Water Conservation Issues Related to Electrodialysis Desalination Systems

Electrodialysis desalination equipment is widely used in my country to produce softened and purified water. However, the water utilization rate of current electrodialysis systems is very low, with some systems achieving only around 40%. Using such equipment results in a significant waste of water resources. An automatic, frequent concentrated water circulation electrodialysis desalination system is developed. This system is designed with specific water utilization targets for different raw water qualities and desalination requirements, avoiding the indiscriminate discharge of concentrated water and regulating its concentration, thus greatly reducing the amount of concentrated water discharged and conserving water resources. Using this method, the electrodialysis desalination system can achieve a maximum water utilization rate of 90%.
