Municipal Applications

Peracetic acid (PAA) is a strong oxidant and disinfectant. It has proven to be a successful chlorine replacement, with oxidation potential higher than that of chlorine or chlorine dioxide.

PAA Applications for Muncipal Wastewater Treatment and Water Disinfection:

  • Replaces chlorine, sodium hypochlorite and is a low-capital alternative to UV, chlorine dioxide and ozone.
  • PAA treatment decomposes into biodegradable components and does not create chlorinated compounds or harmful disinfection by-products.
  • Disinfection performance not impacted by variability in nitrite or ammonia concentrations.
  • Can pass fish toxicity tests, showing no harm to aquatic life.
  • With the proper dose, PAA applications do not alter the water quality that affects the discharge limits.
  • Most applications do not require quenching of PAA residual.

Computational Fluid Dynamics (CFD) Modelling Capabilities

USP has unrivaled in-house CFD modeling expertise that can be used to optimize the injection, mixing and feed rates of PAA to meet the disinfection requirements of a facility.
