Disarming of Hard Water

Hard water, may it come from well or water pipe, can shape up as very expensive – without counteraction calcification cannot be avoided

The harder the water the more scale can be found at the hottest spots in the water system – boiler, flow heater, washing machine, etc. calcify – high energy costs and mending are the consequences

How can formation of boiler and mineral scale be safely prevented?

By eliminating the lime producers (calcium and magnesium salts) from water – and this is done by softening or demineralisation units; if there are no more lime salts in the water, no more limescale is generated.

Only softening or demineralisation units eliminate lime salts from water and hence are always effective.

These units replace calcium salts with sodium salts by means of an ion exchange resin (water softening) or just fix all ions to a resin (demineralisation).

Sodium salts are not able to form a scale deposit due to their very high water solubility, even at high temperatures.

As soon as the ionexchange resin is saturated with calcium salts (= lime / scale) the resin is regenerated with a concentrated saline solution; this saline solution is pumped through the unit and is subsequent released to the sewer. Regeneration is done fully automated!

Corrosivity as a close Companion of Water Treatment

But naturally soft or softened/demineralised water is – the other side of the coin – always corrosive. Hence it is absolutely necessary to adjoin an appropriate corrosion protection agent to the water, at best straight behind the softening/demineralisation unit, by means of a quantity based dosing pump. Thereby it might be absolutely enough to keep the pH value with the correct range.

Only an elimination of lime producers (calcium salts) prohibts safely formation of limescale. Consequently the installation of a softening unit is always successful.
