Abstract (en)
[origin: WO2011023851A1] A method and apparatus for the purification of wastewater. The hydrostatic pressure of wastewater present in a tank (14) is used for passing wastewater across an electrolytic cell submerged in the tank. The cell element equipped with an iron and/or aluminum electrode is used for generating iron and/or aluminum hydroxide working as a molecular sieve. The hydrogen released in electrolysis is used for raising the molecular sieve and impurities trapped therein up into a water and flock separation tower (7), in which the same, upon rising, accumulate for a flock (13) in an upper end of the separation tower. Purified water is removed from the separation tower (7) from below the evolving flock (13) and from above the level of water in the tank (14).
