Abstract

A method and apparatus for monitoring deposit formation in a process having an aqueous flow is provided. According to exemplary embodiments, a feed flow of an aqueous liquid is provided onto a receiving surface to be monitored. At least part of a receiving surface is illuminated with at least one light source. Visual data is collected across the receiving surface and analyzed. The quality and type of deposition attached to the receiving surface is classified based on information obtained from the analyzed visual data, and a quantitative scaling and/or fouling indication is computed based on the classification.
