Comment: The initial reduction is by aerobic digestion. Final reduction is achieved through running the
digested sludge through a furnace at consistent heat for a controlled time. The heat reduces the
sludge to a Class "A" residual product that is utilized by local farmers and the public.
Sampling
Describe sampling:
Composite sampling is performed at the discharge point of the furnance to make sure reduction has been
achieved.
Is sampling adequate?
Is sampling representative?
Yes No NA NE
