Abstract
In this study, the biomass and the growth rate of attached algae were monitored to compare the characteristics of attached algae growth between two materials, ceramic and cement. Microbial community analysis was also performed to examine attached algae and microbes in the drainage canal of sedimentation basin in a water treatment plant. The growing rate of attached algae in accumulated areas was faster than early growing areas. In addition, the biomass of attached algae growing in the cement materials was evidently lower than the ceramic ones. These results suggest that ceramic materials can be applied to the water treatment plant for improving water quality and maintenance. From microbial community analysis, the dominant quinone type of attached microorganisms in the water treatment plant was plastoquinone (PQ)-9 and vitamin (V) K-1. Especially, PQ-9 increased gradually based on the accumulated period. Although the materials and the total biomass were different, the comparison between cement and ceramic quinone analysis implies that microbial ecology in the same area would not be changed distinctively.
