reuse applications have used mercury UV lamps containing
electrodes for the generation of UV radiation to meet
disinfection needs. These electrodes are delicately
constructed and their deterioration is the primary source of
disinfection system failures.
Euro-ATS’s a groundbreaking development in UV
disinfection is the use of microwave energy to power
electrodeless, high-output UV lamps integrated with
advanced system designs to meet ever more stringent
disinfection requirements. Microwave-powered UV systems
utilize microwave energy generated by a magnetron and
directed through a waveguide into quartz lamps. These
microwave-powered electrodeless lamps produce
predominantly monochromatic UV light, with the majority of
the UV output optimized at a 254 nm disinfection
wavelength.
Two distinct types of commercially available, microwave-
powered UV disinfection systems are available: modular,
vertical open-channel configurations for large-flow-rate
wastewater applications; and modular, closed-vessel
configurations for low-flow-rate wastewater and drinking
water applications.
Microwave-powered UV disinfection systems allow quick
start-up, longer lamp life, less fouling and higher overall
reliability, coupled with increased efficiency, safety and
flexibility in design.
Within the MicroDynamics system, the electrodeless lamps
warm up quickly and produce full disinfection capability
within 10 seconds. This often negates the requirement for
