FIELD: complex processing of precipitates. SUBSTANCE: method involves separation of precipitates into three fractions, the process is followed by separate treatment of each phase. Initially sand component of precipitate is separated, then mud component is separated into phases, and each of it being treated separately. Precipitate is treated with sulfuric acid to prepare coagulant. Said precipitate is processed into sorbent with the help of pyrolysis and activation of precipitate. If said precipitate has high content of organic material then biological decomposition may be used. EFFECT: improves efficiency of method. 5 cl, 5 tbl
