1. The product's flow rate and salt rejection rate were meticulously measured under the following optimal test conditions:
Pro-SW-HR: Utilizing a feed water concentration of 32,000 ppm as NaCl, this system operates with a feed water pressure of 800 psi (5.5 MPa) and a temperature of 77 °F (25 °C). It achieves an impressive recovery rate of 8% for each individual membrane.
Pro-SW-HF: Designed for a feed water concentration of 20,000 ppm as NaCl, functioning at a feed water pressure of 800 psi (5.5 MPa) and a stable temperature of 77 °F (25 °C), delivering a remarkable recovery rate of 15% per single membrane.
2. The flow variation range is +/-20%, ensuring adaptable performance across diverse conditions.
3. F34 is a robust fiberglass-wrapped case featuring a mesh thickness of 34 mil. We offer additional case types, mesh, and membrane elements to cater to varied requirements.
