Floating sludge: As the colder water sinks to the bottom of the lagoon, it dislodges the solids settled at the bottom, which have been quietly anaerobically digesting.The anaerobic digestion process releases gas as a byproduct, which becomes entrained in the sludge. Once dislodged, the gas trapped in the sludge causes it to rise from the bottom of the lagoon and float.
