Septic tank Biodeka: design, installation and maintenance

Design and principle of operation of Bio Deka

An important characteristic of any type of biological septic tank is its absolute environmental safety. Before the advent of these modern high-tech devices, the neutralization of sewage was carried out using active chemical elements. However, this option was in itself unsafe, both for humans and for the environment. As a result, there was an urgent need for strict adherence to rules when handling chemicals and subsequent disposal of their reaction products; there was a huge risk of outbreaks of damage to the environment and people.

The emergence of VOCs, including Biodeka, which began to use unique cleaning methods taken from Nature itself, provided the opportunity to create an absolutely safe option for neutralizing organic waste. To effectively fulfill the assigned tasks, manufacturers used the most optimal design solutions in the production of VOCs. The design and design of the latest Biodec models take into account the main disadvantages of previous modifications and mistakes made by other manufacturers.

These biological stations are made in the form of a vertically positioned cylinder, which minimizes the destructive effect of pressure from external environments on the body. The material chosen was modern high-strength integral foam polypropylene, among whose properties the most important is its absolute neutrality to the active influences of external environments and the impossibility of oxidation. It has only one seam, which significantly reduces the risk of damage. Grousers are provided.

The internal Bio Deka tank is divided by partitions that provide a hermetically sealed separation into several compartments - “dry” and those through which treated household waste flows. Each of them carries its own functional load. Chambers in which wastewater treatment is carried out:

1. Accumulative
   , incoming wastewater. In it, primary oxidation and ammonification are carried out and a homogeneous mixture is formed; large impurities are separated when flowing through a coarse filter. This ensures a reduction in the speed of liquid movement in the septic tank, which is important to minimize the risk of leaching of activated sludge from the aeration tank.
2. Aeration chamber.
   The mixture prepared in the storage tank is fed into it using airlifts for subsequent aeration with air. Activated sludge is located here - a favorable environment for the life of microorganisms that perform the main cleaning function. Under the influence of oxygen, they actively neutralize all harmful organic substances included in sewage. Nitrification occurs.
3. Sludge stabilizer.
   The liquid redirected into it by the mamut pump is cleared of the mass of waste sludge that settles to the bottom of the chamber.
4. Secondary settling tank
   performs several important functions in a septic tank:

   — degassing of liquid;

   — separation of sludge residues from water, directed using recirculators back to the stabilizer;

   - accumulation of purified liquid to a certain volume, at which a water seal opens, leading to a gravity hole or into the drainage pump chamber in the case of a forced outlet.

The internal structure and arrangement of the chambers are slightly different for the two main types of septic tanks, which are distinguished by the method of drainage:

• Gravity



• With forced drainage.

The processes taking place in Biodeka are based on the use of active aerobic bacteria, which during their life activity destroy harmful organic substances and compounds. The treatment of household wastewater with their help is different:

• complete absence of unpleasant odors;
• high speed of neutralization;
• obtaining output water with a degree of purity reaching 98%, which allows it to be used for technical needs or as a means for irrigation;
• the possibility of using sludge in the form of waste sludge as a particularly high-quality fertilizer.

Construction of the Biodeka wastewater treatment plant

The body of the treatment plant is made of durable plastic, the internal space is divided into several chambers, each of which carries its own functional load. As a standard, the main components of Biodec VOC include:

• receiving chamber;
• aeration tank;
• stabilizer;
• secondary settling tank;
• aerator;
• airlift.

In addition, a separate compartment houses the control unit and other electronics that allow you to control the station.

Brief overview of popular models

In terms of purpose and principle of operation, all septic tanks are the same; they differ in performance, dimensions and depth of wastewater entry.

BioDeka-3 S-600

This system with minimal performance assumes up to 3 people in the house. Indicators of household waste and sewerage (bathroom) are taken into account. The system will work effectively when all three family members use the sewer system simultaneously.

The dimensions of the installation are small - up to 2 meters high, which allows you to freely dig it into the ground. The sewer pipes enter the structure at a depth of 0.6 meters, therefore, in order to install the system in regions where cold weather prevails, additional insulation of the sewer pipe in the ground is necessary.

The cleaning system has high productivity and is designed for the simultaneous use of sewerage by 8 residents. The installation showed excellent performance when working on two residential buildings at once. The biological treatment system is large in size with a sewer pipe entry depth of 1.8 meters, which makes it difficult to carry out excavation work. Widely used in northern regions with cold climates. The system is highly expensive.

There are installations designed to serve up to 20 people. They are suitable for sewer and domestic wastewater in public buildings, cafeterias, gas stations, private hotels.

Installation features

By choosing a Biodeka septic tank, each user becomes the owner of a unit, the installation and installation of which is simple and efficient. Regardless of the model, during installation it is important to strictly follow the recommendations of the manufacturer and specialists. Particular attention should be paid to the preparatory process and the sequence of steps performed.

