GLASS PEARLS

Glass media is an alternative to sand used in media filters. It has many advantages over sand but not all glass medias are created equal. The gains in filtration performance lie in the processing of the media. The uniformity coefficient of Glass Pearls is far greater than that of sand limiting the void space of the filter bed. When the void space of a filter is low, the likelihood of particles getting through the bed are greatly diminished. Glass Pearls have a narrow particle size range of 0.6 mm to 0.8 mm. The bulk density of different media can be a great indicator of filtration performance. Bulk density is measured in unit weight per unit volume. Glass Pearls have a bulk density of 1.61 g/cm³, where traditional silica sand have a bulk density of 1.47 g/cm³. Glass Pearls have been laboratory tested an verified to be chemically inert with no contaminants and media beds require 20% less back washing than traditional sand filters. If your looking for a high performance filtration media Glass Pearls will meet your expectations.
