This article describes the results of a pilot study conducted to compare the performance of a membrane air‐stripping system with that of packed‐tower aeration for removing volatile organic chemicals from drinking water. It was found that the mass transfer coefficients for the membrane system were generally more than an order of magnitude greater than those for the packed‐tower system. In particular, lower volatility compounds such as bromoform were very efficiently removed by the membrane. The data obtained for the membrane system were also compared with a predictive model developed from chemical engineering literature and verified in the laboratory.
