Abstract Air-stripping in a packed column is sometimes used to remove volatile organic compounds from contaminated water supplies. Since the design engineer frequently uses data from a pilot air-stripping column to design a full-scale system, the suitability of such design scale-up was investigated. A total of 48 experimental runs was made in packed columns of four different diameters (6,12,24, and 57 in.) at air-to-water ratios ranging from 5:1 to 50:1. Water from the Village of Brewster, NY, well fields (contaminated with PCE, TCE and cis-1,2 dichloro-ethylene) was used. Various packing types (1/2, 1 and 3 in. saddles, 2 in. TRIPACKS) were used in the experimental runs. Generally, it was found that the mass transfer coefficient increased with column diameter, i.e., mass transfer coefficients obtained from a pilot column tend to be conservative.
