Abstract

PURPOSE: To effectively remove Ca and Mg from crude salt water contg. sodium bicarbonate, NaCl, Ca and Mg by adding lime and a Mg cpd. to the water in succession to form settleable flocks.
CONSTITUTION: Lime such as lime powder or milk of lime is first added to the above crude salt water, e.g. obtd. by dissolving raw salt in mother liquor free from sodium bicarbonate crystals. After adding all or the first half of the lime, a Mg cpd. such as MgCl2 is added. At this time, the amt. of all of the lime added is made 0.55W0.95 time as much as the amt. of sodium bicarbonate in the water by mol to increase flock settling speed. The amt. of the Mg cpd. used is desirable to be regulated so that the molar ratio of NaHCO3/Mg in the water becomes 5W100. By maintaining the pH of the crude salt water at 8.5W10.5 after adding the lime and then holding it at 11.0W12.5, the settleability of flocks can be enhanced furthermore.
