A common interest in the pulp and paper industry is to find a new, holistic mill level solution that minimizes washing loss and consumes less energy and bleaching chemicals. In an optimal case, Brown Stock Washing (BSW) removes as much dissolved solids as possible while using the lowest amount of wash liquor or water.

By continuously and accurately measuring Total Dissolved Solids (TDS) at multiple points during BSW, pulp mills can:

• Increase production rates while maintaining stability
• Minimize steam and chemical consumption
• Improve washing efficiency and bleaching plant operation
• Avoid process disturbances, and
• Substantially reduce operating costs

Learn how to start monitoring TDS during BSW with Vaisala’s free eGuide. We’ll demonstrate why TDS is the most reliable measurement, how BSW optimization can create opportunities for all of the above, and why the Vaisala Polaris PR53SD Process Refractometer is the ideal instrument for this application.
