| Outline of Final Research Achievements |
Regarding super-fine powdered activated carbon, the mechanism of the Shell Adsorption Model to explain high adsorption capacity was verified. Low competitive adsorption, high removal of radioactive iodine, optimum particle size, and the reuse of spent granular activate carbon were revealed. Regarding poly-aluminum coagulant, effective species for low residual aluminum and high virus removal and their production conditions were found. Basic characteristics of normal and vacuum ultraviolet decompositions were studied. Degradation products were evaluated for their safety assessment. Regarding membrane filtration, lower membrane fouling attained by high-basicity poly-aluminum coagulant were related to aluminum particles size and silicate.
