The COE Project

The Ministry of Education, Japan, started the program of "Center of Excellence" in 1995 to develop international academic centers in specific research fields. Under this program a COE project entitled "Establishment and Evaluation of Advan-ced Water Treatment Technology Systems Using Functions of Complex Microbial Community" was initiated in 1996 by Department of Urban and Environmental Engineering, the University of Tokyo. The project is expected to continue for 5 years, and aims to understand microbial structures and functions of biological water and wastewater treatment processes and to integrate engineering and microbiology for the development of efficient and safe water management systems.

Objective of Symposium

In the design and operation of wastewater treatment processes (WWTP), better and precise under-standing of biological nature and characteristics is necessary to meet with recent advanced and compli-cated needs such as nitrogen and/or phosphorus removal and bulking control. Innovative methods for microbial community analysis including vari-ous molecular techniques have been developed, which can be efficiently applied to analyze the microbial structures and functions of WWTP. The present symposium focuses on these new methodo-logies as well as traditional ones for microbial community analysis and their application to understand WWTP microbial communities.
