1. The exceptional product flow rate and impressive salt rejection rate were established based on these precise test conditions:
Pro-SW-HR: Feed water held a concentration of 32000 ppm as NaCl. The feed water pressure was maintained at 800 psi (5.5 MPa), with a consistent feed water temperature of 77°F (25°C). Each single membrane achieved a recovery rate of 8%.
Pro-SW-HF: Ensuring a feed water concentration of 20000 ppm as NaCl, with a feed water pressure of 800 psi (5.5 MPa) and a stable feed water temperature of 77°F (25°C), each single membrane attained a notable recovery rate of 15%.
2. The variation range of product flow is an impressive +/-20%;
3. The F34 is ingeniously designed with a fiberglass wrapped case featuring a mesh thickness of 34 mil. We offer an extensive selection of additional cases, mesh designs, and membrane elements to suit your needs.

a. The highest permissible operating temperature is intricately linked to the operating pressure and the pH.
b. The upper limit of operating pressure is contingent upon the temperature and pH of the inlet water. Should the inlet water temperature surpass 35°C and/or the inlet water pressure exceed 69 bar, we highly recommend contacting your dedicated account manager for guidance.
c. The pH threshold for continuous operation is dependent on the inlet water's temperature and operating pressure.
