Dryden Aqua manufacture 25,000 tonnes of AFM, an Activated Filter Media that replaces sand in sand filters. AFM actually doubles the performance of any sand filter used for drinking water or wastewater treatment. AFM will filter water down to 1 micron, it is a solution to crypto and it will not experience biofouling or transient wormhole channelling of unfiltered water through the filter bed. Currently we have over 100,000 systems operating in Europe and are now rolling out the technology in China and India. AFM is ISO9001-2008, UK Reg 31, NSF50 and NSF61 approved. We have also completed the first stages of ETV.
