This article presents the results of two pilot studies that evaluated trihalomethane (THM) removal by packed-tower aeration. One study was conducted on a lime-softened groundwater in southern Florida and the other on a conventionally treated northern California surface water. In spite of the differences in water quality, the results of the two studies were nearly identical. The data were used to determine constants of a correlation for the liquid mass transfer coefficient. The correlation was then applied to a process design model proposed by two of the authors to determine the most cost effective design for an 87 percent removal of bromoform. The authors recommend that a similar analysis be conducted on other commercially available packings. (Abstract also appears in Spanish) Includes 15 references, tables, figures.
