📥  Urban water management, Waste water collection and treatment, WIRC @ Bath

On 13 February 2018, Jannis Wenk, Davide Mattia, John Chew and Jan Hofman visited the Urban Water Systems Engineering group of the TU Munich. Our hosts, Prof Jörg Drewes and Dr Uwe Hübner presented the work of chair and showed their impressive pilot plants and research facilities. The group of Prof Drewes is working on a wide range of topics in the field of water and wastewater engineering. One of their focal points is the research on the removal of organic micropollutants in Managed Aquifer Recharge systems. Their research in this field included small scale filter column tests, a large sand-filled pilot plant and full-scale experiment in Berlin near the Tegelsee. Another interesting project was the power-to-gas project in which carbon dioxide and hydrogen were converted to methane gas in trickling bed filters. The gas has a high purity and can be fed directly into the gas grid. The hydrogen was obtained by water electrolysis with electricity from renewable sources in times of low demand.

Besides these two topics, further research was amongst others on ozone systems, UV oxidation, Anaerobic Digestion, Analytical screening techniques, environmental behaviour of microplastics, the urban water-energy-food nexus.

The WIRC delegation gave an overview of WIRC and our research on new materials for water treatment, microbubbles, fluid dynamics gauging and heat recovery from sewers. In the discussions it became clear that there are very good opportunities for collaboration. Jannis Wenk is already involved the supervision of Sema Karakurt, one of the PhD students in Munich. We anticipate that the visit will be followed up by some more visits and possibly PhD student exchanges. Dr Uwe Hübner will visit Bath in the future for a combined Chemical Engineering Seminar and Water Colloquium. The exact date will be announced.

📥  Water, Environment and Infrastructure Resilience

The following post was contributed by Dr. Chrysoula Papacharalampou, a Research Associate in the Department of Architecture and Civil Engineering.


Research currently undertaken within the Research Unit for Water, Environment and Infrastructure Resilience (WEIR) sheds light on the utility of re-constructed flood flow data derived from historical evidence for enhancing contemporary flood risk assessment.

The focus of the interdisciplinary research project (funded by the Leverhulme Trust and involving historical architecture, hydraulic engineering and statistical modelling experts from Universities of Bath and Edinburgh) is the River Avon and its interactions with the historic City of Bath, over the last three centuries. The research aims to translate documentary evidence (e.g. historical newspaper articles, epigraphic evidence, and pictorial representations) into hydraulic models which represent past extreme conditions of the river. It also analyses the historic symbiotic links between the flooding events of the Avon River with the economic and cultural development of the City of Bath. The underpinning methodology contributes a structured approach for reconstructing historic flood events and integrating them into contemporary flood risk and policy analyses.

Collaboration visit from University of Johannesburg to Bath

📥  Sensors and data

The following post was submitted by Professor Frank Marken from the Department of Chemistry.


A postgraduate researcher, Luthando Tshwenya from the University of Johannesburg, visited Bath with support from the DST/Mintek Nanotechnology Innovation Centre, University of Johannesburg, Water Research commission and the National Research Foundation, South Africa to pursue research into water desalination treatment with “ionic diodes”. The project is based on a collaboration of Professor Omotayo Arotiba in Johannesburg and Professor Frank Marken at Bath. During the three month stay, Luthando was able to develop new types of diodes by hot-pressing together polymer films. The micro-devices were shown to rectify cation flow and they could in future be combined with an anion rectifier to give a novel water desalination system that is driven by AC electricity without any side reaction or requirements for pumps. Water research features prominently at Bath and at the University of Johannesburg where Luthando plans to further develop this technology in his PhD.

Luthando presented his work at the Electrochem 2017 conference in Birmingham and a joint publication has been submitted entitled “Cationic Diodes by Hot-Pressing of Fumasep FKS-30 Ionomer Film onto a Microhole in Polyethylene Terephthalate”. Coauthors in this work are based in 4 institutions including:

  • Department of Applied Chemistry, University of Johannesburg, South Africa
  • Department of Chemistry, University of Bath, Bath BA2 7AY, UK
  • Centre for Nanomaterials Science Research, University of Johannesburg, South Africa
  • Department of Chemistry, Faculty of Mathematics and Natural Sciences, Bogor Agricultural University, Bogor, West Java, Indonesia
  • University of Groningen, Groningen Research Institute of Pharmacy, Pharmaceutical Analysis, 9700 AD Groningen, The Netherlands

The project will rely on the collaboration with governmental and industry partners.

Dr. Danielle Wain from the Department of Architecture and Civil Engineering has been awarded a Industrial Mobility Fellowship with a project titled "Stirring things up: Do surface mixers in drinking water reservoirs improve water quality?". The project will focus on turbidity in raw water and will be a combined field and modelling project on Durleigh Reservoir with Wessex Water.

 

Test to prevent crippling fluorosis

  , , , , , ,

📥  Water supply from source to tap

A research team at the University of Bath’s Centre for Sustainable Chemical Technologies, and the Water Innovation and Research Centre (WIRC), led by Simon Lewis, has developed a simple colour-changing test that detects high levels of fluoride quickly and selectively. The test changes from purple to blue when the levels of fluoride in the water are too high. Whilst the test is at the proof of concept stage, the team aims to develop it into a disposable test strip that is low cost and easy to use by anyone.

The Bath researchers are partnering with the Nasio Trust, a charity that works to protect and support vulnerable children in East Africa, to develop their system for ease of use in the field.

The team is now looking for additional partners to take the technology forward and help develop the test. They are also working towards adapting the technology to other types of notorious water contaminants of global concern, including mercury, lead and cadmium.

The core project team consists of Carlos López-Alled, Simon Lewis, Jannis Wenk and Tony James.
