Various combined biological reactor and membrane systems were examined to determine
the extent of organics removal possible for drinking water treatment without using
coagulant as an aid in a membrane type process. Two systems with bioreactors and
membranes with influent total organic carbon levels (TOC) between 2-5 mg/L were
studied. The synthetic water, representing a moderate to high TOC water, consisted
mainly of Aldrich humic acid. The remaining readily biodegradable components
represented by acetate, formate and formaldehyde. Reductions in TOC up to 60% were
possible. Calculated humic acid levels were decreased in one experiment from
approximately 2 mg/L to 1 mg/L through both biological degradation and membrane
processes. The acetate, formate and formaldehyde present in the synthetic water had
removal levels ranging from 70-100%. Includes 11 references, tables, figures.
