Noble metals, rare metals, and valuable heavy metals
Nitric acid and other acids
Au, Ag, Cu, Ni, HNO3
Treatment of wastewater from the production process using it as industrial water.
1) The system is designed to achieve the quality required for the application.
2) The production line design can be modified to increase recycling rate.
3) 'Closed loop' system with zero discharge can be designed.
Rinse water recycle and treated wastewater recycle
Valuable elements from the waste liquid are collected or treated for reuse in the manufacturing process.
