PSI MEMBRANE®Pro-BW Brackish Water Membrane is a cutting-edge, third-generation nanocomposite (TFN) reverse osmosis membrane element. With its uniquely advanced anti-fouling technology, it provides exceptional anti-fouling and cleaning performance. This ensures a high salt rejection rate while significantly lowering energy consumption and extending the cleaning cycle.

1. The product flow rate and salt rejection rate were determined under the following precise test conditions:
Feed water concentration: 2000 ppm as NaCl Feed water pressure: 225 psi (1.55 MPa) Feed water temperature: 77°F (25°C) Recovery rate: 15%
2. Expect a product flow variation range of +/-15% to accommodate different operating environments.
3. The F32 model features a robust fiberglass-wrapped case with a mesh thickness of 32 mil. Additional case types, mesh options, and membrane elements are also available to meet diverse needs.
