RECOVERY OF PRECIPITATED CALCIUM CARBONATE AND SODIUM HYPOCHLORITE FROM THE CALCIUM HYPOCHLORITE WASTE LIQUOR GENERATE FROM CAUSTLE-SODA CHLORINE PLANT

摘要

A process whereby a waste material, hitherto drained is converted to two value added and very pure products viz., precipitated calcium carbonate meeting the straight quality prescribed by indian standard and sodium hypochlorite which is highly stable. The reaction conditions and the quantity of reagents are so adjusted that sodium hypochlorite obtained has the same chlorine contract as the original calcium hypochlorite. Further chlorination of this liquor is also possible to increase the chlorine content by further chlorination.
