What exactly is validation?
Validation means demonstrating in black and white that a UV system effectively disinfects the water. Not only under ideal circumstances in a calculation model, but also in realistic, less favourable situations such as turbid water, variations in flow or a lamp approaching the end of its lifetime.
We prove performance through:
- Mathematical simulations
We model the water flow and the UV dose down to a detailed level, so we know exactly what is happening within the system.
- Biological practical tests
Our systems are tested with Bacillus subtilis in accordance with the European drinking water standards, the same standards used by water authorities and drinking water companies. We test under all conceivable conditions, including the end-of-life situation of the UV lamp. This is the point at which the lamp is least powerful, yet the system must still fully comply with the standard.
Only when all those tests are successfully completed is a system officially validated.
