Let's talk about water

Whetting appetites for Bath's water research

Topic: Water Treatment

Chemistry and Water: Challenges & Solutions in a Changing World

📥  Water Resources, Water Treatment, Water, Environment and Infrastructure Resilience, WIRC @ Bath

We are all aware of the breadth of issues that we face as a planet when it comes to securing sustainable water supplies in the future. Global changes in climate, land use and demographics mean that there will be different pressures on water availability and quality and these have the potential to affect human health and the environment. Whilst some challenges are long-standing, such as ensuring adequate sanitation for all, we also face emerging issues, in the form of new pollutants, such as hormones and pharmaceuticals.

Last year in Leipzig, leading scientists from China, Germany, Japan, the UK and the USA met at the 6th Chemical Sciences in Society Symposium (CS3) to discuss how chemistry could contribute to future global water security. The meeting is part of an ongoing series that brings together leading scientists from these nations, with the support of their national chemical societies and national funding bodies to discuss the role of the chemical sciences in different global challenges.

The discussions from the meeting have been captured in the recently launched white paper Chemistry and Water: Challenges and Solutions in Changing World, which highlights the future research directions, collaborations and policies that are needed to ensure global water needs can be met in the future. The discussion at the meeting encompassed wide range of issues, including  the link between water, the environment and human health, the need for ever-evolving detection methods, improved water treatment techniques and the opportunities presented for recovering valuable materials from water.

A number of themes emerged from discussions across all areas, such as the need for chemists to work alongside other disciplines, such as engineering, ecology and epidemiology and the importance of continual international knowledge exchange and collaboration.  The white paper also makes more detailed recommendations for research directions in the different themes of environment and health, detection, treatment and recovery of materials and includes case studies on how water challenges are being tackled in each nation.

 

Reactor development for water treatment

📥  Water Treatment, WIRC @ Bath

This April sees the next talk in the monthly 'Water Colloquium' series organised by WIRC @ Bath exploring the breadth of water research being undertaken at the University of Bath.

Title: Reactor development for water treatment: From macro to micro scale using bacterial cells, photocatalysis and enzymes

Speaker: Dr Emma Emanuelsson

When: Thursday 28th April 2016 at 1.15pm

Where: Room 4.10, Chancellors' Building, University of Bath (Location and maps)

Abstract: Many industries generate wastewaters that are not suitable for conventional biological wastewater treatment. This could be due to the presence of ‘hard to degrade’ compounds such as pesticides, chlorinated and volatile organic compounds or high concentration of detergents or fats. Other contaminants, such as salts, acids, alkali and metals, may also be toxic to the microorganisms and thus jeopardise the treatment. These wastewaters must therefore be treated before they can be sent to a wastewater treatment plant. The interesting challenge is that there is no ‘standardised approach’, instead a variety of strategies are required to deal with these various contaminants.

Title: The Photochemistry of Rivers, Lakes and Engineered Low-Energy Treatment Systems

Where: Room 3.15, Chancellors' Building, University of Bath (Location and maps)

Abstract: The importance of photochemical processes on the fate of aquatic contaminants is widely underestimated. This lecture summarizes highlights of my own studies and discusses them in relation to recent important advancements in the field of environmental photochemistry, with emphasis on reaction mechanisms, monitoring and modelling of photochemical processes in water bodies. Systematic use of natural sunlight for improving water quality in constructed open water systems such as wetlands and stormwater reservoirs will be considered. The presentation is especially addressed to an audience that is unfamiliar with this area of research as I will provide an introduction to the photophysical and photochemical processes that generate a wide range of short-lived reactive species in the upper layer of sunlit surface waters. Along the way I will also explain what the colour of water is.

Researchers to use algae to clean up mine water

  , , , ,

📥  Water Treatment

We can announce today that our researchers are part of a ground breaking GW4 research project that aims to clean up water from a Cornish tin mine, using algae to harvest the precious heavy metals and produce biofuel at the same time.

mine-waterGW4 is the South West Research Alliance that brings together the South West and Wales’ four leading, research-intensive universities: Bath, Bristol, Cardiff and Exeter.

Researchers from all four universities, in collaboration with Plymouth Marine Laboratory (PML) are now working with the Coal Authority and Veolia to take untreated mine water samples from Wheal Jane tin mine in Cornwall into the laboratory and grow algae in them. The research will explore whether algae is effective in removing materials such as arsenic and cadmium from the mine water.

Researchers will then look to convert the algae into a solid from which it’s expected that precious heavy metals can be extracted and recycled for use in the electronics industry. The remaining solid waste will then be used to make biofuels.

Waste seashells can solve waste water problem

  ,

📥  Water Treatment

Today the University has announced the results of a new research paper by Dr Darrell Patterson that find you can use waste seashells to clean waste water.

Daryl-Patterson-mussel-shells2The thousands of tonnes of waste seashells created by the edible seafood sector could now be put to use by our Department of Chemical Engineering in a new waste water cleaning project.

In the research, waste mussel shells were used to create a cheaper and more environmentally friendly way of ‘polishing’ waste water. This knowledge could now be used to remove unwanted substances like hormones, pharmaceuticals or fertilisers from the water system.
