1. Product flow rate and salt rejection rate were meticulously tested under these precise conditions:
Pro-SW-HR: Utilizing a feed water concentration of 32,000 ppm as NaCl, paired with a robust feed water pressure of 800 psi (5.5 MPa) and a feed water temperature held at 77°F (25°C), achieving an 8% recovery rate per each single membrane.
Pro-SW-HF: Designed for a feed water concentration of 20,000 ppm as NaCl, complemented by a feed water pressure of 800 psi and a consistent feed water temperature of 77°F (25°C), delivering an impressive 15% recovery rate per single membrane.
2. Product flow variation range is +/-20%; ensuring adaptability and performance consistency.
3. F34 features a durable fiberglass wrapped case with a mesh thickness of 34 mil. We offer additional case, mesh, and membrane element options to suit diverse needs.

a. The maximum operating temperature's relationship to pressure and pH is crucial for maintaining optimal system performance.
b. Related to the inlet water's temperature and pH, the maximum operating pressure should be considered. If the inlet water temperature exceeds 35°C and/or the pressure surpasses 69 bar, please consult with your account manager for guidance.
c. Continuous operation's pH limit is contingent upon the inlet water temperature and operating pressure, ensuring system integrity.
