A system both for the treatment of solid particles in a liquid and also for the treatment of a liquid by solid particles. The system includes a first scrolled barrel containing a liquid bath in which the treatment takes place, a second scrolled barrel attached to and communicating with the first barrel, the second barrel being constructed to prevent the free flow of liquid out of the bottom of the bath while at the same time allowing for the free passage of solid particles through the bottom of the bath, and a shaft for rotating the barrels. Both the first and second barrels are designed so as to insure a substantially uniform liquid level in the bath.
