Full Description

The primary objective of this work is to present a new model for estimating the capital costs of membrane facilities by establishing separate correlations for major cost components. This approach accounts for the individual economies of scale associated with different equipment and facilities and thereby considers an overall economy of scale for the entire membrane system that is a function of the design mix. The complete cost model is obtained by coupling the new capital cost model with equations for operating costs developed in a precious cost model. A secon objective is to utilize the newly formulated model to predict and analyze treatment costs for various raw waters and plant capacities. Includes 9 references, table, figures.
