Sludge disposal is an integral part of wastewater treatment systems, and its cost usually
accounts for more than half of the total operation cost. Sludge disposal technology is facing …

The increase in bacterial resistance to one or several antibiotics has become a global health
problem. Recently, nanomaterials have become a tool against multidrug-resistant bacteria …

Extracellular polymeric substances (EPS) have a significant effect on the dewaterability of
waste-activated sludge (WAS); however, the role of polarity distribution (hydrophilic …

Our previous work has reported the pretreatment of secondary sludge with free ammonia
(NH 3, FA) enhanced the methane production in batch biochemical methane potential tests …

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 …

Food waste (FW) has been considered a potential carbon reservoir and can be used for high-
value volatile fatty acid (VFA) production via anaerobic fermentation. Nevertheless, more …

Abstract Para-chloro-meta-xylenol (PCMX), as a massively used antimicrobial agent,
exhibited dose-dependent effects on the sludge fermentation for volatile fatty acids (VFAs) …

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 …

Dissolved organic matter (DOM) of sludge is a heterogeneous mixture of high to low
molecular weight organic substances which is including proteinaceous compounds …
