This article discusses the topic of sewage sludge digestion. Anaerobic digestion makes it possible to obtain biogas, which can later be used generate heat or electricity. this approach resource use is recognized worldwide as more environmentally friendly. The experience European countries in production and biogas. In Russian Federation, situation complicated by fact that wastewater contains a s...
Anaerobic digestion (AD) processes can face operational challenges or flaws such as substrate structure and characteristics complexity, process low productivity, inefficient biodegradability, poor stability, which suppresses reduces biogas biomethane production. As a result of the need to overcome these challenges/shortcomings improve enhance yield, intensification methods have gained attention...
Biogas production is rising in the context of fossil fuel decline and future circular economy, yet raw biogas requires purification steps before use. Here, we review upgrading using physical, chemical biological methods such as water scrubbing, physical absorption, pressure swing adsorption, cryogenic separation, membrane chemoautotrophic methods, photosynthetic desorption. We also discuss thei...
