The purpose of this project was to evaluate the use of strong base anion (SBA)
exchange resin for the removal of dissolved organic carbon (DOC) from North Bay
Aqueduct (NBA) water. The NBA, part of the State Water Project, is a 27-mile
underground pipeline serving municipal and industrial water users in Napa and Solano
counties. Rapidly changing water quality conditions have historically been a tremendous
operator challenge for utilities treating water from the NBA, particularly in the
maintenance of stable coagulation conditions in the treatment process. The use of SBA
technology has shown considerable promise for significant removal of DOC from raw
water, resulting in reduction of coagulant and disinfectant demands while reducing
disinfection byproduct (DBP) formation. The uniform formation conditions (UFC) test
was used to evaluate the extent of DBP formation during the pilot testing. Includes reference, figures.
