UV-C systems for air treatment and emissions management

Mellifiq manufactures and develops advanced UV based air treatment systems for any application or emission challenge. Our Saniray Aurora series of complete UV systems provide high UV dose and carefully designed reactors and high quality lamps to ensure evenly distributed irradiance at a wide range of flows and contaminant loads. For low to moderate flows, optimal for a broad range of applications including pump stations, recycling plants or industrial emissions, the Aurora A-series provides high efficiency with a low footprint to handle at least 5,000 m3/h. The systems are designed for modular expansion and high capacity flexibility.

Saniray Aurora A-series design

We have designed the Aurora A-series in order to achieve small footprint, easy transportation and positioning on a EUR pallet, and simple lamp configuration and replacement. Connections are positioned on the top side of each unit with convenient sleeve couplings. Upon request, Mellifiq can also provide tailored cover plates with other types of connections such as flanges. Each unit can accommodate up to six low pressure UV-C lamps with a life time of at least 8,000 hours. Lamps are conveniently mounted and replaced thorugh single three-lamp modules, which allows for a configuration between 1-6 lamps.

All Saniray Aurora systems are delivered with a control unit for operational status and power distribution with required ballasts.

Typical application areas where the Aurora A-series may be incorporated may include odor control och VOC-borttagning in the biogasindustrin or municipal wastewater treatment plants.

Operational principles

The operational design the Aurora A-series is based on maximizing the irradiance distribution and hydraulic retention time in order to optimize the UV dose. Retention times are prolonged thorugh the use of a divider section which also increases the irradiance. For this reason, Mellifiq can offer the market’s highest dose per footprint ratio with flows exceeding 5,000 m3/h per units, depending on contaminant concentration.

Highly efficient UV-C treatment can applied both in the 254 nm range and if increased contaminant degradation rates are required, the Aurora UV-C systems can be delivered with bi-chromatic lamps at 185 and 254 nm to generate an Advanced Oxidation Process (AOP). Such deliveries can be done by combining our Ozonetech RENA Pro- ozonsystem, suitable for high concentrations and for pollutants with stable molecular structures.
