Slime in Aeration Cells of MLE process.

Not sure what it is, but we are getting a slime, in one train, that sticks well enough that it needs to be scrubbed off. This isn't the normal " hit is with a little soap" stuff. Almost need to scrape it with a knife. Kind of looks like polymer. There are blobs of it in the RAS and it has to be broken up to go down the sink.

DO's look normal in the Aeration tanks and anoxic cells look fine. Not foaming. Not really causing any problem...yet. Just don't know what it could be.
