The measurement error when calculating the bubble volume by using image analysis was estimated by taking a single bubble of known volume (0.02 × 10<SUP>-6</SUP>-2.00 × 10<SUP>-6</SUP> m<SUP>3</SUP>, or the volume equivalent diameter of 3.37-15.63 mm) and using a stereo visualization system with a high-speed camera. Previous studies calculated the bubble volume from images observed by the one-way photography method using the short-axis rotation of the bubble shape, which was assumed to have short-axis symmetry for approximation of the bubble shape to a spheroid. This study clarified the measurement accuracy for bubble volumes using one- and two-way image analysis methods. The results showed that the one-way method tended to underestimate the bubble volume when using the long-axis rotation, which approximates the bubble depth diameter by using the short-axis diameter, and overestimate the volume when using the short-axis rotation, which approximates the bubble depth diameter by the long-axis diameter. The measurement accuracy of the calculated bubble volume degraded for large bubble volumes. A one-way volume measurement method using a correlation equation was developed, and its accuracy was equivalent to the measurement accuracy of the two-way method using stereo visualization.

In the joint research and development of treatment systems of cooling water for cutting asphalt pavement surface with our authors' group, the liquid-solid separation technology by flocculating and settling technology, and the flocculants for the use of systems were developed. In this paper, the developed flocculating and settling technology and the flocculants are discussed first. Next, the demonstration tests of decontamination technology on the contaminated water in swimming pools in an elementary school located at Motomiya City, Fukushima Prefecture had been conducted by use of the stationary purification system of contaminated water and the flocculants compounding with or without iron ferrocianide developed by the preliminary test. It was clarified from the results that ionized cesium (Cs) rarely exists in the stagnant water in pools, ponds, lakes and so on at the time when nine months have passed since Fukushima Dai-ichi nuclear power plant accidents. Further, it is necessary to use the flocculants compounding iron ferrocianide in the case where ionized Cs exists in water. From the above-mentioned results, the following problems were pointed out: One problem was cyanide dissolution in the purified water and the other one was the dissolution from the dehydration sludge. Finally, the high-performance mobile purification units of contaminated water which is capable for carrying with trucks have been developed, and the demonstration test was performed in Minami-soma City, Fukushima Prefecture to purify the contaminated water in a pond and generated by the high-pressure water washing in a Public Hall. From the test results, it was made clear that the dehydration sludge separated by liquid-solid settling of the contaminated water of around 1,000Bq/<I>l</I> became a high radiation dose of about 185,000Bq/<I>l</I>.
