- Improved capacitive deionization by using novel carbon materials
Speaker: Professor Dengsong Zhang from Shanghai University
When: 29th May 2019, 13:15-14:05
Where: 1 West North Building, room 3.11, University of Bath, Claverton Down, Bath BA2 7AY
Water crisis has become one of most great threatening issues resulting from the fresh water. Various emerging desalination technologies were developed to resolve this crisis. Capacitive deionization is a promising water treatment technology that can replace the traditional commercialized method in the future.
It is quite challenging to find highly efficient electrode materials with high salt adsorption capacity. Novell carbon such as graphene and their composites have been developed and used as highly-efficient electrodes for capacitive deionization by us. These materials could be applied to for desalination, reclaimed water reuse, and removal heavy metal ions from wastewater. Our work offers a promising solution to develop high-performance electrode materials for removal of ions from wastewater and saline water.
Speaker profile: Professor Dengsong Zhang received his B.E. and Ph.D. degree from Shanghai University in 2002 and 2007, respectively. He then joined Shanghai University as a Lecturer. He also worked as a Research Fellow at the SHU-ESSILOR (France) Joint R&D Center.
He was elected as Shanghai Education Commission’s Dawn Scholars in 2008 and Shanghai Science and Technology Commission’s Youth Venus in 2010. He was appointed as a Professor of Chemistry at Shanghai University in 2013. His scientific interest is focused on environmental science and technology. He has published more than 130 publications.

- The Wessex Water Cycle: Challenges and Research
Speaker: Ruth Barden from Wessex Water
When: 14th March 2019, 13:15-14:05
Where: 6 East Building, room 2.2, University of Bath, Claverton Down, Bath BA2 7AY
Covering the key elements of the water cycle from a water company perspective from source to tap to toilet to sea. The talk will highlight the current and future challenges, our approach to addressing these, including the academic research which has helped to inform our strategies. The integration and impact of relevant research on our decision making will be highlighted.
Ruth Barden is the director of environmental strategy at Wessex Water leading on catchment based approaches, environmental planning, biodiversity and delivery of the Water Framework Directive, including the Chemical Investigations Programmes. She has worked at Wessex Water for more than 10 years, always in an environmental capacity but ranging from undertaking environmental impact assessments to liaison on permitting. A key part of her role is delivering an ambitious environmental investigation programme and identifying novel technologies and approaches to achieve environmental improvements at an acceptable cost to customers.

- A global perspective on the local challenges of water, waste and climate change in Bath
Speaker: Kees van Leeuwen, Global Chair and David Parking Visiting Professor at Water Innovation and Research Centre (WIRC@Bath)
When: 5th February 2019, 17:15-18:05
Where: Chancellor’s Building, room 2.6, University of Bath, Claverton Down, Bath BA2 7AY
Globally, more than half of the world’s population resides in urban areas, and this figure is projected to increase to 66% by 2050. Cities are important engines of innovation and wealth creation, as well as a sources for improved efficiencies for the use of materials and energy. On the other hand, primarily due to the concentration of people in a relatively small area, cities also act as centers of intense resource consumption and pollution. Rapid urbanization along with effects of climate change, creates multiple challenges regarding water quality, water scarcity, and flooding resulting in high vulnerability and, sometimes, unforeseen consequences.
Our research has been carried out in the context of EIP Water. Globally more than 70 cities have been assessed, including Bath. The presentation will focus on the general challenges in cities, water management and governance, the importance of developing co-benefits with other sectorial challenges in cities. Results of Bath will be presented too. Challenges can be met by developing and implementing further initiatives: (a) by creating awareness among potential partners (cities and regions), (b) by networking, and (c) by sharing best practices among cities to allow municipalities and regions to provide solutions to their urban water challenges.
The talk will be followed by a reception in the 2nd floor foyer of the Chancellor’s Building, 18:05-19:30.
Kees van Leeuwen is Principal Scientist at KWR Watercycle Research Institute and holds a Chair at the Copernicus Institute (University of Utrecht, the Netherlands) on water management and urban development. He currently coordinates the City Blueprint Action Group of EIP Water. He is a University of Bath Global Chair and his appointment has been funded by the International Relations Office’s Global Chair scheme, a flagship programme designed to attract distinguished, globally renowned scholars to engage in high-profile research activities at Bath.

- The Drought and Water Scarcity Programme (UK research)
Speaker: Jamie Hannaford, CEH Wallingford
When: 3rd December 2018, 17:30-19:00
Where: Faculty Lecture Theatre, Trevithick Building, Cardiff University, CF24 3AA
The UK Droughts & Water Scarcity research programme is a five-year interdisciplinary, £12 million+ NERC programme in collaboration with ESRC, EPSRC, BBSRC and AHRC. It is supporting improved decision-making in relation to droughts and water scarcity by providing research that identifies, predicts and responds to the interrelationships between their multiple drivers and impacts.
The programme’s research is UK-focused, and contributes to NERC’s natural hazards and climate system strategic science themes.
Four projects are funded under the UK Droughts & Water Scarcity programme:
- Historic Droughts : Understanding past drought episodes to develop improved tools for the future
- IMPETUS : Improving predictions of drought to inform user decisions
- MaRIUS : Managing the risks, impacts and uncertainties of drought and water scarcity
- DRY : Drought risk and you
The UK Droughts & Water Scarcity programme has recently (April 2017) funded the final phase of the Programme that will build on the co-ordinated work of the four research projects to maximise the impact of the Programme for a diverse range of stakeholders in droughts and water scarcity. AboutDrought will provide access to all the outputs of the UK Droughts & Water Scarcity programme.
No booking required. More information on http://aboutdrought.info/
- ‘Taking waste out of wastewater’ by Mark van Loosdrecht
Professor van Loosdrecht, together with Professor Bruce Rittmann, was named the 2018 Stockholm Water Prize Laureate for his pioneering role in the water-related environmental biotechnology revolution currently taking place. Rittmann and van Loosdrecht have both played a leading role by presenting new knowledge around microbiological processes in wastewater, but their contributions are not only academic. Their research has also led to a new generation of water treatment processes that make it possible to remove harmful contaminants from water, cut wastewater treatment costs, reduce energy consumption and even recover chemicals and nutrients for recycling. The Environmental Biotechnology research group around Professor Mark van Loosdrecht at Delft University of Technology in The Netherlands has contributed a number of patented innovations that have turned wastewater treatment on its head.
