Aquacenter offers a wide range of biological wastewater treatment plants. We have accumulated extensive experience in the design, manufacture, installation and operation of various types of treatment facilities. Based on this experience, we have developed a model range of “Platon” type structures. In each specific case, the optimal model is selected that is best suited for the Customer’s facility.

Introduction to technology
The removal of biodegradable organic matter, as well as nitrogen and phosphorus, by biodegradation is the most economical and simple way to treat wastewater, and is widely used in municipal services.
Biological wastewater treatment is based on the ability of microorganisms to decompose organic matter present in wastewater, using it for their own nutrition and to ensure their own growth and reproduction. In addition to organic matter, microorganisms need trace elements (mainly nitrogen and phosphorus), which are also found in excess in wastewater. The main link of the treatment facilities, where microorganisms are located and the process of biological treatment takes place, is a bioreactor. Subsequently, after cleaning, the water is removed from the facilities, and the microorganisms remain in the bioreactor. Thus, microorganisms are responsible for the removal of organic substances present in water, both in solid (in the form of suspended particles) particles and in dissolved form. There are aerobic (in the presence of air supplied to the bioreactor) and anaerobic (without air supply) purification process. In bioreactors of the modern type, both of these processes are often carried out, separated in space or time. The design of a bioreactor lies in the optimal choice and arrangement of biological processes occurring in it.
The set of microorganisms in the bioreactor is very diverse and rich. The variety of species of organisms and their composition depends on the properties of the treated wastewater and the conditions of the technological process. In other words, a kind of ecosystem is formed in the bioreactor, which continuously adapts to changing external conditions.
The limitations of this type of treatment are associated with the possibility of biodegradation (decomposition) of pollutants and the presence of biocides in wastewater (substances that inhibit (slow down) biological processes and the growth of microorganisms).
