  • How effective is a peracetic acid disinfection system?
  • Shigella (4Spp.) The effectiveness of a Peracetic Acid (PAA) disinfection system depends on the characteristics of the wastewater, the concentration of PAA, the amount of time the microorganisms are exposed to the PAA, and the reactor configuration.
  • Can peracetic acid replace halogenated disinfection chemicals?
  • existing wastewater treatment facility has become apparent. The use of peroxygen chemical compounds has been practiced for years in Europe, but in the last several years water treatment companies have been considering the use of peracetic acid (PAA) as an alternative to halogenated disinfection chemicals (such as chlorine based products).
  • What are the disadvantages of peracetic acid disinfection?
  • Major disadvantages associated with peracetic acid disinfection are the increases of organic content in the effluent due to acetic acid (AA) and thus in the potential microbial regrowth (acetic acid is already present in the mixture and is also formed after peracetic acid decomposition).
  • What is the difference between peracetic acid and performic acid?
  • Peracids have gained interest in the water treatment over the last few decades. Peracetic acid (CH 3 CO 3 H) has already become an accepted alternative disinfectant in wastewater disinfection whereas performic acid (CHO 3 H) has been studied much less, although it is also already commercially available.
