Procedure
recycling the first stage acidic filtrate back to said chlorine dioxide generator and dissolving said first stage sodium bisulfate crystals in H2O to create a second stage solution for a second stage evaporator/crystallizer and heating said second stage solution to a prescribed temperature under a partial vacuum for a predetermined period of time to reduce the solution volume and then cooling said solution in the crystallizer to produce second stage sodium sesquisulfate crystals from which the second stage acidic filtrate is separated and recycled to said first stage evaporator/crystallizer, and
