Anaerobic process with filtration procedure for treating wastewater at room temperature

The process enhances sustainable water treatment at ambient temperature. It comprises continuously feeding an anaerobic reactor with sieved wastewater and organic waste, which undergo anaerobic digestion, obtaining a treated mixture and biogas. The reactor is coupled to a gasified filtration membrane and gas is recirculated. With the method and the installation described an improvement of the chemical and energy efficiency has been achieved as well as a reduction of sludge and gaining process stability.
