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 ...

CO-conditioning and dewatering of chemical sludge and waste activated sludge [PDF]
Water Research, 2001 The conditioning and dewatering behaviors of chemical and waste activated sludges from a tannery were studied. Capillary suction time (CST), specific resistance to filtration (SRF), and bound water content were used to evaluate the sludge dewatering behaviors. Zeta potentials were also measured. Experiments were conducted on each sludge conditioned and
