Sludge theory

Webb1 maj 2024 · Waste activated sludge (WAS) is a by-product of wastewater treatment plants (WWTPs) and its efficient dewatering is a worldwide problem (Wei et al., 2024). A lower water content of dewatered sludge could reduce its volume, and further make sludge easier to be transported and disposed of (Zhen et al., 2024 ).
