    Abstract— Electrostatic technologies have been applied successfully in environmental remediation.  Electrostatic precipitation is an old technology with more than 100 year history, but still there are many possible applications to improve our environment including prevention of airborne infection. Non-thermal plasma has been evolved from ESP technology to treat gaseous pollutants in atmospheric air.  NTP produces highly reactive radicals (O, OH, etc.) that promote chemical reactions to remove gaseous pollutants. NTPs have been applied in removal of odor/allergen, volatile organic compounds(VOCs), etc. These applications require high energy efficiency in addition to low cost and reduced size.  To improve the energy efficiency, combination of non-thermal plasma and catalysts has been investigated, and has been applied in several commercialized products for indoor air cleaning and VOC decomposition.  DeNOx and deSOx can also be made.  Recently significant improvement of NTP processes has been made, especially combining with catalysts.  NTP can also be applied to liquid.  For example, nitric acid can be reduced to ammonia.  Wet-type NTP reactors are effective to clean exhaust gas, as well as cleaning of contaminated water.  In the lecture, novel possibility of ESPs, as well as generation and application of NTP will be introduced.

     Akira Mizuno received the B.S. degree in electronic engineering from Nagoya University, Nagoya, Japan, in 1973, and M.S. and Ph.D. degrees in electrical engineering from the University of Tokyo, Tokyo, Japan  in 1975 and 1978, respectively.

    He was with Ishikawajima-Harima Heavy Industries Company Ltd., between 1978 and 1981.  From December 1982 to April 1984, he was a Visiting Research Fellow with the Department of Physics, Florida State University, Tallahassee, where he was engaged in a project involving electron beam charging and precipitation of aerosol and industrial dusts.  In April 1981, he was with Toyohashi University of Technology, Toyohashi, Japan, and was a Professor with the Department of Ecological Engineering from 1994.  In 2003-2004, he was a Professor with the Institute for Molecular Research, Okazaki National Institutes, Okazaki, Japan.  Since 2004, he has been with Toyohashi University of Technology.  During 2002-2005, he was concurrently a Professor with the Department of Electrical Engineering, University of Tokyo. Since April 2010, he has been with department of environment and life sciences. 

    He has been involved in research on applied electrostatics and high-voltage engineering, which includes electrostatic precipitation, environmental application of plasma, sterilization, and other environmental technologies. He is also in charge of several projects of manipulation and analysis of single DNA molecules.

    Prof. Mizuno is a member of the Institute of Electrostatics Japan(vice president), IEEE (Fellow), etc. He is an editor of Int’l Journal of Plasma Environmental Science and Technology.
