Recovering Salts from Industrial Brines by Nf-md: Case Studies on IEX Regeneration Wastewater and Chloride Rich Wash Water from a Zinc Ore Refinery
Original language description
The possibilities for salt recovery from industrial brines by a coupled nanofiltration - membrane distillation (NF-MD) process are illustrated in this paper by two case studies i.e. the recovery of water and chloride salts from Ion Exchange (IEX) regenerate and from zinc ore refinery wastewater. Ion exchange based demineralization of tap water for the preparation of process water results in a saline regeneration wastewater. Techno-economical evaluation shows that NF-MD on this wastewater is economicallyfeasible for midsized and larger scale demineralization plants (200 to 2000 m3/day demineralized water) but only when discharge is prohibitively expensive or not allowed. Scaling is found to be a main bottleneck for NF-MD. It is therefore concluded thatfurther physicochemical pretreatment is required to improve the process. The cost benefits of water reuse (1.5% to 3.2%) and salt recuperation (0.16% to 0.36%) are small when compared to the overall treatment cost. The main benefits are
