Abstract (en)

[origin: WO9856720A1] The invention relates to an apparatus for the electrochemical treatment of waste water by electroflocculation, comprising an electrode arrangement and an anode scraping device. The sword-shaped anode(s) (2) are flanked by cathodes (3) which have the same shape and support the support construction for the anode scraping device. The transporting of the oxide crusts scraped from the anode surface towards the lower reactor end is supported by a gas current which is introduced into the electrolysis slot through hollow sections (4) serving as distancing elements for the electrodes. The anodes can consist of several individual metal sheets having intermediate layers for lowering frictional resistance when individual sheets are advanced. The liquid tightness of the upper surface of the reactor in the area of the scraping device is ensured by a stopper of an elastic material which is not electrically conductive.
