Abstract: A method of increasing chemical efficiency of chemical additives in a papermaking system includes the steps of providing thick stock pulp comprising soluble lignin, process water, and at least about 2% by weight of cellulosic fiber based on total weight of thick stock pulp, and adding at least one laccase enzyme and at least one organic polymer to the thick stock pulp to reduce the amount of soluble lignin therein. The organic polymer is chosen from cationic polymers, non-ionic polymers and combinations thereof.

Abstract: A method of measuring hydrophobic contaminants in a pulp slurry or a papermaking system includes the steps of providing an aqueous paper mill sample, filtering the aqueous paper mill sample to produce a filtrate comprising particles, and collecting an image of the particles in a measured volume of the filtrate. The method also includes the steps of analyzing the image to determine a size and morphology of the particles in the measured volume of filtrate, identifying spherical particles having a size of from about 1 micron to about 20 microns in the measured volume of filtrate, and quantifying a number of the spherical particles having the size of from about 1 micron to about 20 microns in the measured volume of filtrate. This method is useful for papermakers for deposition diagnostics, prevention, and contaminant control treatment optimization.
