Description
What is UV disinfection?
Disinfection generally means a reduction of around 99.999% of the pathogens present in the water. A dosage level of 400 J/m² is required to achieve this level of disinfection. The operational settings of the Bewades systems are calculated using numerical computer simulation, guaranteeing a UV dosage of at least 400 J/m². This dosage level has been biodosimetrically proved in the ‘N’ range systems and certified in accordance with ÖNORM M5873-1.
The number of UV disinfection systems installed is growing steadily and this ecologically-sound process is being used in an increasing range of applications owing to its extensive functionality and ease of use.
The BWT Bewades UV disinfection process will have no effect on the:
- Water hardness
- pH value
- Taste
- Smell
- Colour of the treated water
Bewades T
DVGW Certified disinfection performance (3rd party validated) confirmed by microbiological tests for all drinking water applications.
Intended use
The Bewades T UV systems enable efficient and safe UV disinfection of drinking water without the use of chemicals. UV disinfection with Bewades T UV systems does not change water chemistry or taste or smell. UV disinfection means a reduction of water-borne pathogens by 99.99% (4 log steps).
The Bewades T UV systems are type-tested according to ÖNORM M 5873-1 (2001) procedure B and certified according to ÖVGW QS-W 806 (2015) as well as DVGW worksheet W294 - 2 (01.06.2006).
Technical specifications:
- Unique dynamic lamp heating adjusts the lamp output in seconds and provides optimum disinfection even by rapidly varying flows and water temperatures
- Homogeneous UV dose, thanks to optimized flow behavior in the reactor, guarantees maximum flow output with a minimum number of lamps and minimum pressure loss
- Reduced life cycle costs due to long service life of Bewades T high-output lamps with low energy consumption and high UV output
