- Abstract
Biological wastewater treatment harnesses the action of bacteria and other microorganisms to clean water. Wastewater typically contains a buffet of organic matter, such as garbage, wastes, and partially digested foods. It also may contain pathogenic organisms, heavy metals, and toxins. Biological wastewater treatment involves the use of microorganisms (bacteria) to naturally degrade organic waste resulting in BOD reduction, COD reduction and wastewater odor control. The bacteria in our biological wastewater treatment products are specifically selected to handle the degradation and removal of a wide variety of wastes found in municipal wastewater, lift stations, industrial wastewater, pulp and paper wastewater, food processing wastewater, petrochemical wastewater and even animal farm wastewater. Additionally, we have special bacterial formulations to address specific needs of a wastewater treatment plant such as bulking and foaming reduction, filamentous bacteria control and phosphate reduction. Biological wastewater treatment is a process that seems simple, since it uses natural processes to help with the decomposition of organic substances, but in fact, it’s a complex process at the intersection of biology and biochemistry. The goal of biological wastewater treatment is to create a system in which the results of decomposition are easily collected for proper disposal. Biological treatment is used worldwide because it’s effective and more economical than many mechanical or chemical processes. The aim of this article is design of the automatic control for the process of biological treatment of wastewater. For realization of this point, the mathematical model and total transfer function wеrе created. By using of software MATLAB/Simulink, the dynamic simulation for the investigated biological treatment process was done.
