1. The exquisite product flow rate and salt rejection rate are derived from meticulous tests under the following conditions:
Pro-SW-HR: This involves a feed water concentration of 32,000 ppm NaCl, applying a robust feed water pressure of 800 psi (5.5 MPa), and maintaining a stable feed water temperature of 77 °F (25 °C), with an impressive recovery rate of 8% for each individual membrane.
Pro-SW-HF: Characterized by a feed water concentration of 20,000 ppm NaCl, under the same substantial feed water pressure of 800 psi (5.5 MPa) and consistent feed water temperature of 77 °F (25 °C), achieving a remarkable recovery rate of 15% for each single membrane.
2. Product flow variation range: +/- 20%; showcasing adaptability and performance stability.
3. The F34 model features a durable fiberglass wrapped case with a meticulous mesh thickness of 34 mil. Additionally, we offer a diverse range of cases, mesh, and membrane elements to meet varied needs.

a. The maximum operating temperature is intricately linked to both the operating pressure and the pH value, ensuring optimal conditions.
b. The maximum operating pressure is dependent on the temperature and pH of the inlet water. For instances where the inlet water temperature surpasses 35°C and/or the inlet water pressure exceeds 69 bar, it is advisable to contact your dedicated account manager.
c. The pH limit for continuous operation is determined by the inlet water temperature and operating pressure parameters.
