Water Tech Spotlight: the latest technology developments in the water industry | September 2021

Technological solutions and innovations are essential to secure a water-wise future. Water Tech Spotlight is a monthly blog which aims to highlight the latest technology developments in the water industry globally. Scroll down to find out more.

1. THE WORLD’S FIRST VALIDATED, MUNICIPAL UV LED DISINFECTION INSTALLATION

The world’s first municipal scale UV LED Installation at Cumwhinton Drinking Water Plant in Cumbria, UK. The use of UVC-LED for water disinfection has been researched for past 10 years and yet the persisting challenge is how to apply a small, low-power, mercury-free LED to a system suitable for a full-scale application. Typhon, a UK‐based manufacturer of UV LED water treatment systems has developed the world’s first validated municipal‐scale UV LED disinfection system which will be installed at Cumwhinton, a United Utilities water treatment plant in the Northwest of England.

2. ASSESSING DEVELOPMENTAL NEUROTOXICITY IN COMPUTER LANGUAGE

To fully understand the long term consequences of toxic substances in the environment, researchers at the Eawag Water Research Institute have developed a computer model that can map the complexity of the nervous system and make predictions about which chemicals might impair the nervous system and in what way. The results are published in Frontiers in Genetics. Read More…

3. HIGH-SELECTIVE PSEUDOCAPACITIVE ELECTRODE FOR WATER SOFTENING

Recent years have seen a growing interest in the use of capacitive deionization as a novel water treatment technology. Researchers at the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences (CAS) recently developed a pseudo-capacitive electrode with high efficiency and selective electrosorption of hardness ions for water softening.

Published in Water Research, an ultrasensitive CRISPR/Cas12a-powered immunosensing method is proposed by engineers from University of New South Wales (UNSW) to quickly and easily identify potentially fatal Cryptosporidium microorganisms. The system produces a distinctive fluorescent glow in the water sample when Cryptosporidium is found. Read More…

5. A GREEN ENERGY INNOVATION FOR WATER SPLITTING

Green hydrogen is a promising clean energy source with great potential to achieve carbon neutrality. At present, electrochemical water splitting is the simplest way to obtain green hydrogen (H2) but yet to be commercialised. Now, a team of researchers from Pusan National University, Korea, have developed a novel electrocatalyst that can enable commercial on-site production of hydrogen from water splitting in an energy and cost-efficient way, and their work is published in Applied Catalysis B: Environmental.

6. NEW FILTERING METHOD PROMISES SAFER DRINKING WATER

Reported in the Proceedings of the National Academy of Sciences, researchers at the Tufts University School of Engineering have developed novel polymer membranes that can mimic the highly selective properties of biological cells and thus separate fluoride from chloride and other ions with twice the selectivity reported by other methods.
