Chemistry students develop mechanism that saves 3000 litres of water per week

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.

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.
