The ability to predict the optimum operating pressure allows selection of a membrane treatment system that minimizes total cost. This paper sets forth a model for estimating capital and operating costs based upon six basic variables. These variables are: pump and motor efficiency, electric cost, interest rate, amortization period, recovery rate, and membrane feed pressure. Equations are established for both capital and operating cost in terms of membrane feed pressure. These equations are then differentiated with respect to membrane feed pressure and set equal to zero to determine the membrane feed pressure at which the total cost of the system is minimized.
