Abstract:

This article is of crucial significance to the American water-supply industry. We say this because for the most part, American engineers are largely unfamiliar with European water-treatment practices, practices that at the present time, are far in advance of those in the U.S. In the most modern European drinking water treatment plants, technologies involving ozonization, activated carbon, chlorine dioxide, and Biological Activated Carbon are practiced. Chlorine dioxide produces long-lived residuals in distribution systems; ozone oxidizes organics without producing halogenated by-products; and the combination of ozone followed by granular activated carbon produces Biological Activated Carbon, which eliminates organics and ammonia and in many cases doesn't have to be regenerated for as long as two to three years.
