AFM - Development and applications of Advanced Filtration Medium
The Advanced Filtration Management (AFM) aimed at developing and testing a product made from a recycled glass, more effective than sand at filtering drinking water. It reduces the need for chemical treatment through improved primary filtration; decreases the use of natural non-renewable resources by replacing virgin sand as a medium; reduce the disposal of glass to landfill; increases sustainability as glass will survive the duration of the filtration system; and decrease industrial wastewater discharge through new applications. Although the product is more expensive than the sand equivalent, it has a longer lifespan and, as a much more effective filter, has health and safety benefits. It has been approved by the Drinking Water Inspectorate, and opportunities for use within the water industry, along with the treatment of sewage effluent, have opened up as a result. Finally, the project established the first full-scale processing facility for AFM from waste glass.
