Man hole Metrics

A new start up founded by a Civil Engineering student has developed a device which would fix to the underside of existing manhole covers, allowing for remote monitoring of the sewage network and collection of data. Providers would then be alerted as to when a routine intervention should take place. This won the Mayor of London 2021 Tech award for technological innovations to help make London a better place to live and work.  

 

New membrane technology to boost water purification and energy storage

Imperial College London scientists have created a new type of membrane technology that could improve both water purification and battery energy storage efforts. 

 

Delivering Clean Water

 

Remove pollutants from water 

Given the UN Sustainable Development Goal 6 of delivering access to water and sanitation for all, how can new materials be deployed to help? Pavani Cherukupally is working on developing low-cost sponges which can remove pollutants from water. This strategy is much cheaper and simpler than using the current standard wastewater technologies as the blog on Designing sponges to deliver clean water explains. 

Cleaning bacteria out of wastewater

Pavani delivered a webinar for Imperial's Institute for Molecular Science and Engineering, describing her work to develop a sponge which can remove bacteria from contaminated water

Oil Contamination

An oil-catching sponge, developed at the University of Toronto and Imperial College London could help thwart water contamination from offshore oil drilling. Further research is being done to investigate how the sponges could also remove bacteria from saltwater.

Pavani was recently selected as a finalist for the 2022 Asian Women of Achievement Awards in the category Science.

Clean Water/Water Recycling

Filtration Membrane

The Li Research Group in the Department of Chemical Engineering designed a new membrane that is more efficient, stronger and more cost-effective at filtering water, with the new membrane 15 times more efficient than current industry equivalents. Their work will help improve the financial feasibility of implementing membrane-based water filtration plants in parts of the globe in dire need of them.  The study ‘High-performance PVDF membranes prepared by the combined crystallisation and diffusion  (CCD) method using a dual-casting technique: a breakthrough for water treatment applications’ by Shah et al., was published in Energy & Environmental Science.

Willow tree roots Sewage filtration 

Natural filtration by willow trees could be the answer to a growing waste problem, producing clean water, renewable biofuels and 'green' chemicals. Researchers have found a way to stem the flow of municipal wastewater by filtering the waste through the roots of willow trees. The integration of wastewater phytofiltration and biomass production within a willow plantation extends this environmental utility with potential economic and social benefits. The study 'Biorefinery potential of sustainable municipal wastewater treatment using fast-growing willow' was published in Science of the Total Environment. 

Antimicrobial Resistence 

Professor Nick Voulvoulis at the Centre for Environmental Policy has won a NERC funded project on Defining the AMR Burden of Antimicrobial Manufacturing Waste as the PI. The collaborative project will assess the role of antibiotics manufacturing in Chennai and Puducherry (India) as a source of antimicrobial resistance in the environment.

 

Energy

Earth-abundant solar pixels found to produce hydrogen for weeks

New findings have shown that devices made of readily available oxide and carbon-based materials can produce clean hydrogen from water over weeks.

The findings from Imperial College London and the University of Cambridge could help overcome one of the key issues in solar fuel production, where current earth-abundant light-absorbing materials are limited through either their performance or stability.

 

Cheaper hydrogen fuel cell could mean better green energy options

Hydrogen fuel cells convert hydrogen to electricity with water vapour as the only by-product, making them an attractive green alternative for portable power, particularly for vehicles.  Traditionally fuel cells rely on a catalyst made of platinum, which is expensive and scarce. Now, a European team led by Imperial College London researcher, including lead researcher Professor Anthony Kucernak innovation has created a catalyst using only iron, carbon, and nitrogen – materials that are cheap and readily available – and shown that it can be used to operate a fuel cell at high power. Their results are published in Nature Catalysis.
