1. The product flow rate and salt rejection rate are derived from meticulously controlled test conditions, ensuring unparalleled accuracy and reliability:
Pro-SW-HR: Feed water concentration is precisely maintained at 32,000 ppm as NaCl, under a steady feed water pressure of 800 psi (5.5 MPa). The feed water temperature is a constant 77 °F (25 °C), with an 8% recovery rate per membrane unit.
Pro-SW-HF: Feed water concentration is expertly controlled at 20,000 ppm as NaCl, with a consistent feed water pressure of 800 psi (5.5 MPa). The temperature of the feed water is a stable 77 °F (25 °C), and each membrane achieves a 15% recovery rate.
2. Product flow shows a variation range of +/-20%, accommodating diverse operational needs.
3. The F34 is a robust fiberglass-wrapped case with a durable mesh thickness of 34 mil. We offer additional case types, mesh configurations, and membrane elements to meet specific requirements.
