receiving, secondary clarifier, outlet);
• well;
• distributor;
• silt accumulator;
• pumps and compressors;
• gratings are mechanical;
• biological filters;
• disinfectants;
• pipelines.

Stages of work

1. Wastewater enters the first module, which acts as a sump. There, substances with a low density form a film on the surface, and with a high density they precipitate as a precipitate.
2. Then, with the help of pumps, the initially purified liquid is fed into the second module with microorganisms, the vital activity of which is supported by the oxygen supplied by the compressor. This is where the pollutants begin to decompose.
3. In the third module, the sludge is separated from the liquid and directed to a separate collection compartment - the silt accumulator. At the same time, the purified water goes into the drainage well for use on the farm when watering plants, washing cars or filling barrels.

Advantages and features

The main advantages of SBO are:

• high level of purification up to 98%;
• the possibility of reusing water for technical needs and irrigation;
• complete elimination of unpleasant odors;
• long service life;
• installation in a territory with a high level of groundwater;
• simple maintenance;
• independence from weather and climatic conditions.

During operation, avoid contact with:

• aggressive detergents that cause the death of bacteria;
• non-degradable solid waste (mushrooms, vegetable residues).

Varieties

By degree of efficiency

1. Models of accumulative type with one filter. Effluent is collected and odors are conserved. Due to low performance, such devices are not popular among users.
2. Chamber products with several filters (or one to five). The efficiency is 9o-99%.
3. Hybrid stations combining the advantages of accumulative and chamber structures.

According to body material

1. Plastic.
2. Fiberglass.
3. Made of durable steel.
4. Concrete.

By place of installation

1. Underground - equipment is located underground.
2. Ground - a tank is installed on the surface, and pipes are laid underground.

Body Orientation

1. Vertical.
2. Horizontal.

Based on electricity

1. Volatile - with the obligatory connection of equipment to electric current networks.
2. Non-volatile - without mandatory connection to the power grid with independent movement of drains due to the slope.

Criterias of choice

Experts advise what to look for in order to avoid mistakes when choosing:

• the required degree of equipment productivity, depending on a large or small family, per person 200 liters per day;
