System Applications

System Technologies

  • Electrodeionization (EDI)


The Clearwater line of CWEDI Electrodeionization systems produce high purity water (>16 MΩ resistivity), continuously and without the use of chemical regenerants.

Systems are modular, expandable, and may be configured to suit any specific application requiring ultra pure water including USP purified water, Labwater and feedwater for high pressure steam.
