1. Product flow rate and salt rejection rate were meticulously determined under these specified testing conditions:
Pro-SW-HR: Utilizing feed water with a concentration of 32,000 ppm as NaCl, under a robust feed water pressure of 800 psi (5.5 MPa), and maintaining an optimal feed water temperature of 77°F (25°C), this setup achieves an impressive recovery rate of 8% for each individual membrane.
Pro-SW-HF: For this model, the feed water concentration is set at 20,000 ppm as NaCl, with a consistent feed water pressure of 800 psi (5.5 MPa). The temperature is kept at 77°F (25°C), resulting in an enhanced recovery rate of 15% for each single membrane.
2. Experience a flexible product flow with a variation range of +/-20%; offering adaptability for various operational needs.
3. The F34 model features an innovative fiberglass wrapped case boasting a mesh thickness of 34 mil. Additionally, we provide a versatile selection of alternative case types, meshes, and membrane elements to suit diverse requirements.

a. The maximum operating temperature is intrinsically linked to the operating pressure and pH levels, ensuring optimal performance.
b. Maximum operating pressure is contingent on both the inlet water's temperature and pH. For conditions where the inlet water temperature surpasses 35°C and/or the pressure exceeds 69 bar, please consult with your dedicated account manager.
c. The continuous operation's pH limit is directly associated with the inlet water temperature and operating pressure, maintaining efficiency and safety.
