  • Apparatus for removing grit and grease from water
    Patent number: 6676833
    Abstract: A grit-and-grease removal system includes a grit channel for degritting water by promoting settling of grit to the bottom of the channel, the grit being removed from the bottom of the channel by a traveling bridge-type grit removal device supporting a submerged grit pump. The system further includes an elongate grease channel arranged to receive degritted water from the grit channel, and having a plurality of grease skimmer pipes extending across the channel above the water level. The grease skimmer pipes are spaced apart along the length of the grease channel, and each grease skimmer pipe includes a plurality of fluid discharge orifices or nozzles spaced along the length of the pipe and oriented to blow fluid obliquely onto the water surface in the direction of a discharge end of the grease channel so as to move grease floating on the surface to the discharge end.
