1. The product flow rate and salt rejection performance were meticulously evaluated under these precise test conditions:
Pro-SW-HR: Conducted with a feed water concentration of 32,000 ppm NaCl, an operational pressure of 800 psi (5.5 MPa), and a controlled temperature of 77 °F (25 °C). A recovery rate of 8% per individual membrane was achieved.
Pro-SW-HF: Utilizing a feed water concentration of 20,000 ppm NaCl, pressure sustained at 800 psi (5.5 MPa), at a temperature of 77 °F (25 °C), resulting in a 15% recovery rate for each membrane.
2. The product flow may vary within a range of +/-20%; ensuring adaptability and robust performance.
3. Our F34 model features a fiberglass encasement with a mesh thickness of 34 mil. Additional options for casing, mesh structures, and membrane elements are readily available to meet diverse needs.

a. The peak operating temperature is influenced by operating pressure and pH levels, ensuring safe and effective function.
b. The upper limit of operating pressure is contingent upon the temperature and pH of the incoming water. For scenarios where water temperature exceeds 35°C and/or pressure surpasses 69 bar, please consult with your account manager for tailored guidance.
c. Continuous operation's pH limits are dependent on inlet water temperature and operating pressure for optimal performance.
