ABSTRACT
The experience accumulated by the authors in the area of electroplating and metal finishing wastewater treatment has been acquired from a combination of hands-on experience, review of literature, mistakes (ours and others), equipment vendors, and peers within and outside the respective firms. This chapter identifies the procedures of designer apply in the orderly production of the process flow sheet or the Piping and Instrument Diagram (P&ID). It develops a "checklist" for use in the achievement of the design effort, particularly as it applies to selecting the treatment processes to be used. The procedure described is pertinent to both the cyanide destruction and chromium reduction process selection as well as applicable to any treatment process selection. The chemical destruction of cyanide by the alkaline chlorination process entails two independent chemical reactions: the oxidation of the cyanide to cyanate followed by the completion of the destruction to the end products.
