FILTER MEDIA - GLASS PEARLS
(20KG/BAG, 0.6MM - 0.8MM)
Whereas other filter media may contain a variety of contaminants, the Glass Pearls are chemically inert for superior purity. In fact, Glass Pearls have been independently lab tested for leaching contaminants and found to be well within Australian Drinking Water Guidelines. Their superior purity greatly reduces its initial backwashing requirements, prior to commissioning a filter, enabling a rapid start up of media filters.
SUPERIOR DEPTH FILTRATION
Conventional media such as sand is crushed and sieved; they generally have an irregular structure and a larger variation in particle size. A conventional media filter bed is more porous and unable to trap fine particles.
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.
The chart below demonstrates that Glass Pearls have a higher bulk density than crushed glass and sand.
Glass Pearl media has an effective size between 0.6mm to 0.8mm. This narrow range in particle size and the smooth spherical shape results in a closer compaction of Pearls as a filter bed whereas sand generally has a larger range of particle size 0.6mm to 1.2mm and irregular in shape results in large porosity or air gapes between particles reducing its ability to provide finer filtration. Please note that the required Glass Pearl filter media weights differ, but the media volume is constant.
The water saving ability of Glass Pearls are due to their spherical smooth shape, as this result in a low coefficient of friction. After each backwash, Glass Pearls are effectively cleansed of their trapped contaminants. Glass Pearls require up to 20% less backwash water than sand, saving time and water.
Glass Pearls required 215 litres to successfully backwash a Waterco S600 Media Filter, whereas sand required 266 litres.
- Superior filtration below 3 microns
- Up to 20% less water required for backwashing
- 0.6mm to 0.8mm in size
- Chemically inert and free from contaminants
The design of glass pearl media is based on the process of depth filtration. As the water is pumped, dirt is trapped in the tiny spaces between the media.
