Activated sludge process is a biological wastewater treatment process that uses microorganisms, including bacteria, fungi, and protozoa, to speed up decomposition of organic matter. Activated sludge is an aerobic process requiring oxygen for treatment. As the microorganisms grow and reproduce, waste materials are removed.

Although the activated sludge process was originally developed for treatment of domestic wastewater, it has been successfully used to treat industrial wastewater. CES can provide lagoon or tank-based activated sludge systems in a variety of configurations custom-engineered to the application in many industries. including:
