Drinking water solutions for the DBP formation potential - Water and Wastewater - Drinking Water

Problem: Drinking water plants that use chlorine for disinfection must ensure organic matter is removed before chlorination to limit the formation of harmful disinfection by-products (DBPs), most commonly Trihalomethanes (THMs) and Haloacetic acids (HAA5).

Monitoring UV254 provides the best indication of a water source’s potential to form DBPs. This is because absorbance at 254 nm has a bias towards aromatic organics, which readily react with chlorine to form DBPs.

  • Improved treated water quality
  • Reduced chlorine dosing for residual concentration requirements
  • Compliance with MCL for THMs and HAA5s
  • Improved public safety
