Monitoring Biocorrosion and Biofilms in Industrial Waters: A Practical Approach

Source

This paper describes a practical approach to the assessment of biotic and abiotic processes at the metal/solution interface, introducing a nonconventional multipurpose sampling device that can be used in a conventional side-stream corrosion rack. The complete monitoring program for biofilms and corrosion in water-using systems includes parallel field and laboratory measurements, in addition to the sampler exposures. This device can simplify collection of samples for biofilm and corrosion product analyses, facilitate field and laboratory studies for biocide selection, and provide a useful source of samples for assessing corrosion and biofouling effects in the system. Two practical cases, involving an industrial cooling water system and a secondary oil recovery water injection line, are briefly described to illustrate the effectiveness of the monitoring program.
