| Research Abstract |
Innovative wastewater treatment technology by magnetic activated sludge process of easy operation and zero sludge emission was investigated. In this process, magnetic powder must be adsorbed on microorganisms for applying magnetic separation. A simple method for desorption of magnetic powder from microorganisms using magnetic traction was proposed in this research. Also, basic strategy of designing magnetic separators using permanent magnet for magnetic activated sludge and innovative processes for dye wastewater, high-nitrogen wastewater, stock raising wastewater purification, and advanced sewage purification were proposed in this research.
