Ultraviolet (UV-C) disinfection provides an effective, chemical-free approach to controlling microorganisms in water and many types of liquid products. From drinking water and industrial process water to liquid sugar, syrups, juices, and specialty liquids, UV technology can be adapted to different flow rates and liquid characteristics.
However, not all liquids can be treated using the same UV system. Clear water, concentrated sugar syrups, and opaque or low-transmittance liquids have very different UV transmission properties and treatment requirements.
American Air & Water® supplies a range of commercial and industrial UV disinfection systems designed for different liquid-treatment applications. Our offerings include specialized thin-film UV systems for liquid sugar and viscous liquids, conventional in-line water disinfection systems, immersion UV equipment, and high-flow industrial solutions.
Whether you need to disinfect a water supply, treat beverage ingredients, or control microbial contamination in concentrated liquid sugar, selecting the correct UV configuration is essential.
Liquid sugar and concentrated syrups present a particular challenge for conventional UV disinfection. Their high concentration and low ultraviolet transmittance make it difficult for UV radiation to penetrate the liquid effectively.
American Air & Water offers specialized In-Line Liquid Sugar UV Disinfection Systems, designed specifically for these challenging applications.
Unlike conventional UV water reactors, these systems use a thin-film treatment configuration. The liquid passes as a thin layer over closely arranged germicidal UV lamps, maximizing exposure to UV radiation.
The design allows treatment of liquids with very low UV transmittance, including applications with UVT values below 1%, depending on the liquid and operating conditions.
These specialized systems are designed for applications involving:
American Air & Water offers several configurations to accommodate different production capacities.
The published model specifications include:
| Model | Reference flow rate* |
|---|---|
| IL-LS-300-5 | 10 GPM |
| IL-LS-300-12 | 35 GPM |
| IL-LS-5000-12 | 75 GPM |
| IL-LS-5000-20 | 100 GPM |
| IL-LS-6000-16 | 125 GPM |
| IL-LS-5000-36 | 150 GPM |
*These are published guideline flow rates at 67 Brix, not guaranteed treatment capacities. Actual performance depends on UV transmittance, liquid composition, concentration, flow conditions, and the required treatment objective. The systems are quoted according to the specific application.

For clear water and suitable liquid streams with sufficient UV transmittance, conventional in-line UV reactors offer a practical approach to continuous microbial treatment.
In these systems, liquid passes through a stainless-steel reactor chamber and receives exposure to germicidal UV-C radiation.
American Air & Water supplies several types of UV water-disinfection equipment, including systems from Viqua and other manufacturers.
The Viqua UV Pro NSF Standard 55 Class A systems are designed for specified water-disinfection applications.
The product family includes models with different treatment capacities and monitoring features.
The Viqua UV Pro30 NSF system, for example, is rated for up to 30 GPM at the specified UV transmittance and operating conditions.
These systems may be suitable for applications involving appropriately pretreated water supplies and water used in commercial or industrial operations.
For applications requiring higher water flow, American Air & Water offers additional UV equipment.
The Viqua VP950 high-flow UV water disinfection system is listed with a nominal flow capacity of 46 GPM, with a published operating range of approximately 35–60 GPM depending on conditions.
For smaller applications, the 15 GPM AAW5-Z22C rack-mounted filtration and UV system combines sediment filtration, carbon filtration, and UV treatment in a packaged configuration.
These systems illustrate the importance of considering the complete water-treatment process rather than UV disinfection alone.
Depending on the equipment and water quality, conventional UV water-treatment systems may be considered for:
System selection should account for water clarity, UV transmittance, flow rate, and the required microbial treatment performance.
Microbial growth can also be a concern in liquid storage tanks and reservoirs, particularly where liquids remain in storage or circulate through connected equipment.
American Air & Water offers Immersion UV Light Systems designed for installation in compatible liquid tanks.
These systems use submerged UV lamps protected by quartz sleeves and guards.
For certain applications, UV tank conditioners provide another approach. These specialized systems combine UV treatment with air filtration and ventilation components to help manage microbial contamination within suitable storage tanks.
Potential applications include:
The appropriate configuration depends on tank dimensions, liquid characteristics, circulation, and the desired treatment objective.

Some industrial facilities operate in environments where potentially explosive atmospheres require specialized equipment.
For these applications, American Air & Water offers Explosion-Proof UV Water Disinfection Systems.
These systems are intended for specified applications in industries such as:
Explosion-proof construction and certification requirements must be matched to the actual hazardous-area classification and installation. Equipment should not be assumed suitable for a hazardous location solely because it is described as explosion-proof.
UV-C disinfection works by exposing microorganisms to germicidal ultraviolet radiation. When microorganisms receive a sufficient UV dose, the radiation damages their genetic material and prevents them from reproducing.
The required UV exposure depends on the microorganisms being targeted and the characteristics of the liquid.
Several factors affect treatment performance:
For clear water, conventional in-line UV reactors can provide effective treatment when properly sized.
For concentrated sugar solutions, thick syrups, and other low-transmittance liquids, specialized thin-film systems may be necessary to achieve adequate UV exposure.
This is why choosing the right UV system for the specific liquid is so important.
American Air & Water® provides commercial and industrial UV disinfection solutions for water, beverages, liquid sugar, syrups, and specialty liquids.
