A microbiologically fouled industrial cooling water system was investigated utilizing a portable corrosion and fouling monitor according to the NACE RPO189-951  Standard. Baseline data was established and at which time the monitor was subjected to various dispersants (3) typically used for organic and microbiological deposit removal. The results of this in-field, side stream, experiment on a dynamic system will be presented. A number of key points and factors influencing the performance of the foulant clean up will also be discussed.
