ABSTRACT:
An electroflotation device for treating contaminated water includes cathode electrodes which are self-cleaning with respect to lime deposits. Each anode electrode of the device is associated with a pair of cathode electrodes. During operation of the device, a negative potential is applied to only one of the two electrodes of each cathode pair, while the other electrode has either a zero potential or a weak positive potential applied thereto. The lime deposit formed on the non-negative electrode is dissolved by the action of the carbonic acid which is present in the water, through the formation of bicarbonates.
