Abstract

A particle separating apparatus is provided with a stock solution feeder (1) for supplying a stock solution containing particles, a bubble generator (2) for generating air bubbles to promote the separation of particles, a first separator (3) for separating the stock solution into a first concentrated solution and a first clear solution, a first discharge passage (4) for discharging the first concentrated solution separated by the first separator (3), a filtering device (5) provided inside the first separator (3) for filtering the particles in the first clear solution, a second separator (6) provided inside the filtering device (5) for separating the first clear solution into a second concentrated solution and a second clear solution, a second discharge passage (22) for discharging the second concentrated solution separated by the second separator (6) to the outside, and a clear solution guide passage (8) for guiding the second clear solution to the outside. Particles are effectively separated even in the case that a stock solution contains a large amount of particles having specific gravities similar to that of water.
