Organic wastewater/livestock manure/agricultural straw anaerobic fermentation tank

Stainless steel anaerobic digestion tank

Anaerobic fermentation for biogas production refers to the process in which substrates (activated sludge/kitchen waste/organic wastewater/livestock manure/agricultural straw) are decomposed into biodegradable organic matter such as carbon dioxide, methane, and water by facultative and anaerobic bacteria under anaerobic conditions, stabilizing the substrates. It is one of the commonly used methods for reducing and stabilizing substrates.
