At the outset of a design study for a waste treatment system some of the relationships of the critical parameters are not well defined. Construction of a model in mathematical forms will allow some definition. Sensitivity analysis of the parameters and input variable will help identify those causing significant change in costs. This paper used activated sludge as an example. The activated sludge process is described in statements covering effects of waste character treatment rates, and construction and operational costs. The sensitivity analysis is performed on a computer using first a substitution of values method and then a pair by pair graphic display of cost response to parameter changes, for parameters identified as critical. The results of such an approach should assist designers in the delineation of control factors which should receive more intensive investigation and research to achieve optimum economy of a waste water treatment system.
