Anaerobic digestion is a promising approach for waste activated sludge (WAS) disposal.
However, a wide range of exogenous pollutants (eg heavy metals, nanoparticles) exists in …

Humic substances (HS) is one of the main organic components of biowaste with high
molecular weight and aromaticity. There is a growing concern that HS will hinder the …

Owing to the development of urbanization, the amount of sewage sludge generated through
biological activated sludge process has increased dramatically. Anaerobic fermentation of …

Microplastics and antibiotics are emerging pollutants that inevitably enter the sludge
anaerobic digestion system. Current studies mainly focused on the individual effects of …

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

Humic-like acids (HAs) are abundant in sewage sludge but mainly bonded with solids. Thus,
their influences are often neglected in conventional digestion processes. Currently thermal …

Waste activated sludge (WAS), the major by-product of wastewater treatment plants, has
been hugely produced with the increase of wastewater treatment capacity. Anaerobic …

Anaerobic digestion (AD) is an effective approach to recovering chemical (organic) energy
from excess sludge, but the conversion efficiency for energy is usually not very high. One of …

Anaerobic digestion (AD) is a low-cost technology widely used to divert waste activated
sludge (WAS) to renewable energy production, but is generally restricted by its poor …

The methane productivity and long chain fatty acids (LCFAs) degradation capability of
unacclimatized seed sludge (USS) and acclimatized seed sludge (ASS) at different …
