The glass sand<\/strong> is a filter medium made from recycled glass, designed to replace conventional sand in swimming pool sand filters. Its filtration fineness reaches 1 to 15 microns<\/strong>, compared with 40 to 55 microns for traditional sand. Non-porous and self-sterilising, it prevents the formation of biofilm and reduces the use of disinfectants. Its lifespan exceeds 8 to 10 years, which is twice that of sand. Choosing the right product and the correct particle size makes all the difference.<\/p>\n\n\n\n

What is filter glass for swimming pools?<\/h2>\n\n\n\n

Composition and manufacture of filter glass<\/h3>\n\n\n\n

Filter glass is made from crushed, washed and polished recycled glass<\/strong>. Unlike the silica sand<\/a>, its smooth, non-porous surface prevents organic residues from sticking to it.<\/p>\n\n\n\n

The manufacturing process involves several specific stages:<\/p>\n\n\n\n
