Reducing Odors in Waste Rooms

Reducing Odors in Waste Rooms

Facilities, apartments and condominiums often suffer from odors from the garbage rooms that migrate from the holding area to the garage or on the floors through the chute system.

Different stand-alone systems can be used to eliminate these problems by destroying bacteria and removing chemical and biological odors. The objective is to rapidly recirculate the air in the room in front of UV-C to break down bacteria’s DNA, and in front of UV-V to oxidize the chemical decay molecules while minimizing the residual ozone.

Fighting Tobacco Smoke

Fighting Tobacco Smoke

Designated smoking areas, althrough typically spared from working and living spaces, often cause problems with air that may very well circulate in and out of these areas. The smoking area itself may be overwhelmed with cigarette smoke, causing smokers to seek alternative places to smoke.

Sanuvox Technologies offers two units that are effective at removing tobacco smoke from the air and reducing cigarette odors, as well as nicotine and smoke that are so problematic. Unlike conventional technologies, Sanuvox UV systems do not use costly carbon for absorption nor rely solely on filters, which easily become coated with tar and nicotine The proprietory process changes the molecular structure of the tobacco smoke into a fine powder, which is then captured on the filter media. It is recommended that the UV systems be sized to provide a recirculation rate of 6 to 8 air changes per hour.

THE EQUIPMENT

Stand-alone Sanuvair® 300 VOC or Sanuvair® 1000 VOC UV air purifiers that include germicidal and oxidizing ultraviolet lamps, prefilters and a main filter to capture nicotine and smoke. An optional VOC (Volatile Organic Compound) detector can be used with multiple lamps when the number of occupants increases.

Typical installation:

OPERATING THE EQUIPMENT

Sanuvox dual zone UV lamp will reduce odors, nicotine and smoke in the room through recirculation. With the optional UV-V lamp(s) and VOC detector, if the smoke level increases (because there are more smokers), the VOC detector will trigger the additional oxidizing lamp(s), then shut them off when the level decreases. The cycle is repeated, lowering the odor, nicotine and smoke levels, until the maximum reduction is reached.

UNDERSTANDING THE CHEMISTRY
Cigarette smoke is composed mainly of:

  • White ash
  • Nicotine molecules
  • Chemical by-products

Ash will be trapped by the pre-filters. Nicotine will be transformed into a type of yellow powder that will be captured by the prefilters and the main filter. The chemical by-products will be oxidized by the UV process: high frequency UV-V energy activates the organic molecules and accelerates the chemical reaction, resulting in the air being oxidized. Odors are oxidized by the process of photolysis that initiates the breaking of chemical bonds by the action of the ultraviolet light. The oxidation process will reduce odors and chemical contaminants by changing the complex molecular contaminants into CO2 and H2O

SIZING THE EQUIPMENT

Approximately 6 to 8 air changes per hour are required. This reduces the standard of fresh air required by two thirds.

An Sanuvair® S300 VOC unit (300 cfm) will be sufficient for a 1,920 cu.ft. room (12’ X 20’ X 8’) with 9.3 changes per hour.

An Sanuvair® S1000 VOC unit (1000 cfm) will be sufficient for a 9,600 cu.ft. room (20’ X 40’ X 10’) with 7.5 changes per hour.

WHERE TO INSTALL

Many buildings and facilities can be equipped with one of these stand-alone units, like eldercare homes, private homes, poker rooms and casinos, bingo halls, cigar bar, or smoking rooms.

Removing Ground Level Odors

Removing Ground Level Odors

Processing activities, as well as maintenance operations, can produce troublesome odors that may affect those working and visiting a site or facility. It 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 disinfection systems may be outfitted with special oxidation UV Lamp (185nm) that produce high levels of ozone (O3) to effectively combat odors emanating from these various types of applications. The self-contained systems can be located very close to the source of the odor alleviating the issue where it is most concentrated.

When the objective is to to substantially reduce odors generated by a sump pit, such as sewage ditch, sewer pumping stations, residual from ice scraping equipment (Zamboni), or grease traps, Sanuvox offers the right solution with its high efficiency patented air disinfection system.

THE 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.

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 Sanuvair® S1000 OZD INSTALLATION:

OPERATING THE EQUIPMENT

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.

PROCESS ON BIOLOGICAL AND CHEMICAL CONTAMINANTS
1-ACTIVATION PHASE: H2O+ O* –> OH* +OH*
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: OH*+P –> POH
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

SIZING
The stand-alone units will include an extra oxidizing (UV-V) lamp. In the absence of an ozone controller, a warning label must be provided to the user. Certain conditions may require up to four UV-V lamps in one unit.

