Unit and Total Cost Functions for Water Treatment Based on Koenig's Data

Abstract

Whether a water treatment plant is installed as an independent facility or as an addition to an existing system of such plants, the determination of its capacity depends to a great extent on its total cost, which is composed of the amortization of capital investment and the fixed and variable operating costs. This total cost is formulated as a function of capacity and use rate on the basis of data reported by Koenig on surface water treatment.
