Pre-treatments for waste activated sludge (WAS) are, in most cases, an attempt to increase
the biodegradation and/or improve hydrolysis rate of WAS after anaerobic digestion. This …

Ensuring safe and effective water treatment, distribution, and reuse requires robust methods
for characterizing and monitoring waterborne microbes. Methods widely used today can be …

Chemical sulfidation has been considered as an effective strategy to improve the reactivity of
zero-valent iron (S-ZVI). However, sulfidation is a widespread biogeochemical process in …

Tire wear particles (TWPs) have been recognized as one of the major sources of
microplastics (MPs), however, effects of initial properties and photochemical behavior of …

Excess sludge production in wastewater treatment plants has become an enormous
environmental issue worldwide mainly due to the increased efforts towards wastewater …

Sludge reduction via microbial metabolism does not require extra energy and resource
inputs and thus merits attention as an alternative approach for sustainable wastewater …

Abstract Effects of ultrasonic pretreatment and packing carriers on sludge reduction,
settleability, dewaterability and microbial community structure in the anaerobic side-stream …

The sludge in situ reduction process by inserting an anaerobic side-stream reactor (ASSR)
in a sludge return line provides a cost-effective approach to reduce sludge production in …

Extracellular polymeric substances (EPS) are a major component of biofilms that act as a gel-
like matrix, binding the cells together to form their three-dimensional structure. The effects of …

Sulfur-oxidizing bacteria (SOB) can drive a high level of autotrophic denitrification (AD)
activity with thiosulfate (S 2 O 3 2−) as the electron donor. However, the slow growth of SOB …
