Brown Stock Washing (BSW) happens early in the pulping process, and its efficiency has a domino effect impacting the pulp mill’s cyclical economy. Proper BSW improves the performance of the oxygen delignification and subsequent bleaching stages by reducing the consumption of reagents. However, the washing process is complex, with many variables impacting the final product.
Inline monitoring of total dissolved solids takes account of both the inorganic and organic fractions, thus quantifying all washable solids. By monitoring TDS with a process refractometer like the Vaisala Polaris™ PR53SD, pulp mills can better understand the washing process and its efficiency.
