Peracetic Acid - Disinfectant for Industrial Wastewater
Peracetic Acid, or PAA, is an organic peroxide compound with the formula CH₃CO₃H. Peracetic
Acid is environmentally friendly as it hydrolyzes to acetic acid and
hydrogen peroxide in water. Peracetic Acid is a broad-spectrum biocide
with a fast reaction time (minutes rather than hours) and leaves no
harmful by-products. Peracetic acid is a strong oxidant and
disinfectant with oxidation potential higher than that of chlorine or
chlorine dioxide. PAA is available in the form of equilibrium mixture
which also contains hydrogen peroxide, acetic acid (vinegar) and water
as shown by the following equation:
CH3CO2H + H2O2 <–> CH3CO3H + H2O
Acetic Acid + Hydrogen Peroxide <-> Peracetic Acid + Water
Benefits of Using Peracetic Acid (PAA)
Highly effective microbial kill
No formation of chlorinated disinfection by-products
Stable in storage
Environmentally friendly decomposition products
Long shelf life (12 to 18 Months)
Minimal pH and temperature dependence
Safe and easy handling & storage
Examples of Microbiological Control Applications for Industrial Treatment
Sulfate Reducing Bacteria (SRB) Control
Broad
spectrum control for sulfate-reducing (SRB) and aerobic bacteria. Does
not interfere with other frac fluid chemistries. Environmentally safe
alternative to chlorine and glutaraldehyde.
Frac Water Ponds
PAA
has been shown to significantly reduce or eliminate Sulfate Reducing
Bacteria (SRB's) and their byproduct H2S, eliminating sulfide odor,
increasing worker safety, and protecting oilfield assets.
Wastewater Disinfection
Replaces
chlorine, sodium hypochlorite, and is as a low-capital alternative to
UV, chlorine dioxide and ozone. The PAA treatment decomposes into
biodegradable components and does not create chlorinated compounds or
harmful disinfection by-products.
Biofouling Control in Paper Machine White Water Circuits
Prevents microbial contamination in the recirculation water and removes slime.
