The smell in the secondary tanks - aeration - is surprisingly inoffensive. The smell for the tertiary tanks can be even a little sweet smelling. In the digestion tanks it's pretty much odorless.
It depends on the input of course. I presume it's mostly food scraps and human waste. Nothing industrial.
