When To Use Electrodeionization Systems

Home / When To Use Electrodeionization Systems

There are options to consider when choosing a system to filter impurities out of water. When it comes to industrial, manufacturing, and processing, the choice of electrodeionization systems, EDI, and RO or reverse osmosis systems, is a consideration.

The RO and EDI Difference

Both options are ideal for water filtration, but the level of filtration required is the key differentiator for the choice of system. The electrodeionization systems are typically reserved for use when high purity water is needed, while RO systems are used when water needs to be free of dissolved materials such as heavy metals, chemicals, or even organic matter. The RO system uses a semi permeable membrane to prevent impurities from passing through, resulting in pure water leaving the system.

The EDI system also uses semi permeable membranes, but it also includes an ion exchange stage. This is accomplished by applying a low-level electric current to the resin to create an ion exchange. This removes any ionized particles from the water, offering high purity water as opposed to pure water free from dissolved solids. At the same time, the ion exchange is designed to continually regenerate the resin, providing an effective process for continuous operation with no need for shutdown.

When any operation or process requires the use of ultrapure or high purity water, electrodeionization is an effective option. It does not use harsh or caustic chemicals, it provides quality control with continuous filtration, and it can be customized to process the volume of water needed for any high purity or ultrapure process or application.
