METHOD OF TREATMENT OF EXCESSIVE CIRCULATING WATER OF CARDBOARD PRODUCTION FOR ITS REUSE |
摘要 |
technology of partial closed water circulation in cardboard production. SUBSTANCE: introduced successively into excessive circulating water in coagulant in form of aluminum hydroxide and chloride with aluminum oxide-chloride ratio of 0.71 to 0.92. In this case, flocculant is introduced into excessive circulating water in 30-100 s after introduction into water of coagulant. Polyacrylamide is used in form of cationic polyacrylamide with molecular weight of (5-9)106 or anionic polyacrylamide with molecular weight of (9-15)106. EFFECT: higher efficiency of method. 2 cl, 2 ex
