Electroflocculation

Process for the purification of saline waters of industrial origin and of water/sludge mixtures using the known principles of electroflotation and flocculation. Iron, aluminium or graphite electrodes are used.

This is characterized by the fact that the water/sludge mixture, whose pH value is constantly adjusted to 3 to 10. The mixture is first mixed with compressed air, possibly enriched with ozone, or if necessary with hydrogen peroxide (H₂O₂). The mixture is then whirled from bottom to top by electrode packs mounted vertically. The purified water can flow off via an overflow device.
