1. Product flow rate and salt rejection rate were meticulously assessed based on the following stringent test conditions:
Pro-SW-HR: Feed water concentration set at 32,000 ppm as NaCl, operating under a robust feed water pressure of 800 psi (5.5 MPa), and a controlled feed water temperature of 77 °F (25 °C). Experience an impressive recovery rate of 8% for each single membrane.
Pro-SW-HF: Feed water concentration defined at 20,000 ppm as NaCl, also utilizing a feed water pressure of 800 psi (5.5 MPa) and a stable feed water temperature of 77 °F (25 °C). Achieve a remarkable recovery rate of 15% for each single membrane.
2. Product flow variation range is within +/- 20%, ensuring consistent performance and reliability.
3. F34 features a robust fiberglass wrapped case with a mesh thickness of 34 mil. We offer additional variations of cases, mesh, and membrane elements to cater to diverse needs.
