ABSTRACT:
Waste water is subjected to electrolysis in an electrolytic cell having an anode comprising an insoluble central electrode and a body of particulate iron pieces disposed therearound and in electrical contact therewith, whereby impurities in the waste water become occluded within a floc of iron hydroxide formed by electrolytic dissolution of the iron pieces, and the floc containing the impurities is subjected to oxidation processing and is thereafter separated. A magnetic field can be applied to the waste water thus treated thereby to promote sedimentation of the floc.
