Patent ID: 8318026

Claim:
A system for controlling the sedimentation of sand or grit particles in wastewater in a grit chamber, comprising: a reservoir for containing the wastewater and having an inlet and an outlet; a device for creating turbulence in the wastewater contained in the reservoir, the device for creating the turbulence being configured to increase or decrease the turbulence in the wastewater; a water temperature sensor for determining the temperature of the wastewater; and a control unit operatively connected to the device for creating turbulence and operatively connected to the temperature sensor for controlling sedimentation in the grit chamber by increasing the turbulence of the wastewater in the reservoir in response to the temperature of the wastewater increasing and decreasing the turbulence of the wastewater in the reservoir in response to the temperature of the wastewater decreasing; wherein the device for creating turbulence is an air diffuser.
