摘要

FIELD: water treatment. ;SUBSTANCE: method for conducting the water-chemical regime and regeneration of a baromembrane water treatment plant using a unified correction-washing composition, including ultrafiltration blocks, booster and/or main reverse osmosis blocks, using a unified correction-washing composition containing FeCl3 coagulant, NaClO (solution with a mass fraction of 50%), Na2S2O5 (solution with a mass fraction of 10%), H2SO4 (solution with a mass fraction of 92%), NaOH (solution with a mass fraction of 42%), Na5P3O10, trilon B, technical citric acid, Ecotrit® UNI 1 antiscalant, including pre-purification of the source water and chemical washing with acid and alkaline detergents, where coagulation with ferric chloride (FeCl3) is used as a pre-purification of the feed water of ultrafiltration and reverse osmosis systems; to prevent the formation of soluble forms of iron and deposits of organic compounds on the membrane surface, the pH of the source water is maintained at the level of 8.2-9.0; as an acidic detergent of ultrafiltration and reverse osmosis systems, an aqueous solution of citric acid (2200 mg/dm3) with a temperature of 35-40°C, acidified with sulfuric acid (630 mg/dm3) to pH = 2.0 is used; as an alkaline detergent of ultrafiltration systems, an aqueous solution of sodium hypochlorite (100 mg/dm3) with a temperature of 30-35°C, alkalized with sodium alkali (400 mg/dm3) to pH = 12.0; as an inhibitor of salt deposition, the anti-scalant Ecotrit® UNI 1, which does not contain phosphates, is used. ;EFFECT: creation of a universal and effective method for maintaining the WCR, which contributes to a minimum number of chemical washings by preventing deposits of membrane contamination. ;1 cl, 1 tbl, 1 ex
