BIO-ELECTROCHEMICAL SYSTEM FOR RECOVERY OF COMPONENTS AND/OR GENERATING ELECTRICAL ENERGY FROM A WASTE STREAM AND METHOD THERE FOR

摘要

The invention relates to a bio-electrochemical system (2) and method for recovery of components or generating electrical energy from a waste stream. The system according to the invention comprises: • - an anode compartment (6) with an anode (8); • - a cathode compartment with (12) a cathode (14), wherein at least one of the anode and cathode is a bio-electrode; • - a circuit (16) connecting the anode and the cathode, the circuit comprising a power source (18a) for providing an electric current or a resistor; • - an ion-exchange membrane (20) separating the anode and cathode compartment; and • - a flow channel (24) defining hydrophobic membrane (22) configured for gas extracting and/or reactant supply.
