Abstract

The bacterial regrowth potential (BRP) of a range of Australian water supplies was determined following inoculation of samples with indigenous microorganisms. The bacterial growth in the sample was monitored by measuring changes in turbidity using an automated measuring technique which allows a detailed growth profile to be determined. Samples were taken from eight Australian water supplies where conventional treatment, consisting of flocculation, sedimentation and filtration is undertaken. Treated waters were found to have higher bacterial regrowth potential than raw waters for all except one supply where a granular activated carbon filter was included as the final stage.
