In response to strong growth in energy intensive wastewater treatment, public agencies and
industry began to explore and implement measures to ensure achievement of the targets …

When properly designed, pretreatments may enhance the methane potential and/or
anaerobic digestion rate, improving digester performance. This paper aims at providing …

This paper reviews pretreatment techniques to enhance the anaerobic digestion of organic
solid waste, including mechanical, thermal, chemical and biological methods. The effects of …

This review presents the state-of-the-art sludge reduction technologies applied in both
wastewater and sludge treatment lines. They include chemical, mechanical, thermal …

Advanced oxidation processes (AOPs) are powerful methods that were traditionally used for
treatment of hazardous materials. Based on their resourcefulness, these methods have …

Many operating parameters, individually or together, may influence the performance of
anaerobic digestion towards biogas or digestate yield and quality maximization. The most …

This paper presents a review of the main sludge treatment techniques used as a
pretreatment to anaerobic digestion. These processes include biological (largely thermal …

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 …

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 …

Microalgae have been intensively studied as a source of biomass for replacing conventional
fossil fuels in the last decade. The optimization of biomass production, harvesting and …
