Reducing Hexavalent Chrome in Wastewater
Case Study
Limco Airepair, specializing in the manufacture and re-manufacture of aerospace heat transfer components, faced a critical challenge: hexavalent chromium in their wastewater. Chromium is essential for creating durable surfaces and coatings, but its presence in wastewater, especially in its hazardous hexavalent form, required urgent action. Failure to control discharge levels risked facility shutdown. Hubbard-Hall stepped in to provide a solution.
Hubbard-Hall’s team conducted a full treatability study and recommended a two-pronged approach:
- Aquapure HQ: Reducing agent to convert Cr(VI) to Cr(III)
- Aquapure I-300: Ferrous coagulant to pull Cr(III) from wastewater
Download the case study to see how Hubbard-Hall’s innovative approach not only brought Limco’s wastewater into compliance, but reduced chromium levels to nearly undetectable levels, ensuring operational continuity and enabling further system upgrades.
