With the increasing level of advanced removal of contaminants and recovery of resources in industrial wastewater treatment, the development of metallurgical and new material technologies, and the application of ion exchange technology in these fields, has become extremely important. However, in these fields, wastewater or feed liquid to be treated contains a high turbidity of solid suspended matters, a complex composition, and impurities such as high-valence metal ions, macromolecular organic matters, oils and the like which are harmful to resins. Causing the blockage of resin column, agglomeration of resin, bacteria growth, poisoning, scaling and pollution of oil/macromolecular organic matters, and the failure and rejection of resin in a short period. These problems have hindered the use of resins in these fields. It is therefore one of the key to solve this problem how to thoroughly revive the resin in an efficient way in case the resin is contaminated.
