Abstract

Wastewater is treated in a vessel (14) supported and partly submerged in the wastewater. A proton exchange membrane (PEM) (38) divides an internal cavity inside the vessel (14) into an anode chamber (32) and a cathode chamber (34) with an anode (36) supported in the anode chamber (32) and a cathode (40) supported in the cathode chamber (34). A first aperture (22) is opened in the vessel's walls (20) to allow wastewater to flow into the anode chamber (32), where organic material in the wastewater is oxidised by microbial action, forming CO2, electrons and protons. The CO2 formed in the anode chamber (32) is released, the protons pass through the PEM (38) to the cathode chamber (34), and the electrons are conducted from the anode (36) to the cathode (40). The electrons and protons are combined in the cathode chamber (34) with oxygen in the wastewater, to form water.
