KIESELGUHR CERAMIC – STAGE ONE
Doulton ceramic is made from Kieselguhr Diatomaceous Earth and fired to above 1000 degrees Celsius. Over 80,000 overlapping pores make up each element. This feature provides absolute mechanical filtration with a 99.999% rejection of bacteria and cysts. Bacteria and any other foreign particles as small as 0.2 of a micron are trapped on the outside of the element while the water passes through the ceramic wall to the inside of the element.
