– high efficiency against a wide range of microorganisms including chlorine resistant ones (viruses and protozoa oocysts);

– no impact on physical, chemical and organoleptic properties of water and air; no by-products; no dangerous overdosing;

– low capital costs, power consumption and operational costs;

– UV systems are compact and easy to operate; no need for special operational safety precautions.

Main industrial available sources of UV radiation are low pressure amalgam lamps and mercury medium pressure lamps. Medium pressure lamp technology have higher power per lamp (several kW) but significant lower efficiency (9-12%) in comparison to low pressure lamp technology with efficiencies between of 35-40% and power per lamp up to 1000 watt.

UV systems equipped with amalgam lamp technology generally have a little larger physical footprint but they are significantly more energy efficient.

The design of UV application depends on the required UV dose, flow rate and physical and chemical parameters of media to be disinfected. The facility design criteria, flexible, economical and sustainable operation are also the decisive design parameters.
