The suspension method of solution or dispersion

The present invention, the solids content of the slurry suspension being processed in a bath, filtered through a washing or other purposes, then reslurry, dissolve, or practicing the dispersing operation, the bath a slurry suspension to provide a method for efficiently filtered in the tank including the vicinity of the nozzle flange. After separation of the solids content of the slurry suspension, a solvent was added and the slurry solids again reduction in dissolved or dispersed method for the same as that performed an operation to obtain the slurry suspensions inside the flanges directly in and / or on the same tank vessel, characterized in that separation of the solids is carried out, the suspension method of solution or dispersion.
