Aerated Grit Chamber - Wastewater Treatment - Beyond

2021-1-6 · Aerated grit chamber performance is a function of roll velocity and detention time. Adjusting the air feed rate controls the roll velocity. Nominal air flow values are 0.15 to 0.45 m3/min of air per meter of tank length (m3/min • m). The liquid detention time is usually about 3 min at the maximum flow. Length-to-width ratios range from 2:5 to ...

Aerated Grit Chambers in Wastewater | Hoffman & Lamson

Aerated Grit Chamber Processes. An aerated grit removal system removes particles by forcing water that has passed through bar screens into a grit chamber, which has air pumped into it. The air causes a spiral of water to flow through the tank and heavier particles are thrown out of the water's streamline. Eventually, after hitting the wall, the ...
