1. Product flow rate and salt rejection rate were meticulously determined based on specific test conditions, ensuring optimal performance and reliability:
Pro-SW-HR: Feed water concentration was set at 32,000 ppm as NaCl, with a feed water pressure of 800 psi (5.5 MPa). The feed water temperature was maintained at a consistent 77 °F (25 °C), and a recovery rate of 8% was achieved for each single membrane, showcasing its efficiency.
Pro-SW-HF: Operating under a feed water concentration of 20,000 ppm as NaCl, the system also maintained a feed water pressure of 800 psi (5.5 MPa). With the feed water temperature held at 77 °F (25 °C), it achieved an impressive recovery rate of 15% for each single membrane, highlighting its superior performance.
2. The variation range of product flow is +/-20%, ensuring adaptability and resilience in varying operational conditions.
3. The F34 model features a robust fiberglass wrapped case with a mesh thickness of 34 mil. We offer additional types of cases, meshes, and membrane elements to cater to diverse needs and applications.

a. The maximum operating temperature is intricately linked to the operating pressure and pH levels, requiring careful monitoring.
b. The maximum operating pressure is directly correlated with the inlet water's temperature and pH. Should the inlet water temperature exceed 35°C and/or pressure surpass 69 bar, we recommend consulting with your account manager.
c. The pH limit for continuous operation is dependent on the inlet water temperature and the operating pressure, necessitating vigilant oversight.
