Grade 1 glass beads have a small effective size of only 0.6mm to 0.8mm. Its narrow particle size range allows in-depth filtration and extends operating cycles between backwashing. They have been laboratory tested to be able to effectively filter down to below 3 microns and are spherical and do not have any sharp edges. They are safe to handle and safe to service and are manufactured from 100% virgin glass and are chemically inert.
nThe spherical smooth shape results in a low co-efficient of friction reducing its backwash water requirements and backwash with up to 20% less water than sand, saving time and water. Glass beads are easy to install and enable a rapid start-up of the media filter. It high purity means very little backwashing is required to cleanse the filter media prior to commissioning the filter.
