Counter Current Decantation
2021-5-4 Counter Current Washing and Leaching Calculations. Many processes in the hydrometallurgical and chemical industries require the separation of dissolved material from suspended solids. Counter current decantation (CCD) with thickeners is one of the methods generally used. The process engineer needs a quick and accurate CCD calculation method.
