Along with, or as an alternative to the aerobic biological depurative processes, specific treatments can be offered in anaerobic digestors for the stabilization of the muds produced by a depuration plant.
The anaerobic digestors realized by IDROENGINEERING are of the cylindric, gas circulation kind, and their height is contained to diminuish the environmental impact. For the biogas storage the WP gasometer of the dry, membrane kind, is proposed.
From the biogas heat and electric energy can be produced with the specific cogeneration groups (combined termic and electric energy production) with gas engines coupled with electrogenic groups.
