SiLiBeads® Water

Glass beads of soda-lime glass with polished surface as filter material
Conventional filter material, such as quartz sand or granules, is extremely susceptible to attack by fungi, bacteria, germs, algae and calcification due to its porous, irregular structure.
Contaminations and germs settle in the unevenness of the coarse-pore surfaces of the filter material, multiply uncontrollably and indefinitely in the warm pool water. They are never completely removed even during the backwashing process. This requires an unnecessarily high use of expensive and sometimes environmentally harmful chemical disinfectants.