1. The location of the septic tank is determined based on the following factors;
   — points of discharge of waste pipes from the facility

   — availability of free space;

   — organization and direction of outflow lines.

2. A pit is being prepared, the dimensions of which must exceed the dimensions of the septic tank by 30 cm, for its subsequent safe immersion.
3. The bottom of the pit is leveled using a cushion of fine sifted sand 10 cm thick. It is also necessary to prepare it for filling and compacting the lugs.
4. Discharge lines and trenches are formed for laying waste pipes.
5. The tank is installed with the obligatory subsequent filling of the gaps with sand. The backfilling process should be accompanied by constant pouring of water and compaction of each new layer.
6. Supply pipes are being cut into, connecting power supply systems, air supply systems, and installing drainage systems.
7. Upon completion of the work, the septic tank requires testing of its functioning.

Recommendations for use of various models

One of the positive aspects that influence the choice of a station of this type is the minimal labor intensity and lack of costs in their maintenance. The user is only required to comply with the manufacturer’s basic operating recommendations, for which there is no need to have professional skills and knowledge or special equipment. When using a Biodeka septic tank it is prohibited:

• throw into the drainage system objects that cannot be processed by microorganisms - rags, lids, plugs, any solid objects;
• drain chemicals harmful to the life of bacteria - petroleum products, non-food acids, alkali, chlorine.

During the entire period of use of a septic tank of any model, it is necessary to constantly monitor the quality of the resulting liquid for the appearance of odor. There should be no sediment or impurities in it.

Quarterly, but at least once every six months, it is necessary to inspect the chambers and remove the waste sludge accumulated in them. The frequency of this process depends on the load with which the septic tank has been operating during the time that has passed since the last cleaning. Sludge is pumped out using a fecal pump.

An important point is the mandatory control of the filter elements of compressor units, on which the uninterrupted operation of the unit and the duration of its operation depend. They require mandatory cleaning once every six months.

Operation and Maintenance

To ensure smooth operation of the installation, you must follow a few simple rules. These include:

1. do not allow debris to enter the tank, which could lead to blockage;
2. Do not pour substances into the unit that can lead to the death of microorganisms: chlorine-based disinfectants, antibiotics, petrochemical products.

Also, periodically, it is necessary to carry out maintenance - empty the sedimentation tanks of accumulated sludge. You can do this yourself, using a fecal or drainage pump, or contact a company that carries out such work. Cleaning is carried out no more than twice a year.

The main model range of Biodeka septic tanks

When starting to design a local sewage system, it is necessary to have a complete understanding of the model range of stations offered by the manufacturer Biodeka. This will allow you to make the most correct choice based on your existing needs, as well as most accurately determine the amount of funds required for purchase. Today, all major models are available to domestic consumers, among which the following are in particular demand:

Benefits of Bio Deca

One of the important advantages that distinguishes any septic tank from this manufacturer is the simplicity of their design. The developers tried to get rid of most of the elements that could most often fail. Among such solutions is single-mode stations. That is, any model is equipped with only one compressor unit that supplies air to all elements of the station in constant mode. As a result, it became possible to do without a large number of different sensors and devices when creating such stations, which can always fail, in order to ensure automatic and timely removal of purified water when it reaches a critical volume in the chamber. Every Biodeka septic tank makes maximum use of the basic laws of physics.

In addition, all models provide owners with a number of important user benefits:

1. The quality of wastewater treatment reaches 98%, which allows the resulting water to be used for technical needs and irrigation.
2. The high degree of reliability of septic tanks and simplicity of design are due to operation in a single mode.
3. The number of components and devices that increase the risk of disruption of functionality or failure of the station is minimized.
4. The use of modern, highly durable and climate-resistant polymer material in the manufacture of the case.
5. Thoughtful ergonomics.
6. Minimization of dimensions and weight.
7. Possibility of choosing a septic tank model with an insertion depth of up to 1800 mm.
8. Affordable price with high quality.

Considering all the features, characteristics and advantages that a septic tank from this manufacturer has, we can conclude that it performs the required functions with high quality. The practical use of VOC Biotek only confirms the high efficiency and provision of the highest possible level of treatment of domestic wastewater by stations of this type at minimal cost to the user.

Principle of operation

Septic tanks for summer cottages BioDeka is an autonomous treatment plant operating in one operating mode. The kit must include a compressor connected to the electrical network. Under its influence, the supply of the necessary supply of air and oxygen is ensured to all airlifts.

First of all, the masses enter the primary chamber (receiver), where accumulation and mixing occur. The prepared composition is averaged over the size of the suspensions. Large, insoluble fractions are screened out, which precipitate and are taken to a special receiving device. Next, the wastewater prepared for treatment enters the aeration tank, where it is mixed with activated sludge and oxygen. After purification, the water enters the sludge stabilization chamber and then into the secondary settling tank. Then the water, purified to 98%, can be discharged into the terrain or accumulated in a special container for technical needs.
