Electroplating pickling, also called acid etching, uses chemical methods to remove rust and oxide films on the surface, leaving the surface of the workpiece in an activated state. The solution itself has no color. When the solution is blue, it means that the acid has expired and has been contaminated by ++. + ++ +++++++
The caustic soda neutralization method and lime neutralization method are generally used to treat electroplating wastewater. Caustic soda is easy to operate, but the cost is high. The cost of using lime is low, but the operation is complicated.
After years of research, Xi'an Environmental Technology Company has successfully developed a new method for treating waste acid from electroplating pickling, which uses a retardation separation method. Retardation separation technology is simple to operate and occupies a small area. Most of the separated impurities can be used for resource recycling and regeneration. It is the primary equipment to achieve zero-emission treatment.
This process has low operating costs and is suitable for enterprises with large processing volumes.
