WATER CLARIFYING MATERIAL AND MANUFACTURING METHOD OF WATER CLARIFYING MATERIAL

摘要: PROBLEM TO BE SOLVED: To provide a water clarifying material which can maintain sound bulk structure even when thermal treatment is performed by using calcareous consisting mainly of calcium carbonate phase such as limestone raw instead quick lime and slaked lime. SOLUTION: The for waste domestic business drainage in an occlusive area pond inner bay be obtained pulverizing/mixing mixture composed essentially carbonate, siliceous silica plastic clay mineral, molding the pulverized to moldings porous then subjecting at temperature range between 750°C 1000°C convert components lime, adding after conversion carry out digestion performing steam curing 160°C 210°C digestion.
