TEST SOLUTION FOR EVALUATING MEMBRANE PERFORMANCE AND PERFORMANCE EVALUATION METHOD USING IT

摘要

PURPOSE: A test solution for evaluating membrane performance, and performance evaluation method using the same are provided to predict the durability of a purifier and early clogging in a field. CONSTITUTION: CaCl2 232.68 mg/mL, Mg(NO3)2 7.63 mg/mL, Sr(NO3)2 0.63 mg/mL, SiO2 16.02 mg/mL, NaHCO3 457.04 mg/mL, KHCO3 5.10 mg/mL, MgSO4 77.83 mg/mL, are added to pure water in a mixer. The mixture is uniformly mixed at room temperature. An artificially prepared water composite of 600ppm is fabricated. In order to evaluate membrane performance, the water composite passes through a membrane at 20~25C in pH 6.0-8.4.
