Abstract
The feed water for a reverse osmosis device (7) is treated, by means of ozone, by being passed through a mixing vessel (4), in which the charging with ozone is carried out, a direct contact time container (5), and a residual-ozone destruction vessel (6) into the reverse osmosis device (7). At the permeate outlet (9) of the latter, part of the stream is branched off and fed, for charging with ozone, into an electrolysis cell (2) which is provided with a solid electrolyte, and fed back into the mixing vessel (4).
