1. The product's flow rate and salt rejection rate are meticulously assessed based on the specified test conditions:
Pro-SW-HR: Evaluated under test conditions of feed water concentration at 32,000 ppm as NaCl, with an impressive feed water pressure of 800 psi (5.5 MPa) and a controlled feed water temperature of 77°F (25°C), achieving a recovery rate of 8% for each single membrane.
Pro-SW-HF: Performance based on feed water concentration of 20,000 ppm as NaCl, maintaining the same substantial feed water pressure of 800 psi (5.5 MPa) at 77°F (25°C), with an optimized recovery rate of 15% for each single membrane.
2. The variation range of product flow is maintained at a practical +/- 20%, ensuring flexible operational capabilities.
3. F34 represents a robust fiberglass wrapped case featuring a mesh thickness of 34 mil. We offer additional types of cases, meshes, and membrane elements to cater to diverse needs.

a. The maximum operating temperature is intricately linked to the operating pressure and pH, ensuring optimal functionality.
b. Maximum operating pressure is contingent on the temperature and pH of the inlet water. Should the inlet water temperature exceed 35°C and/or pressure surpass 69 bar, please consult your dedicated account manager for guidance.
c. The pH limit for continuous operation is determined by the inlet water temperature and operating pressure, allowing for seamless integration.
