Abstract
High efficiency CCM post-treatment methods are described. A multilayer CCM mesh cage has multiple shelves. Each CCM is placed in between one or two pieces of mesh and loaded into the multilayer CCM mesh cage, which is made of mesh so that the acid or base can contact the CCMs. Multiple CCM cages can be soaked in an acid tank at the same time. A circulation pump can be included in the acid or base tank to circulate the acid or base during the CCM post-treatment. Large batch of CCMs can be treated simultaneously.
