Nominal air flow values are 015 to 045.
. 3 Design aerated grit chamber for treatment of sewage with average flow of 60 MLD. Results of calculations led to the conclusion that the resultant bottom velocity of the properly designed aerated grit chamber should not exceed the nonsilting velocity for those. Grit chamber may be designed on a rational basis by considering it as a sedimentation basin.
In your design calculations you need to take into account the grit chamber volume air supply requirement dimensions and the peak flow grit quantity. Aerated grit chambers are typically designed toremove particles of 70 mesh 021 mm0008 in orlarger with a detention period of two to fiveminutes at peak hourly flow. Adjusting the air feed rate controls the roll velocity.
