Researchers in Chemical Engineering and Analytical Sciences have worked with our spin-out company Arvia Technology to develop an electrochemical process that has dramatically reduced wastewater pollution levels and enabled water recycling across numerous industries.

The Arvia process has reduced pollutant levels from pesticides to match UK drinking water standards; removed 90% of pharmaceutical residues and natural hormones from industrial wastewater; and reduced the release of high microbial wastewaters which can cause anti-microbial resistance.

Arvia Technology has now installed treatment systems in 25 companies across 11 countries, including the UK and China.

Our National Graphene Institute Membranes Lab has pioneered a graphene-oxide membrane that can filter salts out of water, making it safe to drink.

This game-changing technology is more efficient and affordable than other desalination technologies and could provide affordable and sustainable clean water solutions to millions of people.

Our undergraduate students have assisted a study into the effects of warming ocean waters on the small-spotted catshark embryo’s freeze response: a technique whereby the embryo stops moving so that predators won’t detect them.

The research found that with a 5°C water temperature increase there was a seven-fold decrease in the length of time the embryos froze for in the presence of a predator stimuli, indicating that as oceans warm, many shark and ray species may reduce in number due to increased predation.

With half a billion people worldwide having poor water supplies and two billion with poor sanitation facilities, our two free MOOCs open up access for citizens and leaders around the world to explore what can be done to solve this complex global issue.

At our Jodrell Bank Discovery Centre, we partnered with IncredibleOceans to deliver outreach talks and programmes to raise awareness of how oceans are facing threats from development and overfishing, climate change, pollution, acoustics and more.

We teamed up with scientists, creatives, community organisations, campaigners, companies and broadcast media to maximise the impact of this educational outreach activity.

Life below water, in rivers and at sea, is threatened by waste flowing from urban river channels into the oceans.

We’ve been highlighting the effect of microplastics – very small pieces of plastic debris including microbeads, microfibres and plastic fragments – on river systems and marine life through a range of pro-active media coverage, engagement with water companies and input into UK legislation on water management.

Our work in hydrology and hydrochemistry to understand metals, carbon and gases in water systems has led to the development of a highly successful spin-out company, Salamander, which has brought to market two cutting-edge pieces of water monitoring software – chloroclam and hydroclam – which are being used in industry to improve water and marine system monitoring. We have also undertaken work to understand hypoxia – dead fish zones – which has directly informed marine industry practice on aquatic ecosystems.

Leading the way in achieving the University’s pledge to eliminate avoidable single-use plastic usage, staff in our School of Biological Sciences are reducing single-use plastics in the lab through adoption of a 6R approach.

This has included:

• refining protocol and optimising waste management;
• reducing single-use items;
• re-using materials, plastic containers and gloves;
• using recycled material;
• replacing plastics where possible with glass, paper or wood.
