Ground Level Odors19 January 2017
Processing activities as well as maintenance operations can produce troublesome odors that may affect those working and visiting a site or facility and may even cause problems for those living in the underline community. These applications include: sewage treatment facilities, sump pump operations, excavation, pumping stations, arena ice pits, grease traps etc.
Sanuvox UV Systems may be outfitted with special oxidation UV Lamp (187nm) that produce high levels of ozone (O3) to effectively combat odors emanating from these various types of applications.
S1000FX w/special Oxidation UV Lamps
- Self-contained system can be located very close to the source of the odor alleviating the issue where it is most concentrated
- UV Lamp ozone « arcing » systems. UV Lamp O3 production is not sensitive to relative humidity and there is no acid by-products produced through the oxidation process.
GROUND LEVEL ODORS
GOAL: To substantially reduce odors generated by a sump pit such as: sewage ditch, sewer pumping stations, residual from ice scraping equipment (Zamboni), grease traps, etc…
EQUIPMENT: Stand-alone units that will either:
- process air through recirculation in a room or
- inject a small quantity of ozone directly into the specific containment device to reduce odors
NOTE- an ozone controller can be used to limit the residual
ozone outside of the containment area to a concentration
level lower than the ASHRAE limit (0.05ppm).
Typical S1000FX INSTALLATION
OPERATION: The unit purifies the air through recirculation in two ways:
1. The UV lamp germicidal section destroys biological contaminants (viruses, fungi, bacteria) moving through air.
2. The UV lamp oxidizing section reduces the chemical components in the air through photo-oxidation.
GENERAL: SANUVOXTM PROCESS ON BIOLOGICAL AND CHEMICAL CONTAMINANTS
1-ACTIVATION PHASE O2+ O* –> O* +O*
Ultraviolet photon energy (170-220nm) is emitted from a high-intensity source to decompose (break-down) oxygen
molecules into activated monoatomic oxygen. The rate of production or effectiveness of this process depends on the wavelength and intensity of its source.
2-REACTION PHASE: O*+P –> PO
The activated oxygen atoms (O*) are then mixed in the airstream; the process will react with any compound containing carbon-hydrogen or sulfur, reducing them by successive oxidation to odorless and harmless by-products. If the activated oxygen atoms outnumber airborne contaminants, there will be the formation of ozone (O3) which will occur following the oxidation of normal oxygen molecules (02).
3- NEUTRALISATION PHASE: (also GERMICIDAL) O3+UV(C) –> O2+O*: O+O –> O2
The stand-alone equipment except for the P900GX-SP (S300FX-GX, or S1000FX-GX ) will include an extra oxidizing (UVV) lamp.
In the absence of an ozone controller, a warning label must be provided to the user. Certain conditions may require up to four UVV lamps in one unit.
