The integrated system of microfiltration and electrodialysis was proposed for wastewater reclamation, and the treatment performances were experimentally investigated with a pilot-scale system. The filterability of membrane and the long-term operational performances of the system were focused with real municipal sewage. The suggested wastewater reclamation system shows stable water quality during operational period over 6 months. Therefore, it is believed to be a useful system for reuse of wastewater and security of water resources.
