Title: Innovations by Carol S Greer

Introduction

Carol S Greer is a notable inventor based in Lisle, IL (US), recognized for her contributions to the field of water treatment and paper mill processes. With a total of 5 patents, she has made significant advancements in methods for removing contaminants from water, particularly in the paper industry.

Latest Patents

One of her latest patents is titled "Enhanced removal of hydrophobic contaminants from water clarification." This invention provides a method for removing secondary fiber contaminants from paper mill process waters. The process involves adding a polyvinyl chloride, a cationic polymeric coagulant, and a polymeric flocculant to the contaminated water. This combination agglomerates the contaminants into larger particles, which can then be effectively removed using a dissolved air flotation clarification technique. The addition of particulate polyvinyl chloride enhances the effectiveness of the removal process by preferentially coating the contaminants.

Another significant patent is the "Method for reducing pitch deposition using copolymer of N-vinyl acetamide." This invention addresses the issue of pitch in paper mills by treating the systems with a water-soluble polymer that contains a lower alkyl N-vinyl amide or a hydrolyzed lower alkyl N-vinyl amide. This innovative approach helps in controlling pitch deposition, thereby improving the efficiency of paper production.
