Abstract
A cost breakdown for installing and operating an ozone as a sole cooling water treatment was evaluated for replacement of the multichemical treatment at the plant site with two approximately 2,000 tons cooling towers. Data provides a comparison when both towers will be treated chemically, with ozone and when only one tower will be converted to ozonation while the second one continues with multichemical treatment. The Level Annual Revenue Requirements (LARR) was applied in the evaluation process and EASOP version 4.0 software system of economic analysis was used for the calculation. There were two approaches applied in input of streams expenses. First, using the data input predicted by the service companies and the second one, the site most likely scenario, based on data obtained from more than two years of site technologies demonstration.
