Carbonate Removal Enhances Performance
Die Herausforderung
A German zinc-nickel plater sought to minimize electrolyte waste, embrace sustainability, and adopt advanced processes. Rising waste disposal costs and stricter environmental standards demanded a rethink of waste and wastewater management.
The challenge: Carbonates and sulfates accumulated in the ZnNi bath, compromising quality. The plater relied on the labor- and cost-intensive Bleed & Feed process to maintain deposition quality. However, this method generated excessive electrolyte waste, prompting the company to install a CarboPure unit for a more sustainable solution.
Die MacDermid Envio Lösung
The CarboPure unit removes carbonates and sulfates from the plating electrolyte, preventing salting and ensuring consistent, optimal performance.
Das Resultat
The CarboPure system delivered:
- Reduced costs and labor
- Savings on raw materials and energy
- Enhanced environmental and energy efficiency
- Improved solution conductivity, cutting energy use by 15–20%
- Reduced zinc content, drag-out, plating time, and current density
- Erhöhter Produktdurchsatz
- Significant reduction in zinc-nickel waste requiring external treatment
This innovative solution combines sustainability, efficiency, and cost savings, setting a new standard for zinc-nickel plating operations.
