Abstract

1464507 Clarifying effluent by cation addition VIZGEPESZETI VALLALAT 15 July 1975 29551/75 Heading C1C A process for the continuous clarification of raw water or effluent comprises adding to the raw water or effluent in a clarifier or clarifying agent as well as a salt solution containing the cation of the clarifying agent, and separating the precipitate thus formed from the at least partly clarified raw water or effluent. The presence of the clarifier's own cation influences the readiness of formation of the precipitates. The separated precipitate may be further treated by transferring it to another vessel wherein it is dissolved in an inorganic acid or alkali, and the residue is separated in a natural manner according to specific gravity by flotation and sedimentation. The precipitate may be recycled to the clarifier. Apparatus suitable for carrying out the process is also claimed.
