Vortex system for separating particles from a liquid stream

A vortex system for separating particles from a liquid stream which comprises:

• an elongated, generally cylindrical chamber for positioning in a substantially vertical orientation in use;
• means at the upper end of said chamber for tangentially introducing a particle-bearing liquid into said chamber so that a vortex flow is established;
• an axial impeller at the upper end of said chamber for reinforcing said vortex flow;
• a plurality of injection jets along and through the outer wall of said chamber for introducing a fluid comprising a gas thereinto;
• first effluent means at the lower end of said chamber for removing gas and light, fine and buoyant particles from the axial region of said chamber;
• second effluent means at the lower end of said chamber for removing liquid and heavy particles from the outer region of said chamber;
• third effluent means at the lower end of said chamber for removing cleaned liquid from the annular region between said axial region and said outer region.
