Operating Principle

The UV lamps inside a LIT DUV-A unit have a longitudinal geometry with lateral inlet/outlet flanges. Water enters the reactor and is exposed to the germicidal radiation. The UV lamps are isolated from treated water by special high quality fused quartz sleeves with a high ultraviolet radiation transmission coefficient (>95%). After UV treatment, the bacteria, viruses, pathogenic are inactivated and the water can be used for the designed application.

UV Dose

The DUV-A units ensures proper distribution of high UV doses over a wide range of capacities and water transmission values. The minimum required dose is guaranteed over the lamp’s operational life taking into account lamp ageing and quartz sleeve soiling. The supplied UV dose has been verified by third party validation tests.

UV sensor

As required by the various certification bodies (Russian Hygiene Governmental Authority, ÖNorm and DVGW), all DUV-A units are equipped with calibrated UV-radiation intensity sensors. This sensor provides continuous monitoring of the UV intensity and generates alarm signals if the UV intensity drops below the minimum required alarm level.
