AFM Specifications | Literature & reports | applications summary | AFM is an Activated Filtration media that replaces sand in rapid gravity or pressure sand filters, simply by changing the sand to AFM the performance and stability of the filter will be greatly enhanced. Water quality will improve, chemical consumption, and water consumption will decrease by at least 80%. AFM is more expensive than sand but the return in capital can usually be measured in months.
AFM is an Activated Filter Media, manufactured and activated by Dryden Aqua under ISO procedures to have a high negative zeta potential and catalytic self sterilizing properties. AFM is manufactured from reprocessed glass, but it is not a basic crushed glass filter media.. We have a basic crushed glass filter media product available for low end applications. AFM is a highly processed product which has been tested by independent UK Government laboratories and the water industry and has been certified safe for all water filtration applications. Filter sand has by-passed the regulations because it was in use before the regulations were in place. However man made filtration products are not exempt, and AFM is the only filtration media that is in compliance with the regulations and is safe to use for applications such as drinking water, swimming pools and aquaria.. A basic crushed glass product does not have the surface active properties, there will be a hydraulic lenses effect which leads to channeling, there are also serious health implications for the public and contractors from using a basic crushed glass product. Dryden Aqua have completed a 1.2 million Euro Research Project in co-operation with the European Commission under the Life Environment initiative to solve these problems.

In addition to the product applications and process technology have been developed by Dryden Aqua. AFM is engineered to have surface active properties of adsorption and catalysis as well as acting as a mechanical filtration media. AFM is a great deal more than a recycled glass filter media. AFM-plus AFM-plus is a surface active open structure catalytic molecular sieve will be available in 2007. It has up to 5 times the surface adsorption and catalytic activity as standard AFM. Performance will be almost equivalent to activated carbon, and it will sterilise the water at the same time. The product is not consumed, a simple back-flush recharges the bed.
