Chemistry students at Stellenbosch University have reduced their water consumption by at least 3 000 litres per week thanks to a mechanism they developed.
Stellenbosch Chemistry students were concerned about their laboratory’s water consumption during the drought in the Western Cape so they developed a mechanism that cools the apparatus and pumps the water back in.
“What we came up with was a simple cooler box system that provides ice cold water to the apparatus, pumping it from the container being a cooler box right back into it.”
“The apparatus and equipment require a lot of water for cooling. Daily it can waste at least 200 litres of water and now the cooler box holds about 25 litres of water including ice.” – Jonathan Hay, PhD student at Stellenbosch University
Jonathan Hay was interviewed by Kieno Kammies on his talk show and the pair discussed how the mechanism has made a big difference in the water consumption of the lab.
Hopefully, this idea can be adapted to other industries that also use high volumes of water.
