The present invention relates to a method of measuring hydrophobic contaminants in a pulp slurry or papermaking system, comprising the steps of: providing a paper mill aqueous sample, filtering the paper mill aqueous sample to produce a filtrate comprising particles, and collecting the measured volume An image of the particles in the filtrate. The method also includes the steps of: analyzing the image to determine the size and morphology of the particles in the measured volume of the filtrate, identifying spherical particles having a size ranging from about 1 micron to about 20 microns in the measured volume of the filtrate, and The number of such spherical particles having a size of from about 1 micron to about 20 microns in the filtrate of the measured volume is quantified. This method can be used by papermakers to optimize deposition diagnostics, prevention, and contaminant control processing. |
