Overview

Study demonstrates VUV and VUV with persulfate significantly reduce DBP precursors in algae-laden water, suggesting effective treatment strategies.

Key Points

  • The VUV/PS process effectively reduced disinfection byproduct precursors, removing 30% to 46% of dissolved organic carbon.
  • Fluorescence measurements showed more than 88% reduction in all fluorophores with VUV/PS, indicating high effectiveness.
  • Comparative analysis confirmed VUV and VUV/PS outperformed UV processes, achieving greater reductions in trihalomethane formation potential.
  • Noteworthy reduction of brominated DBPs, which are more toxic than chlorinated DBPs, raises concerns about water treatment efficacy.
