Hydrothermal carbonization is an important thermochemical conversion process that can be
used as an energy-efficient alternative to enhance the dewaterability of sewage sludge and …

With the quick increase in industrialization and urbanization, a mass of sludge has been
produced on the account of increased wastewater treatment facilities. Sewage sludge (SS) …

With increasing energy and resource consumption due to population growth, the biorefinery
concept is becoming popular. This concept aims to harness all the properties of biomass by …

High-solid anaerobic digestion (HSAD) of sewage sludge is a promising alternative to
conventional anaerobic digestion (AD) as it reduces treatment volumes, transportation costs …

Anaerobic Digestion (AD) is used worldwide for treating organic waste and wastewater.
Biogas produced can be converted using conventional energy conversion devices to …

Sludge management is still one of the most challenging issues in wastewater treatment
plants due to a dramatic increase in sludge production, high sludge disposal costs, legal …

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 …

Anaerobic digestion of sludge not only decreases the mass/volume of sludge, but also
increases the production of energy-rich biogas. The effects of a thermal hydrolysis process …

Focus is placed on substrate pre-treatment in anaerobic digestion (AD) as a means of
increasing biogas yields using today's diversified substrate sources. Current pre-treatment …
