Research on Metal Ion Recovery from Chemical Nickel Plating Waste Liquid Based on Membrane Separation Technology

Kefan Chen

Abstract

This study investigates the application of integrated membrane separation technology for efficient nickel ion recovery from chemical plating wastewater. Utilizing ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO) membranes, the process achieved over
99% nickel ion removal while minimizing energy consumption and chemical use. The UF stage removed macromolecular organics, NF selectively concentrated nickel ions, and RO ensured high-purity water recovery. Economic analysis confirmed reduced operational costs and
waste generation. The findings support the industrial scalability of membrane technology for sustainable wastewater treatment and resource
recovery.
