Process for disposal of sulfate containing brines from diaphragm cell caustic evaporator systems |
摘要 |
Disposal of effluent solutions containing sodium sulfate in an ecologically safe and economically sound manner is accomplished in a process which admixes the effluent with the aqueous solution used as the mining solution in salt deposits. The effluent-containing mining solution is injected into the brine well to dissolve sodium chloride while inhibiting the dissolution of soluble calcium compounds. Brine recovered from the wells has a reduced concentration of dissolved calcium.
