Abstract

1473580 Electrolytic flotation process K XYLANDER and A MENZEL 28 June 1974 [28 June 1973 24 June 1974] 28856/74 Heading C1C [Also in Division C7] A process for purifying an aqueous liquid by flotation of suspended solids with gas bubbles produced by electrolysis between at least one pair of electrodes is characterized in that at least one of said electrodes is moved relative to said liquid in a generally horizontal direction over at least a substantial portion of its path through the liquid while said electrolysis and flotation are taking place. An apparatus is also claimed.
