Water Treatment Plant Process Evaluations and
Performance Optimization

A progressive series of studies have been conducted in conjunction with the staff of the Bloomington Water Department to improve treatment unit process performance, provide on-going operator training and develop comprehensive manuals on operation and maintenance for a plant treating water from Lake Bloomington and Evergreen Lake.

  • Direct microscopic count for treatment process evaluations.
  • Seasonal variations in source water quality
  • Water treatment plant particle removal efficiency
  • Particle counting; backwash; filter flow ramping protocol
  • TOC removal, seasonal effects on lime softening
  • Acidification protocol for turbidity exceedances
  • On-site operator training
  • Illinois EPA preparation and presentation
  • Evaluation of filter media condition, GAC replacement
  • Microscopy for process control: live/dead staining; Intel QX3+
  • Operations manual; Visitation-Day planning and programming
  • In-house operator training: softening and lime overfeed
  • Acidification: presentation at IPWSOA Conference
  • Clarifier performance study; sludge, grit removal protocol
  • Evaluation of Monty’s Llama (recirculating lime slurry degritter)
  • Evaluation of alternate sources of GAC
  • Development of plant operations manual
  • Taste-and-odor control alternatives
  • UV-peroxide oxidation of odor-producing compounds
  • Emergency response procedures: major power outages, lime feed failures, carbon dioxide tank leakage.
