Sludge is an inevitable by product of sewage treatment, and it includes pathogens, heavy
metals, organic pollutants and other toxic substances. The components of sludge are …

Environment-friendly and cost-effective disposal and reutilization of sludge wastes are
essential in wastewater treatment processes (WWTPs). Converting activated sludge into …

Large amounts of waste activated sludge (WAS) as a by-product generated from the
biological treatment in wastewater treatment plants (WWTPs) is of high moisture content …

In this work, Fe (II) catalyzing sodium percarbonate (Fe (II)/SPC) was managed to facilitate
waste activated sludge (WAS) dewatering for the first time. The results showed that after …

The ever-increasing rise in the global population coupled with rapid urbanization demands
considerable consumption of fossil fuel, food, and water. This in turn leads to energy …

The formation of refractory compounds and high nitrogen concentrations in filtrates is the
bottleneck of hydrothermal treatment (HT) for sludge deep dewatering. To simultaneously …

Dewatering of waste activated sludge (WAS) is of major interest in its volume reduction,
transportation and ultimate disposal. Persulfate-based oxidation process is a newly …

Sludge dewaterability is commonly poor due to the hydrophilic biopolymeric substances.
The highly efficient oxidation process is of great significance for extracellular biopolymers …

The disposal and resource utilization of waste activated sludge (WAS) is a big challenge for
its high moisture content. Ionic liquid (IL), 1-ethyl-3-methylimidazolium …

Zero valent iron (ZVI) activating peroxydisulfate (PDS) was demonstrated to be effective in
improving the dewaterability of anaerobically digested sludge (ADS). However, details of …
