Disinfecting drinking water with silver is a very old method and has been adopted frequently in many parts of the world. As a matter of fact, this method goes back to antiquity.

Disinfection of water by dosing silver ions into water is completely harmless to human as well as animals. The amount of silver ions in the disinfected water is well below the maximum amount stated e.g. in the directives issued by the WHO.

Silver ions do not change the taste, smell or colour of the water. Nor do they effect the physical and chemical properties of the water. The silver ions only kill off bacteria, germs, algae etc..

Efficient and Durable! “Made for Marine” pressure vessels

The dosing/chlorinating unit is meant to dose a chemical into water. The chemicals can be chlorine for fresh water systems.
