1. The product's flow rate and salt rejection capabilities are derived from our rigorous testing under these conditions:
Pro-SW-HR: Specifically tested with a feed water concentration of 32,000 ppm as NaCl, utilizing a feed water pressure of 800 psi (5.5 MPa), and maintaining a feed water temperature of 77°F (25°C). This setup achieves a recovery rate of 8% per membrane.
Pro-SW-HF: Conducted with a feed water concentration of 20,000 ppm as NaCl, at a feed water pressure of 800 psi, and a stable feed water temperature of 77°F (25°C), this membrane model attains a recovery rate of 15% per unit.
2. Our product's flow variation margin is +/-20%, ensuring consistent performance across diverse conditions.
3. Our F34 model features a fiberglass wrapped case with a robust mesh thickness of 34 mil. We also offer a variety of alternative case, mesh, and membrane element configurations to suit your specific needs.

a. The peak operating temperature is intricately linked to both the operating pressure and the pH levels, ensuring optimal performance.
b. Maximum operating pressure is contingent upon the inlet water's temperature and pH. For temperatures exceeding 35°C or pressures surpassing 69 bar, please reach out to your account manager for guidance.
c. The pH boundary for continuous operation varies with the temperature and pressure of the inlet water, crucial for maintaining system stability.
