Simple grit chamber calculator tool that helps you to calculate volume of typical aerated grit chamber. In aerated grit chamber systems, air introduced along one side near the bottom causes a spiral roll velocity pattern perpendicular to the flow through the tank.
Formula:
V (ft3) = (peak flow rate (gal/day) × detention time (min) ) / (7.48 gal/ft3) × (24 h/d) × (60 min/h)
