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.
