Grit Removal: Wastewater Treatment Explained

Aerated systems employ a different approach for grit removal. In these systems, air is introduced into the wastewater to create a rolling motion. This motion causes the grit to settle at the bottom of the tank, while the lighter organic solids remain suspended in the wastewater. Aerated systems offer several advantages over the other methods.
