Biological wastewater treatment using “Plato” technology

We offer wastewater treatment using “PLATON” technology, which allows us to develop wastewater treatment plants of any capacity, depending on your needs. We have a whole range of “PLATON” type facilities and have accumulated extensive experience in the design, manufacture, installation and operation of various types of treatment facilities. In each specific case, the optimal model is selected that is best suited for the Customer’s facility.

What is “biological wastewater treatment”:

• 🔹 biological treatment is the most economical method of removing biodegradable pollutants from wastewater;
• 🔹 such treatment can be applied to a wide range of wastewater (domestic, industrial, etc.);
• 🔹 the treatment process is automated;
• 🔹 treated wastewater can be reused using tertiary processes (for example, using biostavka);

Field of application:

• 🔹 Urban wastewater
• 🔹 Domestic and similar wastewater generated from cottage villages, hotels and municipal facilities (hospitals, kindergartens, schools, health complexes, etc.)
• 🔹 Wastewater from the food industry and domestic wastewater from enterprises
• 🔹 Wastewater from catering establishments (cafes, restaurants, etc.)

Introduction to the technology

The removal of biodegradable organic matter, as well as nitrogen and phosphorus by biological decomposition is the most economical and simple method of wastewater treatment 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 nutrition and ensuring their own growth and reproduction. In addition to organic matter, microorganisms need trace elements (mainly nitrogen and phosphorus), the excess of which is also contained in wastewater. The main link in the treatment facilities, where microorganisms are placed and the biological treatment process takes place, is a bioreactor. Subsequently, after treatment, the water is discharged 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 processes. In modern bioreactors, both of these processes are often carried out, separated in space or time. The design of a bioreactor consists in the optimal selection and arrangement of biological processes occurring in it.

The set of microorganisms in a bioreactor is very diverse and rich. The diversity of species of organisms and their composition depends on the properties of the wastewater being treated 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 related to the possibility of biodegradation (decomposition) of pollutants and the presence of biocides (substances that inhibit (slow down) biological processes and the growth of microorganisms) in wastewater.
