A biological sewage treatment plant is a set of technological devices used to purify sewage. This is most often done using mechanical-chemical-biological technology. It is worth learning more about this topic and getting to know the models that work effectively.

What is a biological sewage treatment plant?
Biological sewage treatment plants are very popular, which is understandable, considering their efficiency and comfort of use. They use advanced technologies to remove solids from sewage, as well as suspensions that easily and hardly settle, or colloids. The principle of operation is very simple. The raw sewage produced is directed to a septic tank, where preliminary treatment takes place. The sewage is subjected to the action of anaerobic bacteria or aeration. The waste is decomposed. The next stage of treatment takes place in the oxygen chambers of the treatment tank. Importantly, the water obtained can be used, for example, for watering lawns or flowers. Using a biological treatment plant is really effective. There are no unpleasant odors, which appear, for example, when using a septic tank. Additionally, you can save money because it does not have to be emptied. It can be installed even on a small plot of land, regardless of the ground conditions.
Tank sizes for biological sewage treatment plants
In order to enjoy the efficient operation of the treatment plant, you must remember to choose the right size of the tank. It is estimated that in single-family homes, water consumption is about 150 liters per day. For example, a tank with a capacity of 2000 l will work very well for a family of 4. In the case of larger families, you can invest in a tank with a capacity of 5000 l. Remember, of course, that the tank should be made of a strong material that is resistant to changing weather conditions, including moisture and loads. Plastics, which are easy to transport and install, work very well here.
Construction diagram of a biological sewage treatment plant
The biological sewage treatment plant operates efficiently and does not require maintenance. It is also not susceptible to failures. Its perfection and proper construction scheme are responsible for such excellent and failure-free operation. It is made of a primary settling tank, where sewage is supplied. The first stage of purification takes place there through mechanical processes, where the sediment and scum are separated. Then the sewage is subjected to anaerobic fermentation. The products of the process are: water, carbon dioxide, and substances that fall to the bottom in the form of sediment. Another important part is the separation chamber, where the sewage mixes. It acts as a fat separator. Only then does the sewage flow to the biological reactor, where the next proper stage of purification takes place on the biological bed. Biological beds are used here, which are aerated. The next important element is the clarification chamber, where the suspensions formed after biological purification are separated. At the very end, the sewage water flows out of the treatment plant, and the resulting sludge falls from the clarification chamber to the secondary settling tank, which is the last part of the biological sewage treatment plant construction diagram.

The biological treatment plant with activated sludge in the SBR reactor, SBR MICRO-STAR Roth available in the Onninen wholesale offer, is worthy of attention. It is designed for four people. This model uses technology based on the activated sludge method. Carbon is eliminated, as well as denitrification, a chemical reaction that reduces nitrates to nitrogen. In this way, water classes C and D are obtained at the outlet.
A good choice will also be a biological treatment plant with activated sludge, SBR MS TWINBLOC Roth . This is a fully biological hybrid sewage treatment plant. It uses hybrid technology, which is a combination of a fluidized, i.e. submerged biological bed with activated sludge. This combination guarantees high treatment efficiency even with uneven sewage discharge.
Biological treatment plant with activated sludge, SBR MS TWINBLOC Roth will be a suitable choice for 7-12 users. This is another hybrid treatment plant, which is based on the activated sludge method, as well as the fixed bed. The device consists of three chambers. The first is the pre-treatment zone, the second is the biological zone with pipe aeration, and the third is the secondary treatment zone with a separator pipe.
