HCl recovery by CSRE MD in Spain

Waste water containing17-18% of HCl and 3% of FeCl 2 is generated from a metal processing plant in Barcelona. To recover and reuse HCl from waste water, CSRE MD is employed to recycle 20T/day 10-17%HCl solution utilizing 85-90℃of hot water as driving heat source. The volume of waste water is also reduced to 20% of original volume. The electricity consumption is 7-8 kWh/t.
