IASP Biosolids Composting Pilot Study
These 6" diameter pipes have air holes.
These pipes will release oxygen into the pile.
The pipes will track beneath the heap.
Wood chips allows the pile to breathe.
Powerful fans will force the air through.
The layer of wood chips is very thick.
The fan(s) are set to blow at intervals.
One fan can aerate one or more piles.
More wood chips cover the pipes and also help keep air holes unclogged.
Woods chips are vital to the composting process.
Micro-organisms and bacteria use the oxygen.
The compost pile is built with many layers.
Turning and watering the heap often is necessary.
Weights — Weights will hold down the compost cover.
Sealed pipes — Sealed pipes with water or sand also work as weights.
The Compost Cover is draped and weighted down.
The fan fills the Compost Cover(s) with oxygen.
This is an odor evaluator flux chamber.
Nitrogen voids air in the flux chamber.
The temperature is constantly monitored.
These are different monitoring equipment.
Odor evaluator
Compost Covers are weighted and sealed.
Odors are contained, decomposition begins.
