How do you maintain a healthy MLSS level in an STP plant?

Maintaining a healthy MLSS level in an STP plant requires continuous monitoring and adjustment of several factors. Regular checks on the inflow characteristics, such as organic load and wastewater composition, help determine the appropriate MLSS concentration. The activated sludge process should be optimized, ensuring proper aeration and adequate retention time. By controlling the sludge age and managing the waste sludge removal, operators can maintain the ideal MLSS in STP plant, ensuring effective treatment and high-quality effluent.
