An innovative water treatment product developed by an Edinburgh company could have a transformational impact on public health, marine biodiversity and climate change.

Dryden Aqua was named the winner of The European Marine Energy Centre (EMEC) Environmental Technology Verification (ETV) competition launched by Scotland’s energy minister earlier this year.

An R&D intensive marine biological company specialising in sustainable water treatment technologies, Dryden Aqua will now be taken through the full ETV process to verify the environmental benefits of its innovative water treatment product, AFM (Activated Filter Media), which is a direct replacement for sand in sand filters.

Dave Wakefield, EMEC’s ETV manager said: “Dryden Aqua submitted a solid proposal, stating a number of environmental benefits associated with AFM. EMEC will now progress the product through the ETV process to independently verify the environmental claims.

“On completion of the ETV process, EMEC will provide Dryden Aqua with a Statement of Verification proving that the claims about their technology are credible and scientifically sound.”

The majority of drinking water worldwide is treated by sand filters but all suffer from transient wormhole channelling, allowing unfiltered water to pass into drinking water. Up to 80% of all diseases in the developing world are caused by drinking water, mostly by parasites passing through these channels.

AFM offers a potential solution as it has been engineered to adsorb small particles and chemicals from water to provide a safe, high quality water.

It is an innovation capable of revolutionising the way water is filtered, removing pathogens and toxic chemicals such as arsenic and chromium from the water supply.

AFM is being made by recycling glass bottles so Dryden Aqua could contribute hugely to the health of Scotland with less glass going to landfill, and also by reducing the need for sand mining which protects river, sandy beaches and destruction of the seabed ecosystems by dredging.

Howard Dryden, managing director at Dryden Aqua said: “AFM has the potential to be a disruptive technology. Our filter media will more than double the performance of any drinking water system simply by replacing the sand in the filter.  AFM also has the benefit that it is a lower cost and a more sustainable process than any other form of water treatment. Once AFM is in a filter, it should never need to be changed.

“Verification of AFM via EMEC’s ETV programme will allow us to enter the drinking water market more effectively, and much quicker, so we can bring clean and safer water to more people. In the developing world this means we could eliminate up to 80% of all disease and save lives.”

The ETV scheme is open to SME developers of energy, water treatment, or materials and waste technologies who can show that their technology is innovative and has environmental added-value, and whose performance characteristics are not fully covered by existing regulations and standards.
