PPG Glass

Produced by Dryden Aqua in their own factory and in strict compliance with their ISO certified process, PGFM is one of the highest quality refined glass filter medias on the market. Glass is first washed, decontaminated and then carefully broken to the appropriate particle shape and size. Great care is taken to ensure dangerous glass splinters do not get into the finished material and the organic load is below 400g per ton. PGFM is different to AFM® as it does not undergo their patented activation process and is manufactured from mixed glass including white glass. Although PGFM is not bioresistant, it biofouls less and is therefore a better filter media than sand making it the perfect solution for the generic sand market and for the price sensitive customer less concerned with exceptional performance.

AFM NG

As a result of 35 years of Reseach & Development, AFM® (Activated Filter Media) is a direct replacement for sand that can be installed in all types of sand filters without modifications. Manufactured from green and brown glass, AFM® is exposed to a unique activation process to become self-sterilizing and acquire superior mechanical & electro-static filtration performance.

Removes 30% more material and pollutants than sand, saving on backwashing and the resultant water, energy and chemical treatment costs. Keeps cleaner as it is less susceptible to bio-fouling. As the product is heat treated surfaces are smooth, requiring less remedial action and less chemical treatment to kill pollutants. Less dense than sand, requiring 20% less media to fill the filter. Particle shape provides a 30% improvement, reducing turbidity. It doesn’t degrade, therefore having a longer life span. Suitable for both commercial and domestic applications. Grade 1 is equivalent to 16/30 grade sand. Grade 3 is equivalent to 6 mm gravel.
