Novel optical fouling monitor for deposit control - A look at its efficacyin a fine paper mill

Uncontrolled microbiological growth can lead to significant slime depositio n. decreased production efficiency, poor product quality, and customer comp laints. In this paper we present a novel Optical Fooling Monitor (OFM) used in a fine paper mill in Canada to optimize a deposit control program. The OEM allowed quantitative comparison of fouling rates on-machine under diffe rent treatment regimes. Fouling measurements showed good correlation with m achine runnability and were useful to predict boilouts and facilitate proac tive adjustments to the program for peak performance.
