Abstract: A non-thermal plasma (NTP) system is used to treat air containing volatile organic compounds (VOC) and/or halogenated volatile organic compounds (HVOC), some of which may be odorous, and/or fine organic particulate (smoke) emissions to be released into the environment by commercial and/or industrial air exhausting, using one or more compound dielectric barrier discharge (DBD) devices that each incorporate a plurality of catalytically active DBD electrodes, catalytically active parts and dielectrics to develop one or more NTP fields so as to create sufficient reactive oxygen species, hydroxyl species and other highly ionized molecules and atomic species so as to cause the oxidation and/or reduction of VOC's and/or HVOC's and/or fine organic particulate contaminants in the air streams to be decomposed to simpler, non pollutant, non odorous compounds that can be subsequently released into the environment.

Abstract: Apparatus and method for precise and substantially continuous delivery of a substantially constant weight of conveyable material per unit of time from a bulk storage location includes a plurality of conveyors, preferably a pair of conveyors, with each conveyor of the pair suspended so that its weight is measured independently. The conveyors alternate filling and emptying, so that one fills while the other empties, and before the one conveyor fills completely, the other has emptied, so it can start filling while the filled conveyor begins emptying. This provides empty and full weight readings, while maintaining a continuous flow from the bulk source.

Abstract: An odor removal system to neutralize odors and VOC emissions released into the environment by commercial and/or industrial air streams utilizes Non-Thermal Plasma (NTP) to create a range of Reactive Oxygen Species (ROS) to cause the oxidation and/or reduction of odor causing molecules and VOC's. The ROS is generated by drawing atmospheric and/or odorous air through a Dielectric Barrier Discharge Plasma Generation Cell (DBDPGC). The gas is activated by passing it through the non-thermal plasma field in the DBDPGC, producing the ROS that are then immediately mixed into the odorous gas stream to be treated, or if it is the odorous gas that is passing through the NTP field, it is inherently mixed. When large volumes of gas, and/or extremely high odor load in combination with large gas volumes must be treated, multiple units can be combined in parallel to treat the gas. The DBDPGC has hermetically sealed hot electrodes and may be used in other applications.
