Microplastic removal by aerated grit chambers versus settling …

The aerated grit chambers operate with short HRT and turbulent mixing, and thereby, they ought to capture MPs moderately. The aeration tanks of CAS system house microorganisms to remove dissolved organics from wastewater, and generate new microorganisms as biosolids. Hence, aeration tanks are not expected to remove MPs.
