| Outline of Final Research Achievements |
I had to develop radioactive pollution water or clean water technology to environmental water around. I aimed at a high purge of cleanliness of steel of the thin pollution water disposed in quantities. Aggregate coagulant is used for conventional water purification, but there is a fault that the radioactive materials increase by an additive in its quantity, and the magnetic separations for which an additive isn't used are effective. There are no environmental standards on stainless steel and no problems with existence in the water, but radiation chrome included in stainless steel will be a problem. Stainless steel is usually non-magnetic, and is not easily collected by usual permanent magnets, but the particles in which the distortion is once introduced, it becomes weak magnetic substance. An adhesion separation can be effective according to intense magnetic field. A particle has to estimate according to the state of various magnetizing conditions.
