Reducing water volume and controlling salt composition before evaporation and crystallization helps reduce the scale and operating pressure of downstream equipment.
Reduction Value
- Reduce the water volume entering the evaporation system.
- Reduce the impact of water quality fluctuations on the crystallization stage.
- Create conditions for salt separation, reuse, and solid product control.
Common Combinations
Pretreatment, membrane separation, electromembrane concentration, evaporation, and crystallization should be combined according to the specific water quality. A fixed process should not be applied to all high-salinity wastewater.
Key Boundaries
- Control of hardness, silica, and organics.
- Target concentration factor and recovery rate.
- Final destination of concentrate and crystallized salts.
