1. Our product flow rate and salt rejection rate have been meticulously assessed under the following optimal test conditions:
Pro-SW-HR: With a feed water concentration of 32,000 ppm as NaCl, an operational feed water pressure of 800 psi (5.5 MPa), and a feed water temperature of 77°F (25°C), this membrane achieves a recovery rate of 8% for each single membrane.
Pro-SW-HF: Consisting of a feed water concentration of 20,000 ppm as NaCl, maintaining a feed water pressure of 800 psi (5.5 MPa), and set at a feed water temperature of 77°F (25°C), this configuration allows for a recovery rate of 15% per single membrane.
2. The range of variation for product flow stands at +/- 20%, ensuring adaptable performance across diverse conditions;
3. The F34 model features a robust fiberglass wrapped case with a mesh thickness of 34 mil. Additionally, we offer a variety of case styles, mesh options, and membrane elements tailored for your unique needs.

a. The peak operating temperature is closely associated with the specific operating pressure and pH levels, ensuring optimal performance and safety.
b. The maximum permissible operating pressure is influenced by both the temperature and the pH of the inlet water. Should the inlet water temperature surpass 35°C and/or the inlet water pressure exceed 69 bar, please reach out to your dedicated account manager for guidance.
c. The continuous operation pH limit is dependent on the inlet water temperature and operating pressure, a critical factor for maintaining operational integrity.
