After obtaining the water quality data, various aspects of it are analyzed, and on that basis an reverse osmosis system is designed. 　　2. Determine the RO feedwater SDI value before designing. 　　3. If the quality of the incoming water changes, corresponding design adjustments are required. 　　4. Sufficient preprocessing must be ensured. 　　5. Select a suitable membrane element for this device; cellulose acetate membranes or low-pollution membrane elements may be more appropriate for treating relatively complex surface water or wastewater. 　　6. When selecting water flux, try to use some commonly available data. 　　7. In terms of recovery rate, it is not necessary to focus on the exact amount; what is appropriate is sufficient. 　　8. The transverse flow velocity and the concentrated flow velocity should be as large as possible. 　　9. All data related to the entire device must be standardized.
