Did you know that Total Dissolved Solids is the only measurement that accounts for both inorganics and organics?
 
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 eBook. 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 K‑PATENTS® SAFE-DRIVE Process Refractometer PR-23-SD is the ideal instrument for this application.

Real-Time Control of TDS in Brown Stock Washing

TDS has proven to be a reliable parameter for measuring Brown Stock Washing efficiency because it takes account of both the inorganic and organic fractions. Find out how Vaisala in-line process refractometers are able to quantify this process today!
