1. The latest coating separation technology is used to recycle metal nickel. The high retention rate of divalent ions and the low rejection rate of monovalent ions are used to increase the concentration of nickel in the wastewater to meet the requirment of recycling nickle from wastewater.

2. After nickel recycle treatement, the wastewater can be reused for 80% of the water required in production, meeting the requirements of safety, energy conservation and environmental protection
