1. The product flow rate and salt rejection rate are determined under the following precise test conditions:
Feed water concentration: 2000 ppm as NaCl, Feed water pressure: 225 psi (1.55 MPa), Feed water temperature: 77 °F (25 °C), Recovery rate: 15%
2. Product flow variation range: +/- 15%
3. The F32 model boasts a fiberglass-wrapped case with a robust 32-mil mesh thickness. We also offer additional case types, mesh varieties, and membrane elements.
