Note:
(1) The parameters mentioned are based on data collected after the system has been running stably for 30 minutes;
(2) Water production volume has a deviation range of ±15%;
(3) Chemical cleaning is recommended at temperatures ≤30°C, with cleaning solution pH values not exceeding 2.0-12.0 above this temperature;
(4) When running in multi-element pressure vessels, the maximum pressure drop across the vessel should be kept within 0.25 MPa, not exceeding 0.3 MPa under any circumstances.
The data presented herein are derived from specific tests and are true and reliable. However, differences may exist between test conditions and actual application environments, so actual results may vary. It is recommended that users verify and adjust according to their specific operating conditions and assume relevant responsibilities themselves.
Applications
Shuiyi Procycle® series high-pressure reverse osmosis membrane products, known for their high desalination rates, and high water production, are ideal for applications in seawater desalination and zero discharge of concentrated wastewater.
