Biocarriers
How does biological water and wastewater treatment with biocarriers in biobeds (MBBR) work?
Industrial and municipal treatment plants often use biological water and wastewater treatment. Wastewater needs to go through several steps in order to become clean water and one of the most important treatment steps is the degradation of organic substances by microorganisms.
Like all living things, these microorganisms need oxygen to survive and reproduce. This process takes place in aeration tanks with biocarriers (MBBR - Moving Bed Biofilm Reactor). In the aeration tank, oxygen is added to increase the growth of microorganisms. The function of the biocarriers is to provide a place for the microorganisms to grow and remain in the tank as a result of the biocarriers' large surface area, which in turn leads to an improved decomposition process of organic material. The biological carriers are in constant motion due to the air supply and water circulation in the pond or tank.
The total surface area of biocarriers varies depending on the model and size. In addition, the specific density of the biocarriers can be adjusted depending on customer-specific requirements. It is important to note that the actual density will increase as the biofilm builds on the surface of the biocarrier.
