Peracetic Acid (PAA)

Peracetic Acid:
Fast Knockdown.
Clean Profile.

Why PAA Fits Oilfield Water

Peracetic acid is a strong, fast-acting oxidizing biocide that delivers reliable microbial knockdown without the chlorinated byproduct profile of hypochlorite. In oilfield water, that combination is valuable — particularly in recycle programs where downstream chemistry, friction reducers, and frac fluids need to be protected from incompatible residuals. PAA decomposes into acetic acid, oxygen, and water.

The breakdown profile is clean, predictable, and well-suited to operators who want microbial control without complicating downstream chemistry.

What PAA Solves

Rapid microbial control in produced and flowback water

Sulfide oxidation and odor reduction in tanks and pits

Microbial knockdown ahead of recycle and reuse

Programs where downstream chemistry compatibility is a priority

How We Run PAA

PAA programs are designed around the operator’s water profile, logistics, and target residuals. PureLine Energy Solutions handles delivery, dosing, automation, and live monitoring — and pairs PAA with the rest of the treatment train (friction reducers, scale inhibitors, non-oxidizing biocides) when an integrated program makes sense.

PAA is also a strong candidate in combination programs, where a fast-acting oxidant is paired with a longer-residual chemistry like ClO₂ to deliver both knockdown and persistence.

Where We Run PAA

Produced water treatment for recycling

Above-ground tank treatments

Pit turns and water transfer programs
