Air flow system for waste treatment systems

An air flow system for a waste conveyor, comprising a conveyor enclosure having a bottom side configured for being mounted above a conveyor surface at a predetermined surface clearance;

• one or more air flow unit enclosures mounted to the conveyor enclosure, wherein each air flow unit enclosure comprises an air flow unit having an air intake and air exhaust,
• wherein each airflow unit enclosure comprises a divergent channel having a channel intake end fluidly connected to the air exhaust and a channel discharge end configured for providing a stream of air toward the conveyor surface,
• wherein the divergent channel comprises a widening cross section in a downstream air direction between the channel intake end and the channel discharge end of the divergent channel, and wherein the divergent channel is arranged at an angle larger than 0° and smaller than 45° degrees with respect to the bottom side of the conveyor enclosure.
