Monitoring Corrosion in Aquifer Thermal Storage Systems - Dr Oliver Opel, University of Applied Sciences Heide Germany

Corrosion and scaling processes in water heating and cooling systems can create the need for hugely
costly repairs. Until now, however, techniques to monitor the extent of the damage they inflict have
been severely limited. In a 2013 study, Dr Oliver Opel and his colleagues at Leuphana University of
Luenburg in Germany made significant strides towards tackling the issue by devising a method to
accurately monitor corrosion and scaling in a large aquifer thermal storage system. Their technique
was based on an easily determinable value named the redox potential.
