1. Product flow rate and salt rejection rate: These metrics were meticulously measured under the specific test conditions outlined below:
Pro-SW-HR: Conducted with feed water concentration at 32,000 ppm as NaCl, with a consistent feed water pressure of 800 psi (5.5 MPa), and maintained at a temperature of 77°F (25°C). Each single membrane exhibits a recovery rate of 8%.
Pro-SW-HF: Tested with feed water concentration at 20,000 ppm as NaCl, under the same feed water pressure of 800 psi (5.5 MPa), also at a temperature of 77°F (25°C). This setup achieves a recovery rate of 15% per single membrane.
2. The product flow may vary within a range of +/-20%, ensuring flexibility and adaptability in performance.
3. The F34 model features a robust fiberglass-wrapped case with a mesh thickness of 34 mil. We also offer a diverse range of cases, meshes, and membrane elements to suit your specific needs.

a. The maximum operating temperature is intricately tied to the operating pressure and pH levels, ensuring optimal performance.
b. The maximum operating pressure is influenced by temperature and pH of the inlet water. Should the inlet water temperature exceed 35°C or the inlet pressure surpass 69 bar, please reach out to your dedicated account manager for guidance.
c. The pH limit for continuous operation is dependent on the inlet water's temperature and operating pressure, maintaining operational integrity.
