1. Product flow rate and salt rejection rate were meticulously measured under the following specific test conditions:
Pro-SW-HR: Observed with a feed water concentration of 32,000 ppm as NaCl, a robust feed water pressure of 800 psi (5.5 MPa), and a stable feed water temperature of 77°F (25°C), ensuring an 8% recovery rate per individual membrane.
Pro-SW-HF: Conducted with a feed water concentration of 20,000 ppm as NaCl, maintaining a feed water pressure of 800 psi (5.5 MPa) and a consistent feed water temperature of 77°F (25°C), achieving a 15% recovery rate per single membrane.
2. Expect a product flow variation range of +/-20%, introducing flexibility to meet diverse needs.
3. The F34 model boasts a fiberglass-wrapped case featuring a mesh thickness of 34 mil. We offer an array of alternative cases, meshes, and membrane elements to tailor to your specific requirements.

a. The maximum allowable operating temperature is intricately linked to the operating pressure and pH levels.
b. The maximum permissible operating pressure correlates with the inlet water temperature and pH. Surpassing an inlet water temperature of 35°C or an inlet water pressure of 69 bar necessitates consulting your account manager for guidance.
c. The continuous operation pH limit is contingent upon the inlet water temperature and the operating pressure.
