  • Design improvements, operational simplicity, advancements in new membrane materials, and competition in membrane industry have reduced both capital and operating costs of nano filtration (NF) and reverse osmosis (RO) systems for drinking water treatment applications. In Florida, the use of membrane technologies has increased to about 200 MGD today in comparison to 60 MGD in 1994. Currently, there are 125 membrane treatment systems in Florida with design capacities ranging from 800 gallons per day (gpd) to 25 MGD. A survey of economics of membrane treatment (NF and RO) facilities for drinking water treatment and concentrate management options were conducted for facilities located in Florida. Cost comparisons were based on data from different planning documents and plant surveys (Bergman, 1995; LEC, 2000; and budget data provided by the facilities). Since the capital costs depend on land cost, loan interests, consulting fees, design cost, pilot tests, costs of permits and other site specific factors; for accuracy of comparison, only the construction costs were considered for capital costs. ©2009 ASCE.
