BIOCIDAL EFFICIENCY OF CORROSION INHIBITORS

Felicia Rajammal Selvarani, C. Merlin Rose

Cooling water systems are extremely vulnerable to microbial contamination. Problems occur when microbes begin to proliferate and attach to system surfaces.Corrosion can also result from unchecked microbial growth. Microorganisms such as bacteria, fungi and algae can combine with organic compounds to form biofilms. The microbes in these films produce products of metabolism that are corrosive in nature. The result is pitting and corrosion of metal components.To eliminate the threat of such potential problems and achieve optimum system efficiency, microbiological activity within a system must be properly controlled. Surfactants are normally added to control microbial activity. This paper is concerned with the comparative study of biocidal efficiencies of CTAB, CPC and SDS in the presence of the inhibitor oxalic acid in carbon steel.
