In today's industrial and living fields with increasingly stringent requirements for water quality, electrodeionization systems have shown wide applicability with their unique advantages.
In the power industry, the application effect of electrodeionization systems is remarkable. In the past, the operating costs of water treatment units in the power industry accounted for about 10% of the electricity cost. After using electrodeionization instead of ion exchange resin, the cost of treating 1,000 gallons of water has dropped significantly. It can effectively remove ionic impurities in water, ensure the normal operation of power generation equipment, and improve the safety and stability of power production.
The pharmaceutical industry also has certain requirements for water quality. The electrodeionization system has the characteristics of desalination and control of microbial indicators. Many companies use RO/EDI integrated systems. The system is continuously monitored by computers throughout the process, and fully automatic operation is unattended to ensure the quality of medicinal water and meet the strict requirements of drug production.
The electronics industry has extremely high requirements for water quality, and the water resistivity must be stable and greater than 18MΩ. Although the EDI effluent is around 15 - 17MΩ, the EDI + polishing resin system (ion exchange after EDI) can reduce the regeneration frequency of the polishing resin and the cost of water treatment on the basis of removing most ions, thus meeting the demand of the electronics industry for high-quality water.
In addition, in the field of electroplating and metal surface treatment, electrodeionization can be used for electroplating wastewater treatment to achieve water reuse and recover heavy metal ions.
In other fields such as the food industry and the chemical industry, the electrodeionization system also plays an important role. It is suitable for various industrial productions with high requirements for water quality, and can also be used in some scenarios that pursue the quality of domestic water. In short, the wide application of electrodeionization systems provides stable and reliable high-quality water treatment solutions for many industries.
