What Does WAS Stand For?
WAS stands for Waste Activated Sludge
Waste Activated Sludge (WAS) refers to the residual biomass generated from the treatment of wastewater in activated sludge systems. It consists of microorganisms that have been removed from the aeration process and is typically subjected to further processing, such as dewatering or digestion, before disposal or beneficial reuse. WAS plays a crucial role in the microbial metabolism of pollutants during wastewater treatment, and its management is essential for the efficiency and sustainability of treatment facilities.
