In the world of water treatment, corrosion is a major concern. If not controlled, corrosion can lead to poor energy transfer in heat exchangers, creation of favourable microbiological conditions in cooling towers, and even complete failures in steam boilers. Pipework, heat transfer surfaces and externals are all susceptible to corrosion.
The rain water that all too often falls from our skies is naturally soft. But once it falls to the ground and percolates through rocks, it gathers naturally hard mineral salts. It's these calcium and magnesium salts that are responsible for the majority of the scaling in the UK water system.
