Development of partitioning method. Filterability of slurry formed in denitration of simulated high level liquid waste

Abstract

The filterability of slurry formed in the denitration of a simulated high level liquid waste (HLLW) was experimentally examined. The particle size distribution of the sludge greatly affected the filtering characteristics of the slurry. If the slurry contained fine particles of around 0.1 {mu}m diameter, it was difficult to separate the solids by a constant pressure filtration. On the other hand, the slurry without fine particles could be smoothly filtered. Most of the fine particles of around 0.1 {mu}m diameter were formed during the denitration of the simulated HLLW. The formation of these fine particles was effectively suppressed by following methods: (1) refluxing the simulated HLLW before denitration until the total heat input exceeds 5.7 x 10{sup 6} [J/L] or (2) adding the total heat input more than 1.1 x 10{sup 7} [J/L] to the simulated HLLW during the denitration. The effect of (1) was observed independent of the liquid volume in one batch reflux operation. (author).