WHERE TO INSTALL

Many buildings and facilities can be equipped with the S1000, like municipal sewage treatment plants, municipal pumping stations, ice-snow containment (pit) areas, hotels grease pits, and grey water treatment.

Extending Shelf-life & Delivering Exceptional Quality

Extending Shelf-life and Delivering Exceptional Quality

Mold and bacteria can severely impact the delicate payload on its way to storage facilities and retail stores. Ethylene off-gassing causes fruits and vegetables to prematurely ripen and age dramatically, shortening their shelf-life.

Sanuvox technologies offers an exceptional cost-effective mobile air treatment solution that easily incorporates into any truck or tailer designed to destroy airborne bio-chemical contaminants including bacteria, mold and ethylene off-gassing.

With its high efficiency patented air disinfection systems, Sanuvox offers the right solution when the objective is to destroy airborne contaminants, such as bacteria, viruses and mold that may affect the integrity of produce in transit. It also destroy ethylene, which causes produce to ripen faster.

THE EQUIPMENT

The 12V VP900 Interceptor is a small mobile air disinfection unit that can can be mounted in any location within the trailer or truck to sterilize airborne contamination and destroy ethylene gas. The UV system runs continuously bringing down contamination levels on an ongoing basis.

VP900 Interceptor:

OPERATING THE EQUIPMENT

The Interceptor recirculates the air, where:
1. The UV-C germicidal section of the UV lamp destroys airborne biological contaminants (viruses, mold, bacteria and spores).
2. The UV-V oxidizing section of the UV lamp reduces ethylene, slowing down the ripening process of vegetables and fruits.

SLOWING DOWN THE CONTAMINATION SPREAD WITH UV-C
Produce will degrade due to the rotting process. Rotting is caused by parasitic fungi and mold. Food deterioration begins with the breakdown of the cellular tissue by enzymatic action that allows the growth of microbes. Germicidal UV (UV-C) is extremely effective at preventing the reproduction of bio-contaminants. UV-C destroys airborne fungi, molds and their spores, limiting the contamination spread from one fruit to another. Meat, fish and chicken are especially vulnerable to airborne biocontamination. UV-C sterilizes the air, destroying contaminants as they circulate within the cold room.

RETARDING THE RIPENING PROCESS WITH UV-V
Photo-oxidation with UV-V can be used to reduce chemicals that trigger the ripening of fruits and vegetables. The life stages of a plant are influenced by plant hormones. An organic compound involved with ripening is ethylene, a gas created by plants from the amino acid, methionine. Ethylene increases the intracellular levels of certain enzymes in fruit and fresh-cut products, which include:

  • Amylase, which hydrolyzes starch to produce simple sugars.
  • Pectinase, which hydrolyzes pectin, a substance that keeps fruit hard.

UV-V oxidizes and thus neutralizes the ethylene molecules released by the ripening process, slowing down the spread of ripening to the surrounding produce.
This oxidation process breaks down ethylene into carbon dioxide and water vapor.
Ethylene C2H4 C2H4 + O* CO2 +H2O

WHERE TO INSTALL

The VP900 Interceptor can be installed in many places, like trucks transporting fruits and vegetables, cold storage rooms, groceries, fruit and vegetable retailers, or warehousing.

Purifying Air in Kennels & Veterinarian Centers

Purifying Air in Kennels and Veterinarian Centers

Illness among animals especially dogs can be significantly higher when many of them are boarded within close proximity, or kept within the same room or building. Airborne illnesses can easily be transmitted from one animal to another. Odors may cause issues when they migrate to other areas and affect staff and visitors.

Sanuvox UV systems are the ideal solution for destroying airborne viruses and bacteria, as well as reducing the concentration of unpleasant odors, such as ammonia produced by animals in kennels, shelters, pet stores and veterinarian clinics. Its proprietary system eradicates biological contaminants (bacteria, viruses, germs and allergens), and destroys chemicals and biological odors.

THE EQUIPMENT

Multiple application UV systems can be used for both stand-alone and duct-mount installations.

As stand-alone units, the P900 is equipped with an 80 cfm blower, the Sanuvair® S300 with a 300 cfm blower, and the Sanuvair® S1000 with a 1000 cfm blower. Sanuvair® S300 and S1000 also come with filters to capture particulates (pet hair, etc.). A dual zone UV-C/UV-V lamp is standard. An “adjustable” oxidizing lamp is available.

