An eductor for mixing liquids and solid particles includes a nozzle, an initial mixing chamber, a first diffuser, an intermediate mixing chamber and a second diffuser. The nozzle includes a semicircular nozzle outlet that is offset from a centrally-located frst axis. Motive flow is accelerated through the nozzle through a first and second acceleration segment. Solid particles are added to the motive flow in the initial mixing chamber and directed to the first diffuser. Each diffuser includes an acceleration and a deceleration segment separated by an elliptically-shaped throat. The intermediate mixing chamber is located between the first and second diffusers. A method for mixing liquids and solids includes introducing a motive flow finto an initial mixing chamber, creating a vacuum in the initial mixing chamber to induce solids irto the motive fluid, providing a region of turbulence to enhance mixing of the motive flow and solid particles, and diffusing the motive flow to further increase boundary flow separation conducive to mixing.
