Full Description

The objective of this research was to evaluate a magnetic ion exchange resin for theremoval of natural organic matter and bromide as a disinfection byproduct controltechnology. Raw waters from four utilities in California were treated by the magnetic ionexchange resin followed by coagulation with alum. A parallel set of experiments wasconducted with alum coagulation alone. The raw and treated waters were analyzed fortotal and dissolved organic carbon, ultraviolet absorbance at 254 nm, bromide, andtrihalomethane and haloacetic acid formation potential. The waters were alsofractionated before and after treatment to determine the molecular weight distribution andhydrophobic/hydrophilic character of the dissolved organic carbon. Includes 18 references, tables, figures.
