Abstract

Washing of by-product salts from chlorine dioxide generation processes is effected using a multi-stage decantation-washing operation. Metathesis processing of certain by- products by using a reactant solution in place of a wash liquid also is disclosed. The operation is preferably carried out by feeding an aqueous slurry of said solids into the uppermost of a series of superimposed compartments the washing solutions being fed into the lowest compartment; the liquid overflow from each compartment being fed to next higher compartment. <IMAGE>
