Abstract
Biodegradable organic matter in reclaimed water was evaluated to find strategy to control microbial regrowth. Assimilable organic carbon (AOC) was removed by activated carbon treatment, produced by ozonation, and stable in the other treatment processes. Higher AOC concentration was liable to cause microbial regrowth, and thus the regrowth can be controlled by reducing AOC concentration. Orbitrap mass spectrometer could successfully determine low molecular weight organic matters consumed by microbial regrowth by analyzing samples before and after the regrowth. The fate in the treatment processes was different among the compounds; they were either produced or removed by ozonation, or stable throughout the treatment.
