Phosphates in Finishing Operations: Environmental Impact and Advanced Removal Strategies
White Paper
Phosphates play a key role in metal finishing operations, providing corrosion resistance and lubrication, but their environmental impact is significant. Excess phosphates in wastewater can lead to eutrophication, causing harmful algae blooms and water quality issues. Regulatory guidelines from the EPA limit phosphate discharge to protect water bodies.
Key considerations for phosphate management:
- Environmental Compliance: Exceeding EPA phosphate discharge limits can result in surcharges.
- Removal Strategies: Both chemical (e.g., calcium and iron precipitation) and biological methods (using polyphosphate-accumulating bacteria) are effective in removing phosphates.
Explore advanced removal strategies and innovations like non-phosphate alternatives by downloading our full white paper today.
