Again thanks for all you advice, it is a big help. Hello, I run a .030MGD extended aeration activated sludge oxidation ditch ww plant. So far it has met it's limit exceeding well. It is a .045MG ditch. It had only 3 aeration discs when I started.
Bug life is good.
Many free swimmers but no stalked ciliates. Like I said the effluent is meeting limit very well. I have altered my aeration pattern several times. I usually clean the clarifier after wasting. This drops the level in the ditch and clarifier and prevents any loss of solid over the weirs asI clean the clarifier.
