Mr. Ronan Boyle:

A network of pipes is fixed to the floor. They all run back to a compressor, which drives air through the network. Each area of the tank gets treated with air twice per day for roughly four and a half minutes for each location. That is the treatment of the manure. The system makes sure the manure is consistent as opposed to having solids at the bottom, water in the middle and a crusting on top. It will prevent crusting forming on the top where, typically, when one would go in with an agitator and break down the crust. It is like opening a bottle, one lifts the lid and suddenly hydrogen sulphide, nitrous oxide, N2O, and all the gases that, unfortunately, have claimed the lives of animals, are emitted.
