1. The product flow rate and salt rejection rate were determined under the following meticulously controlled test conditions:
Pro-SW-HR: With a feed water concentration of 32,000 ppm as NaCl, a feed water pressure of 800 psi (5.5 MPa), a feed water temperature of 77 °F (25 °C), and a recovery rate of 8% for each individual membrane.
Pro-SW-HF: Featuring a feed water concentration of 20,000 ppm as NaCl, a feed water pressure of 800 psi (5.5 MPa), a consistent feed water temperature of 77 °F (25 °C), and an impressive recovery rate of 15% for each single membrane.
2. The variation range of the product flow is +/-20%, ensuring flexibility and adaptability in different applications.
3. The F34 model is encased in a robust fiberglass shell with a mesh thickness of 34 mil. Additionally, we offer a diverse selection of cases, mesh designs, and membrane elements to suit your specific needs.

a. The maximum operating temperature is intricately linked to both the operating pressure and the pH levels, ensuring reliable performance.
b. The apex of operating pressure is dependent on both the temperature and pH of the inlet water. For conditions where the inlet water temperature exceeds 35°C and/or the inlet water pressure surpasses 69 bar, please reach out to your account manager for tailored guidance.
c. The pH limit for continuous operation is intricately related to the inlet water's temperature and operating pressure, ensuring consistent and optimal functionality.
