Patent ID: 6890429

Claim:
A system for treating waste water that includes liquid components and solid components, the system comprising: a skimmer apparatus comprising a holding tank for receiving the waste water and having a liquid outlet arranged below a level of an upper surface of the waste water in the holding tank through which liquid outlet the waste water is discharged from the holding tank, the skimmer apparatus further comprising a skimmer arranged for movement across the holding tank to skim floating solids from the upper surface of the waste water, and a solids receptacle for receiving the solids skimmed by the skimmer; a screening apparatus arranged to receive the waste water from the liquid outlet of the skimmer apparatus, the screening apparatus being structured and arranged to screen the waste water to remove coagulated suspended solids therefrom so as to create a solids stream and a liquid stream; and a biological reactor arranged to receive the liquid stream from the screening apparatus, the biological reactor comprising a tank for holding the waste water received from the screening apparatus, and an aerator disposed within the tank and operable to inject air into the waste water therein for biologically treating the waste water, the biological reactor having an outlet for discharging treated waste water therefrom.
