Abstract

PURPOSE: To treat waste soln. smoothly and inexpensively in a completely closed system and to recover gypsum of good quality efficiently, by decomposition of a portion of filtrate after separation of gypsum to N2 gas, by recovering addn. agent from a portion of waste soln. after hydrolysis, then by evaporating and drying the resulting waste soln. to form powder of N cpd., which is thermally decomposed to N2.
