A method for treating waste water and sewage by introducing high pressure wash water or other fluids including gas into a housing of a hydro-cyclone and creating a cyclone with an enhanced and controllable vortex for increased removal of putrescible materials. Waste water and sewage is introduced into the housing and into the cyclone vortex. By the very high centrifugal force generated, suspended inorganic grit is quickly separated from the wash water and organic matter. The water with organic matter is then discharged typically out of the top of the housing, for returning to a water treatment plant for further processing. At this time, the separated inorganic grit, as a concentrated grit liquid, is typically funneled downwardly by gravity through a bottom of the hydro-cyclone housing for waste discharge removal.
