1. The product's impressive flow rate and salt rejection efficiency are derived under these specific test conditions:
Pro-SW-HR: Tested with a feed water concentration of 32,000 ppm as NaCl, maintaining a robust feed water pressure of 800 psi (5.5 MPa), at a precise temperature of 77 ° F (25 ° C), achieving a notable recovery rate of 8% for each single membrane.
Pro-SW-HF: Conducted at a feed water concentration of 20,000 ppm as NaCl, with the same rigorous feed water pressure of 800 psi (5.5 MPa), and a controlled temperature of 77 ° F (25 ° C), resulting in an impressive recovery rate of 15% for each single membrane.
2. Product flow consistency maintains within a variation range of +/-20%; ensuring reliability.
3. The F34 model features a robust fiberglass wrapped case with a mesh thickness of 34 mil. Additional case, mesh, and membrane element options are available to suit diverse needs.

a. The maximum operating temperature is intricately linked to both the operating pressure and pH levels, ensuring optimal performance.
b. Similarly, the maximum operating pressure is dependent on the temperature and pH of the inlet water. If the inlet water temperature exceeds 35°C or the inlet water pressure surpasses 69 bar, kindly consult your dedicated account manager for further assistance.
c. Continuous operation pH limits are determined by both the inlet water temperature and operating pressure, ensuring stability.
