Ion exchange, demineralizers
When the required water quality (conductivity or TDS) cannot be guaranteed with reverse osmosis equipment or may be lost through storage, this is achieved through ion exchange demineralization technology.
Ion exchange technology operates using a mixed bed resin, which combines cationic resin that exchanges cations for hydrogen (H+) and anionic resin, which exchanges anions for hydroxyl (OH-), which when combined with hydrogen forms H2O .
It is recommended to use them after a reverse osmosis system because, thanks to the low conductivity of osmotic water, the resin has a long useful life, so in most cases it is not profitable to provide a system for its regeneration. For low flow applications, disposable cartridges are available and for higher flows we offer fiberglass tanks with disposable resin.
The latter are composed of a fiberglass and polyethylene tank, with a Noryl head, a filling/draining plug, a micro-slotted internal collector for PVC and a filter bed composed of mixed bed resin.
In applications where very high water quality is required (less than 1 µS/cm) two demineralizers are provided in series. This helps to provide the best water quality and at the same time allows us to deplete the resin as much as possible before disposing of it.
Each demineralizing unit is equipped with a conductivity sensor at the outlet and a board housing the display where the measured value can be observed.
