This paper focuses on several aspects of disinfection byproduct (DBP) control by nanofiltration (NF) membranes such as:
changes in natural organic matter (NOM) reactivity towards free chlorine between feed and permeate
waters;
relationships between trihalomethanes (THMs), haloacetic acids (HAAs), total organic halide (TOX), and dissolved organic carbon (DOC) in
chlorinated feed and permeate waters; and,
universalities in THM and HAA formation and speciation including bromine
incorporation and bromide utilization.
One important contribution of this work is that all nine HAAs (HAA9) containing
chlorine and bromine (species in HAA5 and CBr3COOH, CHClBrCOOH, CClBr2COOH,
CCl2BrCOOH) were analyzed. All bench-scale ICR experiments were
conducted using the Rapid Bench-Scale Membrane Test (RBSMT) methodology. One of the important components of ICR treatment studies were the SDS
testing of nanofilter feed and permeate waters. Deionized water (total dissolved solids (TDS) concentration less
than ~ 1 mg/L) was filtered at the start of each set of RBSMT experiments for
approximately 24 hours. Includes 31 references, table, figures.
