Abstract:
A method for oil-water separation of wastewater containing a surfactant and an oil content that has been emulsified by the action of said surfactant, comprising the step of:feeding the wastewater into the anode compartment of a diaphragm electrolyzer having an anode and a cathode provided in the anode compartment and a cathode compartment, respectively, which are spaced apart by a porous diaphragm and which are supplied with a dc voltage between said anode and said cathode;passing part of the wastewater feed through the diaphragm so that it enters the cathode compartment;discharging the influent from the cathode compartment; anddischarging the remainder of the wastewater feed from the anode compartment for oil-water separation.
