Comparing Ozonation and Membrane Separation for Color Removal and Disinfection By‐product Control

Abstract

This article reports the results of applying ozonation and membrane treatment to a groundwater source containing significant levels of color and disinfection by‐product (DBP) precursors. Although both treatments provided effective removal of color, greater levels of DBPs were associated with the ozone treatment—after postchlorination. The effective DBP precursor removal provided by membrane separation of this groundwater source indicates that membrane processes are a promising treatment technology for complying with the more stringent DBP regulations that are expected in the near future.
