Abstract: The present invention refers to an anaerobic process with filtration procedure for wastewater treatment at room temperature, that comprises: continuously feeding at least one anaerobic reactor, with previously sieved wastewater and feeding biodegradable organic waste—BOW—also previously sieved, said reactor being coupled to at least one gasified filtration membrane, with recirculation of biogas from the reactor, carrying out the anaerobic digestion of the organic fraction contained in the mixture of wastewater and the BOW, in the reactor, obtaining a treated mixture and filtering the mixture treated in the reactor, in at least one filtration tank through the gasified membrane under conditions such that the relationship between the biogas recirculated per square meter of membrane, and time unit, and the wastewater filtered—SGDp—is the minimum value allowed by the solid concentration in a treatment plant.
