How to reduce failures in chemical ultra-pure water treatment equipment

Thread Content

　　1. Design the reverse osmosis system based on a comprehensive analysis of water quality; 2. Determine the SDI value of the RO feedwater before designing the system; 3. If the quality of the feedwater changes, corresponding design adjustments must be made; 4. Sufficient pre-treatment is essential; 5. Choose the appropriate membrane elements – cellulose acetate membranes or membranes with low contamination levels may be more suitable for treating complex surface waters or wastewater; 6. Select a conservative water flux value; 7. Choose a reasonable water recovery rate; 8. Design appropriate values for cross-flow velocity and concentrate flow velocity; 9. Standardize the operational data. 　　That’s all for the introduction on how to reduce failures in industrial pure water equipment. Reducing such failures helps to protect the equipment and extend its operational life. By understanding the reasons behind the shortened lifespan of the reverse osmosis membranes in ultra-pure water equipment, it is possible to extend the equipment’s service life.
