Abstract
Calcium silicate or its components is fused and the molten compound is quenched in sea water or a solution containing magnesium salts so as to form a coating and reduce its activity. The product is dried, crushed and sized.ALSO:Fused and quenched calcium silicate is used to treat water which has been pretreated by usual methods. Chlorination, coagulation sequestering phosphating and control of pH with sulphamic acid or calcium sulphamate are described.
