1. The product flow rate and salt rejection rate have been meticulously formulated based on the following advanced test conditions for optimal performance:
Pro-SW-HR: Feed water concentration of 32,000 ppm as NaCl, applied with a feed water pressure of 800 psi (5.5 MPa), at a feed water temperature of 77°F (25°C), ensuring a recovery rate of 8% per individual membrane unit.
Pro-SW-HF: Feed water concentration of 20,000 ppm as NaCl, also maintained at a feed water pressure of 800 psi (5.5 MPa) and a temperature of 77°F (25°C), achieving a superior recovery rate of 15% per single membrane.
2. Product flow variability range +/-20%, allowing flexibility for diverse operational needs.
3. The F34 model features a fiberglass wrapped case with an impressive mesh thickness of 34 mil. We offer a variety of cases, meshes, and membrane elements to meet specific requirements.

a. The maximum operating temperature intricately depends on the operational pressure and pH levels, ensuring seamless functionality.
b. The maximum operating pressure is influenced by the inlet water's temperature and pH. Should the inlet water temperature surpass 35°C or the inlet pressure exceed 69 bar, we advise consulting your dedicated account manager.
c. The pH threshold for continuous operation is contingent upon the temperature of the inlet water and the corresponding operating pressure.
