The experiments on sedimentation were carried out using the second-moromi, which was overflowed from a basket type-centrifuge and contained only fine particles. The size of glass vessel used for the experiments was 50×270 mm.1) The original second-moromi, containing 6.3g wet sludges per 100 ml, did not subside.When the moromi was diluted with water in various ratios, the setting velocities were accelerated.In all cases, there were lag periods followed by linear phases.2) Some effects influencing the setting velocities were investigated. As a result, it was found that the volume of the sludges had major effects on the settling velocity : When ploted by the settling velocity at the linear phases the velocity was inversely proportional to the volume ; however, when ploted by the time needed for the settling of 10 cm, these was a critical point where the settling time became suddenly rapid.Another effect on the settling was the viscosity of the liquids : the lower the viscosity the faster the settling was. On the contrary, the specific gravity had only a small effects.3) The density of the sludges was calculated to be about 1.018-1.024,which was smaller than the density of yeast. For this reason, we assumed that the sludges contain fibrous mycelia and some other lighter substances besides the yeast cells.4) From the sedimenting experiments the equivalent size of the sludge was calculated. The size was about 30-90 μ, which was higher than the yeast size by one order. It was presumed that the sludges in the diluted moromi were flocculated about 10 fold during sedimentation.
