Improving Productivity and Quality by Controlling Organic, Inorganic and Microbiological Deposits

Chapter

Abstract

The modern papermaking process is very sensitive to disturbances. The formation of deposits is one of the most important factors limiting the productivity on a paper machine today. Further, paper defects such as breaks, holes and spots very often caused by deposits represent one of the most common complaints of a user/buyer of paper. The origin and mechanism of deposit formation and how these deposits affect quality and productivity are reviewed in this chapter. The most commonly used methods to eliminate or reduce deposition are summarised for each type of deposit. The guidelines are intended to give pragmatic advice for the realist working to maximise productivity and quality in real-life situations. This chapter reviews the source and control of paper machine deposits and the alternative methods of application of chemicals to minimise/eliminate these troublesome deposits. It is intended to give pragmatic guidelines for the realist working to maximise productivity and quality in real-life situations.
