1. COMBINING SUNLIGHT AND WASTEWATER NITRATE TO MAKE THE WORLD’S NO. 2 CHEMICAL

A state-of-the-art solar-powered electrochemical reaction technology was recently developed to systematically produce ammonia (NH3), which is ranked as the second most produced chemical in the world. A group of engineers at the University of Illinois, Chicago, developed this cutting-edge technology using wastewater nitrates (NO3) under sunlight. The study is published in Energy & Environmental Science. Read More…

2. AN OFF-GRID SANITATION SYSTEM ENTERS THE MARKET IN SOUTH AFRICA

The NEWgeneratorTM is a multi-purpose off-grid sanitation system developed by experts at the University of South Florida (USF) in collaboration with the Water Research Commission’s SASTEP initiative. This compact, portable and modular future-proof system can improve water reuse efficiency, produce energy from biogas, and provide nutrient-rich fertilizer from its sewage water. This commercial product could be a turning point for safe and sustainable WASH in emerging economies. Read more…

3. USING REMOTE AUGMENTED REALITY TO KEEP ESSENTIAL WATER TREATMENT PLANTS RUNNING

COVID-19 has not only taken a toll on global water and sanitation services but also challenged the adequate surveillance of wastewater treatment plants. However, Veolia North America (VNA) recently trialled a remote augmented reality tool for monitoring and servicing treatment plants, making traditional in-person inspections a thing of the past and minimizing occupational hazards. This successful pilot is an example of streamlining digitalisation and enhanced infrastructure management for water utilities. Read more…

4. FIRST TRIAL OF A NEW LEAKAGE TECH IN THE UK

Anglian Water has successfully trialled a technology to find and measure leaks in live water lines in the UK as part of a new partnership with Electro Scan. This formidable technology employs multi-sensors, low voltage conductivity, acoustic technology, and high-resolution closed-circuit television (CCTV) in detecting holes with a 1cm diameter in water pipes as well as estimating water losses in litres per second.

5. NEW METHOD FOR REMOVING LEAD FROM DRINKING WATER

A group of researchers at MIT have recently discovered a laboratory-based economical and energy-efficient system to remove lead and other notorious heavy metals from drinking water. Published in Environmental Science and Technology – Water, this new approach incorporates a process called shock electrodialysis. With 95% lead reduction results, this method offers huge potential for removing tiny concentrations of persistent pollutants from water. Read more…
