Researchers funded for German water treatment

Glasgow Caledonian University (GCU) researchers are working to produce cleaner drinking water for the four million people who are supplied from Lake Constance, a lake on the Rhine at the northern foot of the Alps.

GCU’s Professor JiaQian Jiang has been funded by German water treatment company Lake Constance Water Supply for a three-year project to develop advanced oxidation processes for treating drinking water which leave fewer pollutants.

His research investigates the treatment of water and waste water with processes using ferrate, a supercharged iron ion, and Fenton's reagent, a technique that is used to oxidize contaminants in water and waste waters.

It is thought that advanced oxidation processes produce fewer potentially toxic by-products than the current water treatment processes to degrade harmful micro-pollutants and to kill germs.

Professor Jiang said: “Our earlier three-year project tested ferrate in the water treatment process together with a toxicity assessment trial. Initial laboratory and pilot-scale studies have shown that the ferrate technology produces an excellent performance. Following that, Lake Constance Water Supply has decided to offer additional three-year funding to comparatively evaluate various advanced oxidation processes to treat the water to the highest water qualities.”
