1. Our product's flow rate and salt rejection capabilities have been meticulously determined under the following test conditions:
Pro-SW-HR: Conducted with a feed water concentration of 32,000 ppm NaCl, our system operates at a pressure of 800 psi (5.5 MPa) and a temperature of 77°F (25°C), achieving an 8% recovery rate per single membrane.
Pro-SW-HF: Tested with a feed water concentration of 20,000 ppm NaCl, maintaining a pressure of 800 psi (5.5 MPa) at a temperature of 77°F (25°C), this model boasts a 15% recovery rate per single membrane.
2. The product flow exhibits a dynamic variation range of +/- 20%, adapting seamlessly to different conditions.
3. F34 comprises a robust fiberglass wrapped case with a mesh thickness of 34 mil. We offer additional case types, meshes, and membrane elements to suit diverse requirements.

a. The maximum permissible operating temperature is intrinsically linked to both the operating pressure and the pH levels.
b. The utmost operating pressure is dependent on the inlet water's temperature and pH. Should the inlet water temperature exceed 35°C or the pressure surpass 69 bar, please reach out to your dedicated account manager.
c. The continuous operation's pH limit is intricately connected to the inlet water's temperature and the operating pressure.
