How Calcium Treatment Units Work

How They Work

As water is passed through the unit, temporary hardness salts – calcium carbonate and magnesium carbonate – and heavy metals are attracted to the CTU’s food grade resin beads and thus removed from the water supply. After softening, water exits the CTU via a silver-impregnated carbon filter incorporated in the central riser tube. This removes any remaining traces of organic matter and chlorine. Unlike some systems, the resin beads and activated carbon are not mixed together.

Canister Exchange
As CTUs cannot be regenerated on site, exhausted canisters need to be exchanged for fresh canisters at predetermined intervals. Frequency of changeover depends on the water hardness and volume of water used. European WaterCare provides a free water testing service to establish the capacity of each unit on site and obtains water meter readings where required to establish the appropriate exchange interval. Exchange can be undertaken by our service department using water hardness and unit capacity tracking of exchange requirements.
