1. The product flow rate and salt rejection rate are derived from the following precise test conditions:
Pro-SW-HR: Crafted for optimal performance, this membrane uses feed water with a concentration of 32000 ppm NaCl, operating under a feed water pressure of 800 psi (5.5 MPa), and a stable feed water temperature of 77°F (25°C). Designed for efficiency, it achieves a recovery rate of 8% for each single membrane.
Pro-SW-HF: Engineered for enhanced results, this model uses feed water with a concentration of 20000 ppm NaCl, maintaining a feed water pressure of 800 psi (5.5 MPa) and a consistent feed water temperature of 77°F (25°C). It efficiently supports a recovery rate of 15% per single membrane.
2. The product flow variation range is within +/-20%, ensuring reliable performance.
3. F34 is a robust fiberglass-wrapped case featuring a mesh thickness of 34 mil. We offer additional case types, mesh, and membrane elements to cater to diverse needs.

a. The maximum operating temperature is intricately linked to both operating pressure and pH levels, ensuring optimal function.
b. The maximum operating pressure depends on the inlet water's temperature and pH. If 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 assistance.
c. The pH limit for continuous operation is associated with both the inlet water temperature and operating pressure, guaranteeing stability.
