Wastewater treatment plants (WWTPs) consume high amounts of energy which is mostly
purchased from the grid. During the past years, many ongoing measures have taken place …

Low cost production of volatile fatty acids (VFA) from waste by acidogenic fermentation has
drawn extensive research interests as VFA is a critical substrate for microorganisms involved …

Anaerobic digestion of waste activated sludge is frequently restricted with the slow
fermentation rate due to its complex components. Carbon materials have been reported to …

The textile industry is a substantial consumer of water and produces enormous volumes of
contaminated water; the most important contaminants are azo dyes. Microbial processes for …

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 …

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

During wastewater treatment, most organic matter is transferred to a solid phase commonly
known as sludge or biosolids. The high cost of sludge management and the growing interest …

Biosolids are the biological organic matter extracted from various treatment processes of
wastewater which are considered as a rich source of energy and nutrients. The most …

Most of the pretreatments to sewage sludge in lab-scale studies show high potentials to be
implemented in an anaerobic digester since they produce an increase in the biogas …

The disposal of excessive activated sludge by advanced oxidation processes (AOP) to avoid
its potential environmental risk has received extensive attention. As an efficient and clean …
