Metal Treatment and Hex Chrome Reduction with AquaPure
Case Study
In the highly regulated world of military metal finishing, compliance with stringent environmental standards is paramount. Pennsylvania’s well-known military metal finishing operation faced significant challenges in treating their hexavalent chromate rinses, which contained cadmium. Traditional methods were proving inadequate, risking non-compliance and potential penalties. The facility turned to Hubbard-Hall Inc., renowned for its expertise in solving complex wastewater treatment problems to address these issues. The Hubbard-Hall team devised a comprehensive solution that reduced hexavalent chrome and effectively treated cadmium to ensure all chelated metals were reduced to acceptable levels. They achieved remarkable results by utilizing Aquapure I-300, Aquapure P 601, and Aquapure AS Plus. This case study outlines the innovative process and highlights the product capabilities that brought the operation back into compliance, safeguarding the environment and the facility’s operational integrity.
- Aquapure I-300: Reduces hexavalent chrome at pH 6, eliminating the need for bisulfite at lower pH levels.
- Aquapure P 601: Metal precipitant ensures cadmium and other chelated metals are precipitated to meet discharge limits.
- Aquapure AS Plus: High-charged powdered anionic flocculant promotes rapid settling of solids, ensuring clear effluent.
