1. The product's flow rate and salt rejection rate are calculated under the following precise test conditions:
Pro-SW-HR: Experience optimal performance with a feed water concentration of 32,000 ppm as NaCl, at a feed water pressure of 800 psi (5.5 MPa). The feed water temperature should be 77°F (25°C), with a recovery rate of 8% for each single membrane, ensuring high efficiency.
Pro-SW-HF: Designed for superior results with a feed water concentration of 20,000 ppm as NaCl, maintaining a feed water pressure of 800 psi (5.5 MPa). Keep the feed water temperature at 77°F (25°C) for a recovery rate of 15% for each single membrane, maximizing performance.
2. Expect a variation range of product flow at +/-20%, offering flexibility in operation.
3. The F34 model features a fiberglass wrapped case with a robust mesh thickness of 34 mil. We offer additional varieties of cases, mesh, 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. The maximum operating pressure is dependent on the inlet water's temperature and pH. Should the inlet water temperature surpass 35°C and/or inlet water pressure exceed 69 bar, please reach out to your dedicated account manager for guidance.
c. The pH limit for continuous operation is associated with the inlet water temperature and operating pressure, providing a scope for adaptability.
