The metal uses a large amount of waste acid in the surface treatment process. When the metal in the acid solution reaches a certain concentration, the acid solution needs to be reconstituted and replaced because the treatment effect does not meet the process requirements. In this process, a large amount of waste acid is produced. These waste acid liquids contain certain concentrations of acid and metal, which pose certain threats to the environment and need to be treated. The waste acid washing liquid recovery and regeneration methods mainly include: heating evaporation method, special resin exchange method and diffusion dialysis membrane method. Kind. The heating and evaporation method has become inconsistent with the economical cost performance as the energy price rises. With the development of science and technology, the resin exchange method and the diffusion dialysis membrane technology have developed.
Suzhou Bojie Resin provides acid recovery resin, which can effectively recover acid and recycle it, saving production costs.
