Abstract
In order to make available water that is as germ-free as possible, the invention provides a water installation system (1) comprising an extraction point (38) and/or an outlet, wherein the water installation system has a direction of flow (D) towards the extraction point and/or towards the outlet, and comprises at least one chemical germ barrier (200) upstream of the extraction point and/or the outlet when viewed in the direction of flow, wherein the chemical germ barrier is selected in particular from the group consisting of at least one alkalinizing and/or oxidative material, silver, chlorine, and combinations thereof.
Claims5
A method for treating drinking water, comprising:
- a stagnation phase in which the drinking water is not being extracted;
- and
- an extraction phase in which the drinking water is extracted,
- wherein the extraction phase includes
- receiving water from a water source,
- passing the water through a chemical germ barrier, and
- delivering the water to an outlet, and
- wherein the stagnation phase includes
- exposing the water while stagnant within the chemical germ barrier to a material having an alkalinizing effect, and
- enriching the water in the chemical germ barrier with OH-ions such that during the stagnation phase the drinking water assumes a pH in the range of 9 up to 13.
