Description
PGFM is one of the highest quality refined glass filter medias on the market. It is produced by Dryden Aqua in own factory in strict compliance with our ISO certified process. The glass is first washed and decontaminated and then carefully broken to the appropriate particle shape and size. Above all they make sure no dangerous glass splinters can get into the filter material and that the organic load is below 400g per ton. But PGFM is not AFM®. PGFM does not undergo our patented activation process and it is manufactured from mixed glass – the white glass is not sorted out.
Nevertheless, PGFM is a better filter media than sand because it biofouls less, but it is not bioresistant like AFM®. PGFM is the answer to compete in the generic glass sand market and a highly price sensitive customer segment less concerned about exceptional performance.
Glass sand by Dryden Aqua: Priced to compete with other glasss sand on the market, but with a higher quality.
