Eutrophication results from excessive nutrient discharge to a water-body, reducing water quality. Eutrophication status must comply with the Urban Waste Water Treatment Directive (UWWTD). As part of a consortium, UHI developed, validated and researched a model (CSTT) capable of screening a water-body for eutrophication. The model was used to defend the UK in the European Court of Justice (2009), against proceedings brought by the European Commission alleging infraction of UK obligations under the UWWTD. The model proved that British waters were not harmfully impacted by eutrophication, sparing the UK government ~£6 billion to implement tertiary sewage treatment across England and Wales.
Aircraft icing is a significant factor in many aircraft accidents and incidents. Ice accretion on the wings has adverse aerodynamic effects, such as loss of lift and control, and ice can also block inlets into key flight sensors. Work by Richard Purvis and his Research Associate, Peter Hicks at UEA, in collaboration with AeroTex UK and QinetiQ, led to better understanding of how the impacts and splashing of water droplets influence the ice that forms on aircraft wings. This led to improved computer prediction codes, which are used by industry to improve design and help satisfy certification requirements.
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.
The consultancy company AeroTex makes use of UCL research findings to design new and improved ice protection systems for fixed wing or rotor aircraft. These new designs enable AeroTex's customers (aircraft manufacturers and Tier 1 equipment suppliers) to comply with upcoming changes that are raising aircraft certification standards and to operate aircraft more safely in icing conditions. The increase in income to AeroTex resulting from this work was approximately [text removed for publication] per year between 2010 and 2013, representing around 15% of AeroTex's annual turnover.
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 at Cranfield has underpinned national policies for managing and allocating the UK's agricultural water resources over the past 20 years. It has supported major reforms in water policy, abstraction legislation and drought management. It has done this by modelling spatial and temporal variations in demand for irrigation, linking this to the financial impacts of water stress on crop yield and quality, projecting future demand, and assessing climate change impacts and potential adaptations. It has also significantly impacted the agri-food sector, helping agribusinesses assess the viability of irrigation and reservoir investment, encouraging collaboration, and reducing risks in the food supply chain.
This case study describes a series of research projects undertaken by Professor Hulya Dagdeviren from 2004 to 2012 on issues related to the commercialisation and privatisation of water and sanitation services, which involved changes in the control and management of former public utilities. In particular, it focuses on the findings and impacts of the studies in relation to the access and affordability of these services for poor households in the developing countries. The results of these studies influenced the policy directions of international institutions, especially the UN agencies, which play an important role in funding projects and policy advocacy that ultimately shape the national policies of the developing countries.
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.
Cranfield's understanding and modelling of aircraft icing, a critical part of the safety, operation and design protocols for all types of aircraft, has changed the way in which aerospace companies approach the design of new aircraft. Cranfield's research has produced high quality predictive software and an extensive experimental validation database the impact of which is its use in the design, optimisation and certification of aircraft and their components.
The impact of Cranfield's icing research is in the design processes for:
This Case Study illustrates how research has had a significant impact on the awareness and management of hydrogen hazards across the UK's pre-eminent nuclear decommissioning and reprocessing organisation, Sellafield Ltd (formerly BNFL). It has enabled Sellafield to:
In addition, LSBU has, since 2008, benefited from contract research from Sellafield valued at over £1 million.
