1. Product flow rate and salt rejection rate are determined under the following meticulously controlled test conditions:
Pro-SW-HR: With feed water concentration at 32,000 ppm of NaCl, an exerted pressure of 800 psi (5.5 MPa), maintained at a feed water temperature of 77 °F (25 °C), achieving an impressive recovery rate of 8% for each individual membrane.
Pro-SW-HF: Featuring feed water concentration at 20,000 ppm of NaCl, a sustained pressure of 800 psi (5.5 MPa), at a consistent feed water temperature of 77 °F (25 °C), attaining a remarkable recovery rate of 15% for each single membrane.
2. The flow rate of the product can vary within a range of +/-20%;
3. F34 is a robust fiberglass wrapped case, showcasing a durable mesh thickness of 34 mil. Additional options for case, mesh, and membrane element are available to meet diverse needs.

a. The upper limit for operating temperature is directly linked to the operating pressure and pH levels.
b. Maximum allowable operating pressure is contingent upon the temperature and pH of the incoming water. Should the inlet water temperature surpass 35°C and/or the inlet water pressure exceed 69 bar, kindly reach out to your account manager for guidance.
c. The permissible pH range for continuous operation correlates with the inlet water temperature and operating pressure.
