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 …

Bioenergy, derived from biomass and/or biological (or biomass-derived) waste residues, has
been acknowledged as a sustainable and clean burning source of renewable energy with …

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 …

Currently, sludge is not considered as a waste any more, since it is capable of producing
valuable products. Besides land disposal and thermochemical processes (ie pyrolysis …

Mature landfill leachate is a refractory organic wastewater, and needs physical and chemical
pretreatments contemporaneously, eg iron-carbon micro-electrolysis (IC-ME). In this study, a …

The mechanism of Fe (II)–oxone conditioning to improve sludge dewaterability was
investigated in this study. Five different types of sludge were tested, including raw sludge …

Proteins are the dominant organic component of extracellular polymeric substances (EPS) in
waste activated sludge (WAS), and play an important role during sludge dewatering …

In this study, Fe 2+ activated-PAA was developed as a novel technology to enhance sludge
dewatering. The result showed that the filterability (CST 0/CST) enhanced by 4.20±0.14 …

As the protonated form of nitrite, free nitrous acid (FNA) is a renewable chemical that can be
produced on site from the anaerobic digestion liquor by nitritation, and has been widely …

In this study, zero valent iron (ZVI) activated peroxymonosulfate (PMS) as novel technique
(ie ZVI-PMS technology) was employed to enhance sludge dewatering. In optimal sludge …
