Water De-ionisation is the process which produces Deionised water. To create deionised water you need to use De-ionisation equipment, this consists of a series of filtering, the filters are made up of resin beds which general water ‘tap water’ passes though the beds neutralizing them which creates the de-ionisation process and produces deionised water.
