I work in sales, and I really didn’t know that there are industry-specific water usage standards for the chlor-alkali industry Is ordinary deionized water sufficient? Resistivity is a parameter.
Test items, units, and specifications: Ca – mg/l; Mg – mg/l; Fe – mg/l; Si – mg/l; CL- – mg/l; Total alkalinity – mg/l; Total hardness – mg/l; pH value; Conductivity – us/cm. The equipment used is reverse osmosis and mixed-bed systems, similar to those used upstairs!
Pure water conductivity: ≤2μs/cm； Fe2+ ≤ 0.1 mg/L (wt) ； SiO2≤0.1mg/L ； Pressure ≥ 0.3 MPa
