Impressed Current for Cooling Water Treatment
IIC - Independent International Consultants Ltd

Cathodic protection techniques are well understood and are applied throughout industry to effectively protect pipelines and metal structures from corrosion.

This technology has been further developed and modified for cooling water applications where it has the promise of replacing conventional chemical water treatment technologies.

Typically a small cathodic reaction chamber fitted with an anode is installed and electrodes positioned within the cooling circuit to afford cathodic corrosion protection. The water quality is then controlled to both optimise corrosion protection and preferentially precipitate calcium salts within the reaction chamber rather than within the heat exchangers of the cooling circuit.

Microbiological control is achieved by an electrochemical process using electrodes.

IIC Limited has direct experience in the application of this technology and can support clients considering this approach.
