Quantification of polyhydroxyalkanoate accumulated in waste activated sludge
Water Research, 2022 Polyhydroxyalkanoate accumulation experiments at pilot scale were performed with fullscale municipal waste activated sludge. Development of biomass PHA content was quantified by thermogravimetric analysis. Over 48 h the biomass reached up to 0.49 ± 0.03 gPHA/gVSS (n=4).

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 ...
