swimming-pool filter media

The best known conventional filtering medium used in filtering-circulating equipment. The floating substances are trapped in the gaps between the particles of the filter sand.

A better quality medium than "plain" quartz sand and it is spreading step by step.

• What makes the difference is that throughout the burning process, other particles that can be a perfect ground for microorganism growth are eliminated from between sand particles.
• After installation it can be used immediately.
• The size and wear characteristics of grains is uniform.
• If there is no scaling, it can be used over 8 to 10 years.
• When it is "older" you can still see the difference between burnt and plain quartz sand.

Grain sizes: 0,4–0,8 mm; 0,6–1,2 mm; 1,6–3 mm; 3–6 mm
It has significantly better filtering-and cleaning properties than washed quartz sand. Due to the burning process, the organic pollutants burnt out from the quartz sand, so it will not contain any organic and other materials which facilitate the growth of bacteria or microorganisms. l Available packaging sizes: 25 kg bag
