How does MLSS affect the efficiency of biological treatment?

MLSS plays a critical role in determining the efficiency of biological treatment in wastewater systems. The concentration of MLSS in effluent treatment plant affects the microbial population responsible for breaking down organic matter. If MLSS levels are too low, treatment efficiency drops due to insufficient biomass. Conversely, excessively high MLSS can cause poor oxygen transfer and settling issues. Maintaining the optimal MLSS range ensures effective degradation of pollutants, better sludge settling, and compliance with environmental discharge norms, making the process efficient and reliable.
