特殊セラミックスの流動電解による水処理法

Recently, techniques of controlling the environments of growth and development in nutriculture in green houses and so forth have been much expected. For this purpose, the assurance of good-quality raw water and environmental protection are important problems to be solved.
This study was conducted, directing a major attention to the fact that some of ceramics produced from silicate minerals as raw material have electric functions such as electric insulation, dielectric, and piezoelectric properties. Stable granular ceramics having electric charges at the surface were produced, by using the natural raw materials of silicate minerals having excellent mouldabilities and sintering properties. It was attempted to produce water having functions, by using effectively the electrochemical energy of the ceramics with an efficient water treatment device in which the ceramics were fluidized in water, differently from conventional systems. As the experimental results, the conductivity of the water treated with the ceramics was not changed, but the oxidation-reduction potential and also the pH and the dissolved oxygen concentration were changed. Then, improvements in water quality and proper oxidation-reduction potentials of water, which will contribute to the ecosystemic agriculture, were obtained.
