1. The product's flow rate and salt rejection rate have been meticulously evaluated under these specific test conditions:
Pro-SW-HR: With an impressive feed water concentration of 32,000 ppm as NaCl, this system operates at a robust feed water pressure of 800 psi (5.5 MPa) and an ideal feed water temperature of 77°F (25°C). The system achieves a recovery rate of 8% for each single membrane, showcasing its efficiency.
Pro-SW-HF: Tailored for a feed water concentration of 20,000 ppm as NaCl, it also utilizes a feed water pressure of 800 psi (5.5 MPa) and maintains the optimal feed water temperature of 77°F (25°C). It boasts a recovery rate of 15% for each single membrane, highlighting its high-performance capabilities.
2. The product flow may vary within a range of +/- 20%, ensuring flexibility and adaptability to different operational requirements.
3. F34 is ingeniously designed with a fiberglass-wrapped case featuring a mesh thickness of 34 mil. Additionally, we offer a variety of case options, mesh types, and membrane elements to suit diverse needs.

a. The maximum operating temperature is intricately connected to both the operating pressure and the pH, ensuring optimal performance.
b. The maximum allowable operating pressure is contingent upon the inlet water's temperature and pH. For instances where the inlet water temperature surpasses 35°C and/or the inlet water pressure exceeds 69 bar, we advise contacting your dedicated account manager for tailored assistance.
c. The pH limit for continuous operation is directly influenced by the inlet water temperature and the operating pressure, ensuring safe and efficient functionality.
