What cl of pollutant which goes through treatment process unchanged and shows in treated sludge?

Inorganics, synthetics, plastics. Synthetic fibers and plastics go through the system virtually unchanged unless mechanically filtered from the waste stream. There is a "pool" of floating shredded plastic floating in a dead spot in the Pacific Ocean between the Hawaiian Islands and the West Coast of the US that has grown to be about the size of Texas.
