Drinking water

Drinking water disinfection with UV radiation using wavelengths in the range of 240-290 nm is emerging as a sustainable alternative to conventional chemical disinfectants. One key advantage is that byproduct formation with UV doses of 400 J/m2 (= 40 mJ/cm2) is negligible.

In 2000, research proved this form of UV exposure was very effective against (oo)cysts of Cryptosporidium and Giardia. It showed that a 4 log-reduction (factor 10.000) of pathogens and viruses in drinking water was achievable.

The performance of 400 J/m2 and a 4 log-reduction can be verified by biodosimetric testing of UV systems using suspensions of bacterial spores with a known UV susceptibility (e.g. Bacillus sublilus spores or MS2 phages).

BestUV uses biodosimetric testing and computer models (CFD) to verify the hydraulics in each UV reactor and reliably predict its disinfection performance in drinking water applications.

For the lamp technology, BestUV uses both ‘state-of-the-art’ low-pressure (LP) and medium-pressure (MP) lamps.

BestUV’s drinking water disinfection systems have been validated and approved by major European water institutes.
