High Pressure Resistant Spiral-wound Membrane

The chemical property of membrane and structural material of membrane element in the products of HP Series are suitable for the application of the terminal wastewater treatment, for example the COD and TDS contents of continuous decreasing the discharge of the second and third wastewater treatment. HP-RO membrane element is designed for the relatively high contents of suspended solid. HP-NF membrane element is designed for the water quality of high TDS and COD. In addition, HP-RO could be used in the high concentration of salts.

·  After operating for 24 hours, measure the average rate of desalination. Fluctuation range of flow for a single membrane element is +25%/-25%.

·  Measure Condition 1: NaCl solution of 2,000 ppm, 225psi of operating pressure, 25℃ of temperature, pH7and 15% of recovery rate.

·  Measure Condition 2: MgSO4 solution of 2,000 ppm, 110psi of operating pressure, 25℃ of temperature, pH7.5and 15% of recovery rate.
