A Wastewater Treatment Device

A wastewater treatment device comprising:

• a vessel including an inlet for receiving an influent stream;
• a separator disposed within the vessel;
• a grit pot connected to the separator;
• a level sensor configured to output a signal indicative of the level of grit within the grit pot;
• one or more fluidizing nozzles disposed within the grit pot and configured to deliver a jet of fluid from a fluid supply to fluidize grit accumulated on the lower surface of the grit pot;
• an extraction outlet connected to a pump for extracting grit fluidized by the fluidizing nozzles;
• and
• a controller in communication with the level sensor, wherein the controller is configured to activate the fluidizing nozzles and the pump based on the signal received from the level sensor,
• wherein the controller is configured to activate the fluidizing nozzles when the signal is indicative of the level of grit within the grit pot being above a first predetermined threshold level.

A wastewater treatment device comprising:

• a vessel comprising an inlet for receiving an influent stream;
• a separator disposed within the vessel;
• a grit pot connected to the separator;
• a level sensor configured to sense the level of grit within the grit pot, and a support extending into the grit pot from outside of the grit pot, wherein the level sensor is movably connected to the support and is movable along the support between an operating position in which the level sensor is positioned within the grit pot and a maintenance position in which the level sensor is positioned outside of the grit pot so as to be accessible by a user.
