1. Our product's flow rate and salt rejection rate were determined based on the following meticulously controlled test conditions:
Pro-SW-HR: Feed water concentration is an impressive 32,000 ppm as NaCl, with a robust feed water pressure of 800 psi (5.5 MPa). The feed water temperature is a stable 77°F (25°C), ensuring optimal conditions for performance. Each single membrane boasts a recovery rate of 8%.
Pro-SW-HF: This variant operates with a feed water concentration of 20,000 ppm as NaCl, maintaining a consistent feed water pressure of 800 psi (5.5 MPa). The feed water temperature is again 77°F (25°C), with an enhanced recovery rate of 15% per single membrane.
2. The variation range of product flow is within a precise +/-20%; ensuring consistent and reliable performance.
3. The F34 model features a robust fiberglass wrapped case with a sturdy mesh thickness of 34 mil. We offer an extensive array of additional types of cases, meshes, and membrane elements to meet diverse needs.

a. The maximum operating temperature is intricately linked to the operating pressure and the pH level, ensuring safe and efficient operation.
b. The maximum operating pressure is contingent upon the temperature and pH of the inlet water. In scenarios where the inlet water temperature surpasses 35°C and/or the inlet water pressure exceeds 69 bar, please reach out to your dedicated account manager for tailored advice.
c. The pH limit for continuous operation is influenced by the inlet water temperature and operating pressure, critical for maintaining integrity and performance.
