Description
The U.S. Environmental Protection Agency (USEPA) Information Collection Rule (ICR) included a nationwide assessment of thetechnical feasibility and costs to remove natural organic matter (NOM) disinfection byproduct (DBP) precursorsby granular activated carbon (GAC) and nanofiltration (NF). The resulting databaserepresents the most extensive evaluation of GAC efficacy for control of DBPs under real-worldconditions that is available today. The purpose of this study was to extend theanalysis of the ICR database to establish relationships between GAC service life and thefollowing key factors: source water type; feed water quality; GAC particle size; and,empty-bed contact times (EBCT). Two products of this study that drinking water professionals may find useful are:statistical models for GAC service time that can used in preliminary desktopevaluations prior to more expensive bench- or pilot-scale testing; and, information thatcan be used by utilities to optimize GAC treatment. Includes 14 references, tables, figures.
