Design of Innovative Flotation-Filtration Wastewater Treatment Systems for a Nickel-Chromium Plating Plant

摘要

The specific purpose of the report is to describe the chemical and physical methods incorporated in the pretreatment system, describe the modifications which will be made to improve the wastewater treatment system and to relate the methods and modifications to the operation of the total system. Special emphasis of the report is placed on presentation of: (a) detailed chemistry of nickel-chromium plating wastewater treatment; (b) conventional reduction-precipitation treatment system; (c) modified reduction-flotation treatment system; and, (d) innovative flotation-filtration treatment systems.
