Abstract
The cyclone degritter particularly suited for household use for receiving, degritting and discharging a water feed flow. The cyclone degritter comprises a pressurized housing containing a cyclonic degritter cartridge with a plurality of small hydro-cyclones arranged within a shell for collecting grit and an overflow vessel for directing clarified liquid to the housing overflow connection. In one form there is a bleed line from the top region of the shell or grit pot to the overflow for providing substantially improved recovery efficiency. In another form the cyclone degritter is provided with primary and secondary cyclone degritters with the primary set being used under conditions of low water flow while both primary and secondary sets are used for increased water flow.
