Monitoring and Control Strategy

Monitoring of the chemical program(s) is completed using a variety of methods and/or combinations.

  • Microbiological enumeration: plate counts, dip slides
  • ATP and ORP monitoring
  • Visual inspection of treated systems and storage
  • On-site microscopy analysis
  • Detailed laboratory deposit analysis

Control strategy is based on a clear understanding of customer requirements and measurements, allowing service representatives to make necessary adjustments to programs using monitoring data/information as a guide.

  • Reduce or eliminate spoiled slurries additives
  • Reduce off-quality paper product due to microbiological deposits and holes
  • Improve runnability of process
  • Improve performance of additives, pigments, and wet end functional chemistries
  • Increase length of time between system and storage cleaning
