Economic Analysis of Electroplating Discharges to Sewage Treatment Plants
Keyword(s):
Abstract A comparison of costs of implementing an advanced wastewater treatment system for a cadmium plating plant, versus the sludge disposal costs of the sewage treatment plant to which the plating plant is discharging its effluent, is described. An economic analysis spreadsheet approach using Lotus 1-2-3 is employed. A case study application demonstrates for overall society net benefit that it is cost-effective to initiate pretreatment at electroplating facilities which allows a municipal facility to dispose of its sludge on agricultural land rather than be required for landfilling. Sensitivity analyses to market interest rate, sludge production, sludge disposal fees and drag-out rates are explored.
