Alternate Positive (+) and Negative (-)

All Positive (+)

All Negative (-)

Air flow is computer controlled to be all positive, all negative, simultaneously positive and negative, or alternating between all modes of the air flow direction to automatically create a self cleaning action. Negative air flow is collected hot within the compost mass to improve odor processing efficiency.

	The rows of lances create a short horizontal air flow path between the multiple pressure/vacuum zones inside the compost mass to assure of uniform composting. Oxygen starved pockets (odorous anaerobic zones) in the bio mass are eliminated by diffusing three dimensionally throughout the biomass. This efficient air distribution system assures of rapid uniform composting.

	Controlling odors should be of prime concern for any composting facility. Potential odors are controlled using a comprehensive design approach that takes all potential odor sources into full account and designs to collect all odors. It also requires an efficient compost process, an effective air collection system, an efficient odor removal process for the collected air.

	Uncontrolled odors will interfere with the enjoyment of life adjacent to any compost facility, as many composting operations have found out the hard way; being forced to shutdown.

It becomes very difficult and costly to build and operate an odor control system that has to process large volumes of diluted odorous air. The AirLance™ system offers several process advancements which reduce the amount of air leaving the facility to a small fraction of other systems.
