Technology for Recycling Nickel in Wastewater – Reusing water, nickel recovery and asking benefit from wastewater

The technology of “recycling nickel from wastewater” can be used to recover more than 90% of nickel contained in wastewater (reducing nickel discharge), recycle more than 70% of water, and the running state of its on-site equipment can be monitored by utilizing sensors and information technology through GPRS to guarantee the quality of recovered water and raise the recovery rate of nickel. Now, There are more than 500 sets of the equipment being used in more than 200 enterprises Shanghai and Yangtze River Delta Area, such as Shanghai Mint, Shanghai Aircraft Factory, SKE, Mitsui Hi-tech, Toyota Synthesis, Sun & Moon Light Semiconductors, Yinai Sanitary Products, etc. We have recovered a large quantity of valuable nickel, at the same time, saved a huge volume of water, realizing multi-wins between our company and users in economic, social and environmental benefits.

This project has acquired 19 patents in total, gained support from the State Scientific & Technological Ministry, and been listed in the National Hi-tech Torch Plan, Shanghai Cleaner Production Technique, The project was listed in the “National Clean Production Guiding Technologies Catalogue (2009) ” (only 4 such projects in Shanghai).
