PCT No. PCT/JP96/02780 Sec. 371 Date May 19, 1997 Sec. 102(e) Date May 19, 1997 PCT Filed Sep. 26, 1996 PCT Pub. No. WO97/12077 PCT Pub. Date Apr. 3, 1997The present invention provides a method of and an apparatus for efficiently and economically discharging solid particles, which have sedimented on the bottom of a tank, out from the tank. A liquid is ejected from an ejector installed in the tank to move the sedimented solid particles to a predetermined place from which the sedimented solid particles are discharged out from the tank. Further, a solution which contains sedimentary solid particles is cooled and the solid particles are efficiently separated by a solid-liquid separator.
