Uses: The pH correction of potable waters and the remineralisation of soft and desalinated waters
Juraperle is a granular filter material with a calcium carbonate purity of over 99%. Its microcrystalline structure confers superior performance compared with ordinary limestone. Juraperle is a reactive media and during its use it is gradually dissolved by the water being treated and will therefore require periodic replacement. The grain size is 1-2mm. Juraperle complies with BS EN 1018:1998 (Calcium Carbonate).
