The use of wastewater sludge as a source for energy and resource recovery is a good
alternative for its management considering the legislation requirements and the circular …

Biogas is a well-established renewable energy source produced from anaerobic digestion
(AD) of biomass/feedstock. It is probably the most versatile and efficient biofuel in terms 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 …

Agro-waste (wheat straw) is considered most effective (heating value 16 MJ/kg) for energy
recovery through anaerobic digestion (AD). However, the complex lignocellulosic structure …

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 …

Hard lignocellulosic structure of wheat straw is the main hindrance in its anaerobic
digestion. Thus, a laboratory scale batch experiment was conducted to study the effect of …

Membrane bioreactors (MBRs) have received increasing attention in the field of wastewater
treatment in recent years. However, membrane fouling is the main problem of MBRs, limiting …

The effects of binary and ternary trace elements (TEs)(Fe/Co, Fe/Ni, and Fe/Co/Ni) on the
anaerobic digestion (AD) of cattle manure were investigated using kinetic models (first …

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 …

Anaerobic digestion enables waste (water) treatment and energy production in the form of
biogas. The successful implementation of this process has lead to an increasing interest …
