An apparatus for treating waste water comprising a tank having at least one waste water inlet for passing waste water into an inlet region of the tank, at least one waste water outlet for draining waste water from an outlet region of the tank, at least one first baffle between said inlet region and a settlement region of the tank, wherein contaminants having a specific gravity less than one are able to settle out from the waste water for subsequent removal, at least one second baffle between said settlement region and said outlet region of the tank, said apparatus further comprising a recirculation means for recirculating waste water from said outlet region to said inlet region of the tank, said recirculation means including a water inlet arranged in said outlet region of the tank, at least one water outlet arranged in said inlet region of the tank, and a pump for pumping water from said water inlet to said water outlet, characterised in that at least one water outlet of the recirculation means is arranged adjacent the surface of the waste water in the tank in use to deliver water in a stream parallel to the water surface.
