Chemistry students at Stellenbosch University have managed to reduce their laboratory’s water consumption by at least 3 000 litres per week.
Jonathan Hay, Ph.D. student at Stellenbosch University Faculty of Science explains that, in the past, they had wasted a great deal of water in the lab, but realised this needed to change given the drought situation in the Western Cape.
They have now developed a mechanism which 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.— Jonathan Hay, PhD student at Stellenbosch University
The apparatus and equipment requires 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
