Hydrodynamic Cavitation of Waste-Activated Sludge

Environmental Engineering Science, 2018
Abstract Hydrodynamic cavitation systems have shown considerable promise for wastewater treatment. These systems are also used as a sludge pretreatment device to increase treatment efficiency of anaerobic sludge digestion systems. Although there are some literature related to disintegration of waste-activated sludge by hydrodynamic cavitation, effects ...
