Probably a stupid question regarding clarifier redundancy.  A plant has a flow of 9 MGD with 3 clarifiers.  Ignore redundancy.  I take this to mean if one clarifier goes down, the others DO NOT need to pick up the additional 3 MGD.  Therefore, solving a problem with this statement I would say they each run in parallel and take 3MGD.  Is this a correct assumption?

Thanks!

 
@BradyD, I think you are correct in your assumption. But, can you post the actual practice problem? 

 
You need to assume 1 is offline for backflush.  So, 9MGD through 2 clarifiers.
