Glass Pearls for Filters
Glass Pearls Filter Media
Manufactured from 100% virgin glass, Waterco glass pearls are a new generation of filter media, capable of providing water of superior clarity and requiring less water for backwashing.
Glass Pearls are man-made to specific geometrical shapes providing an extremely narrow particle size range of 0.6mm to 0.8mm, enabling the creation of a dense homogeneous filter media bed, capable of filtering particles down to 3 microns. A micron is equivalent to one millionth of a metre
Special features of Waterco’s Glass Pearls media for swimming pools:
Superior clarity – a narrow 0.6mm-0.8mm particle size range provides in-depth filtration and extends operating cycles between backwashing
Exceptional purity – manufactured from chemically inert 100 per cent virgin glass, the pearls have been independently laboratory tested for leeching contaminants
Safe and smooth – free from sharp edges, the pearls’ spherical shape is safe to handle and service and, if the filter’s laterals ever fail and the media flows into the pool, the beads pose no risk of injury to swimmers
Saves water – the smooth shape reduces friction, which then reduces backwash requirements . Glass Pearls required 215 litres to successfully backwash a Waterco S600 Media Filter, whereas sand required 266 litres.
Time saving – easy installation enables a rapid start-up of the media filter. High purity requires very little backwashing to cleanse the Glass Pearls Media prior to commissioning the filter
Long life span – a specialised heat treatment process reduces degradation and increases life span
