1. Our product's flow rate and salt rejection efficiency are derived from the meticulously controlled test conditions outlined below:
Pro-SW-HR: Feed water concentration at a robust 32,000 ppm NaCl, applying a feed water pressure of 800 psi (5.5 MPa). The feed water is maintained at an ideal temperature of 77 °F (25 °C), with a recovery rate of 8% for each single membrane.
Pro-SW-HF: Feed water concentration at 20,000 ppm NaCl, applying a consistent feed water pressure of 800 psi (5.5 MPa) and a temperature of 77 °F (25 °C), facilitating a recovery rate of 15% for each single membrane.
2. The product flow features an adaptable range of +/-20%, providing flexibility in various operating conditions.
3. The F34 model showcases a durable fiberglass-wrapped case with a mesh thickness of 34 mil. We also offer a variety of cases, mesh, and membrane elements tailored to diverse needs.

a. The maximum operating temperature is intricately linked to both the operating pressure and the pH of the system.
b. The pinnacle of operating pressure is contingent upon both the temperature and pH of the incoming water. If the inlet water temperature surpasses 35°C or the inlet water pressure exceeds 69 bar, please consult your dedicated account manager for guidance.
c. The continuous operation pH limit is determined by the inlet water temperature and corresponding operating pressure.
