PRODUCTION AND USING METHODS OF ENVIRONMENTAL AGENTS A AND B AS FLOCCULATING AND PURIFYING MATERIAL USING MONTMORILLONITE FOR FLOCCULATING SLUDGE IN VARIOUS TYPES OF SLURRY, ADSORBING AND FLOCCULATING HEAVY METALS AND SOLID/LIQUID SEPARATING TO FORM COLORLESS CLEAR WATER

摘要

PROBLEM TO BE SOLVED: To improve performance of a flocculant for clearing slurry, to facilitate handling for multiple uses, to flocculate in a short time and to discharge clear water causing no pollution.;SOLUTION: (1) Montmorillonite, starch powder, arrowroot starch, aluminum sulfate and various types of artificial zeolite are crushed into fine powder, agitated and mixed for multiple uses, to blend and prepare the flocculating materials. (2) The agents are prepared to complete the preparation work in one work using the materials of (1) to facilitate handling. (3) Various types of artificial zeolite such as sodium type or calcium type with a cation exchanging capacity of 200 or more are used to surely eliminate heavy metals. (4) Various types of artificial zeolite such as sodium type or calcium type with a cation exchanging capacity of 200 or more are used to enhance deodorizing capacity. By using the flocculating materials, slurry can be decolorized, deodorized and cleared.;COPYRIGHT: (C)2004,JPO&NCIPI
