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 in the document has been tested and is reliable, yet variations due to different testing methods and operating conditions can occur. Therefore, users should combine these insights with practical applications and thoroughly understand the products of Ningbo Shuiyi Membrane Technology Development Co., Ltd.
