1. The flow rate and salt rejection rate of our product are meticulously determined under the following controlled test conditions:
Pro-SW-HR: At a feed water concentration of 32,000 ppm as NaCl, with a feed water pressure of 800 psi (5.5 MPa), and a feed water temperature of 77°F (25°C), the recovery rate achieves 8% for each individual membrane.
Pro-SW-HF: Operating with a feed water concentration of 20,000 ppm as NaCl, this model maintains a feed water pressure of 800 psi (5.5 MPa) and a temperature of 77°F (25°C), achieving a recovery rate of 15% for each individual membrane.
2. Please note, the flow rate variation range of our product is +/-20%;
3. The F34 model is encased in a durable fiberglass wrap with a mesh thickness of 34 mil. We offer a variety of cases, meshes, and membrane elements to suit diverse needs.

a. The maximum allowable operating temperature is dependent on both the operating pressure and the pH level.
b. The highest operating pressure is contingent upon the inlet water's temperature and pH. If the inlet water temperature exceeds 35°C or the inlet water pressure surpasses 69 bar, it's imperative to consult your account manager for guidance.
c. The permissible pH range for continuous operation is influenced by both the inlet water temperature and the operating pressure.
