Shuiyi Resalt® Series Reclaimed Water Reuse Reverse Osmosis Membrane Products
Shuiyi Resalt® series reclaimed water reuse reverse osmosis membrane products include RBW-FR and RBW-FRLE models, characterized by their pollution resistance, high desalination, and high water production, suitable for highly polluted water sources. RBW-FR reverse osmosis membrane, characterized by stable desalination rates, high pollution resistance, and high recovery after cleaning, suitable for a wide range of applications. RBW-FRLE reverse osmosis membrane, noted for its low energy consumption and stable water production quality, particularly suitable for inlet water with a salinity of less than 2000 mg/L.
Description
- Easily restorable cleaning
Short-path, wide-channel element structure clears pollutants with a single flush. - Low cleaning frequency
Cyclean modification technology, resistant to fouling, requiring less frequent cleaning and offering a longer lifespan. - Low-energy operation
Operate at low pressure, reducing energy consumption by 20% compared to conventional products

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.
