Abstract

A method of treating sewage comprises separating solids (3) from the sewage (1), accumulating and averaging the separated sewage (5), and further subjecting averaged sewage (7) to electrochemical treatment so as to produce a foam layer (9), forming in the resulting foam layer (9) air counterflows by means of rarefaction provided by a pump (10) at the solids separation stage such that the flows of air (11) and foam are directed from the peripheral areas of the foam layer (9) towards the central portion thereof and further onto the solids separation stage, while treated liquid (14) is directed towards the area underlying the central portion of the foam layer (9) and subsequently withdrawn therefrom. <IMAGE>
