The abstract describes the content of a paper that analyzes economic factors between running membranes beyond their useful life (if the membrane is still operational) and the cost of new membranes. It reviews the costs of operating membranes, including additional chemical cleanings, and the largest power costs. The decision, especially by a municipality, of expending the large, single amount for membrane replacement is reviewed against the improvements in operation and cost savings realized in lower operating pressures, membrane maintenance, assured throughput flow and chemical use. Even though the membranes are still operational, the economics may favor replacement. The Washington City, UT, 15 year membrane life is used for this analysis.
