Packed‐tower, countercurrent air‐stripping is widely used to remove volatile organic compounds from contaminated water. An air stripper is designed using a well‐developed mathematical model of the process. However, the number of variables in the model exceeds the number of constraining equations by two, with the result that a number of alternative air‐stripper designs are possible for a particular water treatment objective. To select one or several designs associated with minimum capital and operating costs, it is necessary to develop a large number of possible designs and to estimate the costs associated with each. The air‐stripper design and costing (ASDC) program, a microcomputer‐based public‐domain program, automates the iterative design and cost calculations and thus enables rapid, preliminary evaluation of alternative air‐stripper designs and associated costs. In this article, the design methodology and cost‐estimation techniques incorporated in ASDC are described, and ASDC cost predictions are compared with costs reported for actual operating air strippers.