As an in-duct unit, the Quattro is installed parallel to the airflow and includes four UV-C/UV-V lamps, each with a one-inch section of oxidizing UV-V. Two of the lamp’s oxidizing sections are covered with removable foil, allowing for increased oxidation if necessary.

Typical installations:

OPERATING THE EQUIPMENT

Each unit treats the air through recirculation in two ways:
1. The Germicidal UV-C lamp portion destroys airborne biological contaminants (viruses, mold,
bacteria.)
2. The Oxidizing UV-V lamp portion reduces airborne chemical contaminants and VOCs through
photo-oxidation.

PROCESS ON BIOLOGICAL AND CHEMICAL CONTAMINANTS

1-ACTIVATION PHASE:  H2O + O* –> OH* +OH*
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: OH*+P –> POH
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 airborne contaminants are outnumbered by the activated oxygen atoms, then there will be formation of residual 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

CHEMICAL DECOMPOSITION:
Ammonia NH3+OH* –> N2 + H2O

WHERE TO INSTALL

Many buildings and facilities can be equipped with either the stand-alone disinfection units or the in-duct unit, like kennels, pet boarding and animal shelters, laboratories, veterinarian centers, and zoos and pet stores.

Disinfecting Locker Rooms & Bathroom Odors

Disinfecting Locker Rooms and Bathroom Odors

Lockers room odors are the result of perspiration which is excreted by the sweat glands in our skin. Sweat itself is not the source of the odor, but rather the off-gassing of the bacteria which feeds on sweat. The source of this unpleasant off-gassing can be found on occupants, clothes, towels and equipment as well as other soft materials.

The Sanuvair® S300 air purification system with HEPA filter is the ideal solution to reduce and elimitate unpleasant odors, such as in locker room and bathrooms. The proprietary Sanuvox process sterilizes and oxidizes bacteria, viruses, chemicals and odors, dramatically improving the air quality.

THE EQUIPMENT
As stand-alone units, the P900 is equipped with a blower of 80 cfm, the Sanuvair®S300 with a blower of 300 cfm, and the Sanuvair® S1000 with a blower of 1000 cfm. Filters (except on the P900) capture particulates (pet hair, etc.) while the dual zone UV-C/UV-V “adjustable” lamp disinfects the air.

The Sanuvair® S300 unit can be used as a stand-alone with optional intake and exhaust louvers or ducted using an 8-inch flexible duct with optional collars.

OPERATING THE EQUIPMENT

Untreated air is drawn into the inlet of the unit, purified with the germicidal / oxidation UV lamp, filtered and then exhausted. Recirculating the air in the room continuously reduces bacteria and odors, improving overall air quality.

WALL INSTALLATION, Sanuvair® S300:

SIZING THE EQUIPMENT
Approximately 6 to 8 air changes per hour are required.

A P900 unit (80 cfm) with a dual zone UV-C/UV-V lamp will be required for a 1,200 cu.ft. room (15’ X 10’ X 8’).

A Sanuvair® S300 unit (300 cfm) with a dual zone UV-C/UV-V lamp will be required for a 4,500 cu.ft. room (25’ X 20’ X 10’). Collars can be ordered to duct the unit using an 8-inch diameter duct, or an intake and exhaust louver grill(s), if the unit will be used as a stand-alone system.

A Sanuvair® S1000 unit (1000 cfm) with a dual zone UV-C/UV-V lamp will be required for a 15,000 cu.ft. room (50’ X 20’ X 15’). The system uses 2 x 8 inch inlets and 2 x 8 inch exhaust outlets (collars).

The unit should be positioned near the center of the room to be as effective as possible. Excluding the P900 unit, the two other units can be installed in the plenum above the ceiling or in an adjoining room and ducted with 8-inch round duct.

THE CHARACTERISTICS
All Sanuvox air purification systems are equipped with a dual zone “J” UV-C/UV-V lamp. All dual zone lamps have a maximum oxidizing UV-V section in order to minimize residual ozone. In situations where odors are more concentrated, it is possible to outfit the units (except in the P900 unit) with special lamps incorporating a larger section of oxidation, with the installer making the final odor adjustments on site.

WHERE TO INSTALL
Many buildings and facilities can be equipped with one of the stand-alone units, like team sport locker rooms, dressing rooms, fitness centers, laundry rooms and storage, or basements.
