The zebra mussel is one of the world's most damaging invasive species, but existing control approaches cause significant environmental damage. Researchers at the University of Cambridge have developed the patented `BioBullet', which encapsulates a toxic active ingredient in a harmless edible coating, enabling efficient, targeted product delivery and dramatically reducing environmental pollution.

New characterisation tools for natural organic matter (NOM) in drinking water are now used as standard practice within water companies such as Severn Trent Water, United Utilities and Yorkshire Water. The tools inform decisions, and help develop strategic plans on catchment management, source selection, treatment optimisation, and disinfection practice. Water companies experienced difficulties in treating high levels of NOM. Cranfield created a novel characterisation toolkit to measure NOM for its electrical charge and hydrophobicity. Also, new techniques for measuring aggregate properties and emerging disinfection by-products have provided a comprehensive analysis. Two novel treatment technologies are currently marketed. These technologies have raised international interest, resulting in industrial development in Australia.
UK Species Action Plans (SAP) and selection of Special Areas of Conservation under the EC Habitats Directive for declining populations of the critically endangered freshwater pearl mussel Margaritifera margaritifera were informed by QUB research. As an element of the Northern Ireland SAP, in 2009 about 350 mussels produced in a unique captive-breeding facility at a fish farm were released into a river where mussels face extinction. Up to 99% of released mussels survived and a further 240 additional juveniles were released in 2013. This approach complements policy for habitat restoration through catchment management, was a first in Europe and is now being emulated for endangered populations in Austria.
Diarrhoeal disease is the world's second most common cause of death in children under five years old, killing 760,000 children each year according to the World Health Organisation (WHO). Microbial contamination of drinking water is one of the most important causes. In England and Wales acute diarrhoeal disease is estimated to cost the country £1.5 billion annually. UEA epidemiologists have shown the important role of water supply systems in spreading diarrhoeal disease in developed and developing countries; led WHO research projects on small scale drinking water systems; and influenced WHO policy on small scale drinking water systems in developed and developing countries. Methodological research on epidemiological methods for monitoring and regulating bathing water quality has led to changes in WHO guidance on bathing water quality standards and influenced US Environmental Protection Agency criteria. Hunter's participation in international expert panels facilitated the impact of this research on policy.
By modelling the formation of micro-bubbles and the flows induced by them, researchers at the University of Cambridge Department of Applied Mathematics and Theoretical Physics developed a new, low-cost nozzle design that could be retrofitted to existing Dissolved Air Flotation (DAF) systems. This new design dramatically improved the performance of DAF systems, used by the water industry for the production of drinking water. Specifically, this research has enabled a substantial increase in throughput and effectiveness of the flotation process, whilst simultaneously providing a dramatic decrease in the energy requirement.
This study analysed the shallow well drinking water quality of 17,000 rural Malawians. Water officials were advised interim precautions to take regarding grossly contaminated wells. Inter alia, the `Water Resources Investment Strategy', World Bank funded, captured this data to help develop policy. A new MSc course was established to educate water officials. Workshops/Fieldtrips integrated this research into the undergraduate curriculum. An indigenous sustainable natural water purification system was developed to reduce contaminates at source. Initial data indicates that water quality can be improved by up to 80%. This has the potential to improve the water quality for 1.5 million Malawians.
University of Surrey has a strong legacy of research into membrane separation and osmosis, culminating the commercialisation of Surrey's spin-out company Modern Water plc. Modern Water plc. was floated on AIM (London Stock Exchange) in June 2007 raising £30m cash with a market value of £70m.
The research itself is having direct impact via the operating desalination plants in Gibraltar and Oman producing high quality drinking water typically using 30% less energy than conventional desalination plants. In Oman, because of the poor quality of the feed water the forward osmosis process uses 42% less energy per litre of water produced when compared to convential equipment. The two plants currently operating in Oman serve 600 people in Al-Khuluf and 800 people in Naghdah.
Spinout Salamander was created to exploit research in the UoA on environmental monitoring. Building on the research, the company has developed and marketed a suite of branded products: two for monitoring water-quality in distribution (Hydraclam® and Chloroclam®) and one for monitoring ground gas (Gasclam®). In each case the defining feature is the ability to provide secure, standalone, continuous monitoring. The products have been licensed to Siemens (Hydraclam® and Chloroclam®) and Ionscience (Gasclam®), and have had significant impact on "best practicable means" and, hence, major impacts on regulated industries. Since 2008, Salamander has received royalties of over £1.0m, commensurate with end-user sales of £7.0m.
The impact of research by the University of Southampton into global access to safe drinking water has: (i) provided important evidence for new policy initiatives by the World Health Organisation and UNICEF to promote home water treatment to reduce the 1.9 million deaths each year due to water- related infections, and (ii) stimulated debate among a range of stakeholders, including the media, advocacy groups and UN bodies, by challenging the accuracy of the assertion by the UN Secretary General that the UN Millennium Development Goal for safe water access has been met.
Research has led to improvements in the performance over 16 million water meters manufactured by Elster Metering Ltd. since 2008, extending their working lifetimes and reducing maintenance costs. In particular, research on polymeric replacements for the glass in water meters helped Elster establish their product development strategy, and led to changes in the manufactured meter. Brunel University research identifying a specific set of acetal polymers that reduce the degradation of the bodies in water meters has been incorporated in 1.8 million water meters. These meters have less embodied carbon dioxide, and are less prone to theft than the meter with brass components they replace. This innovation allowed Elster to reduce the costs of manufacturing in the UK, thereby maintaining a strong competitive position within the market for water meters.
