Sodium Hypochlorite
Sodium Hypochlorite:
The Right Call When
It's the Right Call.
Why Hypochlorite Is in the Portfolio
Sodium hypochlorite (bleach) is one of the most widely used oxidants in the world for a reason: it is available, well understood, and cost-efficient at scale. For some oilfield water programs — particularly those with favorable water chemistry, accessible logistics, and clear downstream compatibility — hypochlorite is the right answer.
PureLine Energy Solutions doesn’t lead with hypochlorite, and we don’t avoid it. We deploy it where it fits, engineered into a program that controls residuals and protects the rest of the treatment train.
Global availability
Selective Oxidation
Cost-efficient at scale
Optimal applicability
What Hypochlorite Solves
General microbial control in fresh and lower-salinity waters
Programs where chemical supply chain and storage at scale are primary drivers
Bulk oxidant programs where cost-per-pound is a key economic factor
How We Make Hypochlorite Work in the Oilfield
Hypochlorite’s limitations in oilfield water are real. Performance drops as pH rises, organic load consumes free chlorine quickly, and chlorinated byproducts can complicate downstream chemistry. We design around those constraints with controlled dosing, real-time monitoring of free residual, and pairing strategies when needed.
When water chemistry or logistics make hypochlorite the wrong call, we say so — and recommend the chemistry that fits.
Where We Run Hypochlorite
Fresh-water treatment ahead of frac
Tank and pit programs with favorable chemistry
