IMPLICATIONS OF VARIOUS DISPERSANTS ON BIOFILM CLEAN UP PROCESSES

A microbiologically fouled industrial cooling water system was investigated utilizing a portable corrosion and fouling monitor according to the NACE RPO 189-95 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.
