Abstract
PURPOSE: To purify crude salt water by adding lime in a predetermined ratio to NaHCO3 in the water to remove Ca and Mg as settleable flocks.
CONSTITUTION: To crude salt water contg. NaHCO3, NaCl, Ca and Mg is added lime such as quick lime or slaked lime powder so that the molar ratio of Ca/ NaHCO3 in the water becomes 0.55W0.95, thereby forming settleable flocks of Ca and Mg, which are then separated and removed. By carrying out the above treatment after regulating the molar ratio of NaHCO3/Mg in the water to 5W40, esp. 7W20, the settleability of the flocks can be enhanced furthermore.
