Enhanced coagulation has been identified as a treatment
technique for improving total organic carbon
(TOC) removal at conventional surface water
treatment facilities. The authors conducted this study
to evaluate site-specific strategies for optimized TOC
removal, taking into account the many other treatment
objectives affected by changing coagulant types and
dosages. The authors found that four coagulants commonly
used in conventional treatment processes successfully
met minimum regulated disinfection byproduct
(DBP) precursor control. Coagulant selection, however,
was based on other interrelated factors including
chemical cost or other secondary water quality treatment
goals.
Utility directors evaluating long-term DBP control
using coagulation will benefit from the comparative
coagulant cost and performance data presented. This
work illustrates that low-cost jar-testing techniques can
be useful in evaluating treatability costs and performance
relative to optimized coagulation. Includes 16 references, tables, figures.
