High-solid anaerobic digestion (HAD) can directly treat dewatered sewage sludge (total
solid content≥ 15%) with superior volume efficiency. Sludge stabilization during HAD is …

Extracellular polymeric substance (EPS) is key in maintaining microbial cell stability and
agglomeration in sludge, which may play as a protective layer for cells. This study tried to …

Anaerobic sludge digesters are biorefineries for energy recovery from waste activated
sludge (WAS) via methane production, in which disintegration of floc structure and microbial …

Although various pretreatments have been applied to promote the anaerobic digestion of
waste active sludge (WAS), the mechanisms regarding the impact of pretreatment on …

In decades, anaerobic fermentation with short-chain fatty acids (SCFAs) recovery from
excess sludge have attained rising attention. However, rigid particulate organic matter …

The water occurrence states in waste-activated sludge (WAS) are crucial to its dewaterability
and significantly influenced by the water-retaining capacity of extracellular polymeric …

A sludge structure perspective of the effects of humic matter (HM) on the anaerobic digestion
(AD) of sewage sludge was proposed and investigated in this study. It was observed that the …

Performance of co-digesters, treated of sewage sludge (SS) with fat, oil and grease (FOG),
were conducted semi-continuously in two mesophilic reactors over 180 days. Compared …

Using Fourier transform-ion cyclotron resonance mass spectrometry (FT-ICR MS) and
molecular reaction network analysis, this study investigated molecular transformation of …

Anaerobic granular sludge (AGS) is a promising technology for organic wastewater
treatment and energy recovery. In this study, three different kinds of Fe and Fe oxides …
