Abstract (en)
[origin: WO2020053063A1] The present document describes a cleaning apparatus (1) and a method for cleaning wastewater (2) from a tank (3) and/or a collection device (3a). The cleaning apparatus has at least one electrolysis cell which at least comprises an electrode space (5) with an anode (6), suitable for generating hydroxide radicals, and a cathode (7) suitable for the reduction of oxygen, which is designed as a gas diffusion electrode, a wastewater inflow line (8) and a wastewater outflow line (9) for the cleaned wastewater (10), further comprising a gas space (11) which is separated from the electrode space (5) by the cathode (7), at least one inflow line (12) and one outflow line (13) for an oxygen-containing gas, which are connected to the gas space (11), and electrical connections (19a) and (19b) which connect the anode and the cathode to a DC voltage source (19) in a switchable manner.
