1. The product flow rate and salt rejection rate are determined under specific test conditions:
Pro-SW-HR: Test conditions include a feed water concentration of 32,000 ppm as NaCl, a feed water pressure of 800 psi (5.5 MPa), and a feed water temperature of 77 °F (25 °C). The system achieves a recovery rate of 8% per single membrane.
Pro-SW-HF: Test conditions include a feed water concentration of 20,000 ppm as NaCl, a feed water pressure of 800 psi (5.5 MPa), and a feed water temperature of 77 °F (25 °C). The system achieves a recovery rate of 15% per single membrane.
2. The product flow may vary within a range of +/- 20%;
3. The F34 is a fiberglass-wrapped case with a mesh thickness of 34 mil. We offer additional types of cases, mesh, and membrane elements to suit diverse needs.
