The effects of polydiallyldimethylammonium chloride (polyDADMAC) dose, epichlorohydrindimethylamine
(Epi-DMA) dose, and chlorine residual on NDMA formation in the
coagulation/flocculation/sedimentation drinking water treatment process were studied using
single-factor experiments. Influent water to a water treatment plant was used to conduct the
experiments. The goal was to determine whether the relationship between the tested factors and
NDMA yields followed linear or more complex relationships. It was found that an increase in
polymer dose resulted in a linear increase in NDMA formation. The addition of chlorine doses
exceeding the breakpoint resulted in a reduction in NDMA formation that followed empirically a
first-order reaction. Includes 25 references, tables, figures.
