My TAPPI Story: Dave Maddux
In TNPL, bagasses is stored by wet pile technology. Bagasses used for either chemical or mechanical pulping is at about 35% consistency, the remaining 65% being the water of 4.0 to 4.5 pH containing dissolved sugars. Use of Central channel water – rich in sugars and of high acidity as diluent adversely affects the optical properties and quality of pulp. Studies were undertaken to evaluate the influence of backwater on bagasses pulping including optical properties. Different ways of neutralising the residual sugars like, use of alkaline backwaters, washing and also the effect of the paper machine backwater of similar pH as that of bagasse handling backwater were studied in detail. Neutralisation as well as washing the bagasse improves the optical properties and the quality of the pulp.
