CSM RE2540-BLN Low Pressure Grade RO Element for Brackish Water, 2.5" x 40"
Compared to other desalination processes, the use of CSM RO Membranes shows marked improvements in performance, cost-efficiency and more convenient maintenance. However, because energy costs required for the operation of the RO system takes up a large portion of the whole maintenance fee, continued efforts are being made to relieve this burden.
One solution is CSM’s Low Pressure RO Membranes, which yields same performance rates as other regular RO membranes but requiring only two-thirds of the pressure. Therefore, RO systems installed with these membrane elements require far less in energy and relevant costs (such as part costs because the system can be simplified). Main applications are for treating brackish water.
- Each membrane element supplied with one brine seal, one interconnector (coupler) and four o-rings.
- All RE2540 elements fit nominal 2.5 inch (63.5 mm) I.D. pressure vessels.
General Features:
- Permeate flow rate: 930 GPD (3.5 m3/day)
- Nominal salt rejection: 99.2%
- Effective membrane area: 27 ft2 (2.5 m2)
