The Importance of Replacement and Wear Parts

The best water treatment plant maintenance program includes replacing parts that wear out after long-term use. Those worn parts will need to be proactively replaced before they break and cause extended downtime. Replacement and wear parts can:

  • Restore performance strengths
  • Upgrade or retrofit clarifiers and thickeners
  • Meet the specifications of all mechanism types
  • Extend equipment service years
