ABSTRACT:
Sludge is composted by arranging the sludge in a pile over a conduit and air is forced into the pile in spaced time intervals and air is drawn from the pile into the conduit in alternate time intervals.
The perforated conduits are adapted to be placed under and extend the length of two windrow compost piles. A reversible blower is connected to blow air to and withdraw air from each of the conduits. The blower is timed and controlled to blow air from a first pile through the conduits and into a second pile in spaced time intervals and in alternate time intervals to withdraw air from the second pile through the conduits and into the first pile.
