Electroless nickel (EN) is an autocatalytic reaction that deposits a uniform layer of nickel-phosphorus or nickel-boron alloy on the surface of a solid material or substrate such as metal or plastic. The multi-effect heavy metal collector imported from Germany can effectively treat chelated or non-chelated metals, and reduce the concentration of metals in the effluent to the 110-year regulatory standard. The picture shows chemical nickel wastewater. The nickel concentration has been reduced from 293 ppm to 0.03 ppm. After treatment, it can be mixed with other nickel-based wastewater for discharge.
