Filtration first for Affinity Water

Posted: Thursday 28th March 2013

As part of a major refurbishment project, Affinity Water is installing filtration media derived from recycled glass at its Egham water treatment works. This represents a UK first for the application of a glass-based filtration product (DMS Enviro’s Glasmedia) at a public water supply, and is in line with Affinity Water’s on-going commitment to use sustainable materials in its business.

The application of a glass filtration product at Egham represents the culmination of several years of development work on alternative filtration materials with other partners. The starting point was a major collaborative Portfolio project led by innovative research consultancy WRc plc which evaluated a number of alternatives to conventional filtration media. This identified crushed glass as a potentially cost-effective and sustainable alternative to sand. Subsequently, DMS Enviro undertook additional work, supported by WRc and WRc-NSF, to develop Glasmedia and to achieve DWI approval for its use with potable water in 2012. More recently Affinity Water undertook on-site trials to compare sand with alternative filtration materials - this identified Glasmedia as the best option for Egham on the basis of water quality and cost.

Richard Lake, Process Engineering Science Manager Affinity Water, comments: “this application of recycled glass to filtration represents a milestone for Affinity Water, in terms of finding cost-effective, and yet sustainable, alternatives to conventional materials. It has wider implications for the UK water industry.” Mark Watts, Project Manager, WRc comments: “we are delighted to see this example of the long term benefits of our collaborative R&D work with the industry”.
