An Aerated Grit Chamber removes grit from wastewater streams. How it Works: Airflow is generated by a blower and is introduced into the Aerated Grit Chamber via a tube which is located near the bottom of the chamber, thereby creating a circular or toroidal flow pattern in the wastewater.The continuous rising flow deflects off an energy-recovery baffle at the liquid surface.ow it Works: Airflow is generated by a blower and is introduced into the Aerated Grit Chamber via a tube which is located near the bottom of the chamber, thereby creating a circular or toroidal flow pattern in the wastewater.
