Heavy metals removal · Rental clarifiers · Since 1985
We equip our clients to treat more for less.
Our patented iron co-precipitation process meets part-per-billion discharge limits for heavy metals, and our patented rental clarifiers put proven treatment on site in weeks, not years.

Our evolution
From 18 months and $1.8 million to two weeks and no capital at all.
Three real UniPure projects, each with guaranteed effluent quality and discharge compliance.
UniPure Process Technology
Iron does the heavy lifting.
Developed by Unocal’s Science & Technology Division, our patented iron co-precipitation process locks heavy metals inside dense iron solids — so they stay out of solution even when pH swings.
- Removes hexavalent chromium without reduction pretreatment
- Removes metals even with strong chelators present
- Lower operating pH: less base, longer equipment life
- Dense, stable solids that settle fast and dewater easily
- 01AssociateFerrous iron is added; heavy metals bind into its soluble chains.
- 02OxidizeIn the reactor, pH is held at 7.8 and air is sparged to turn ferrous iron ferric.
- 03OccludeMetals are enveloped in a dense iron matrix and can’t resolubilize.
- 04ClarifyHeavy, dense solids settle quickly and press easily.
About UniPure
We empower our clients to be good environmental stewards.
UniPure began by licensing Unocal’s patented metals co-precipitation process, then grew from process licensor to system supplier to build-own-operate contractor.
