Drinking Water Purification


SGS-polymers are applied in reusable filters for the drinking water purification in the household. In a combined adsorption and filtration process suspended materials as well as iron, lead, chromium, zinc, copper, aluminium and other metals are removed from the drinking water by SGS-polymers. Furthermore, organic compounds and bacteria are eliminated. The following table gives a survey of the purification efficiency.

Water impurifying substances Purification efficiency
Solids > 5 µm 100%
Suspended materials (rust, clay/loam, algae) 100%
Heavy metals and radionuclides (iron, lead, cadmium, copper, Cs-137, Sr-90) 99.7%
Chlorine 95%
Organic compounds (pesticides) 99%
Microbes, coli-bacteria 99%

Throughputs up to 400 l/h (660 bed volumes per hour) are realisable. Even at home the regeneration of the charged SGS-polymers is very simple. A solution of common salt (sodium chloride) can be used for this purpose.
