Abstract

Effectiveness of drinking water treatment, in particular pathogen control during the water treatment process, is always a major public health concern. In this investigation, the application of PCR-DGGE technology to the analysis of microbial community structures and dynamics in the drinking water treatment process revealed several dominant microbial populations including: α-Proteobacteria , β-Proteobacteria , γ-Proteobacteria, Bacteroidetes , Actinobacteria Firmicutes and Cyanobacteria . α-Proteobacteria and β-Proteobacteria were the dominant bacteria during the whole process. Bacteroidetes and Firmicutes were the dominant bacteria before and after treatment, respectively. Firmicutes showed season-dependent changes in population dynamics. Importantly, γ-Proteobacteria , which is a class of medically important bacteria, was well controlled by the O 3 /biological activated carbon (BAC) treatment, resulting in improved effluent water bio-safety.
