Full Description

This article examines the technical and economic feasibility of incorporating ozone, granular activated carbon (GAC), or ozone-GAC unit processes into a conventional water treatment train to remove trace organic compounds, to reduce total organic carbon, and to control unpleasant tastes and odors. The results of this study indicate that the cost of preozonation is not sufficiently offset by lower GAC operating costs when removal of volatile halogenated organic compounds is the criterion controlling GAC service life. More conventional treatment options may offer equal system performance at lower total costs. For odor control, both GAC and ozone-GAC consistently performed well. The remaining issue is whether the consumer is prepared to spend additional dollars to achieve higher water quality goals. Includes 33 references, tables, figures.
