UV DISIN­FEC­TION

UV DISINFECTION

Harnessing the power of the sun to produce clean water without using chemicals.

Water is our most important food and naturally contains bacteria. Most of these are harmless, but there are also microorganisms that can multiply quickly under certain conditions, becoming a problem for human health. For example, self-sufficient customers who have their own well or spring can find their supply is increasingly contaminated with germs. UV disinfection systems from BWT are an environmentally friendly solution that reliably reduce germs and viruses in water.

It is strongly recom­mended that water sources other than that from the public drinking water supply, such as well or spring water is tested by an autho­rised labo­ra­tory. The water should then be treated appro­pri­ately before being used for drinking or bathing.

BWT offer a range of solu­tions for those home­owners who rely on these alter­na­tive sources of water as well as providing specialist prod­ucts for water supplies that may contain high levels of impu­ri­ties, nitrate, iron or heavy metals. What­ever the source or appli­ca­tion for your water talk to us to iden­tify the right water treat­ment solu­tion.

How does UV disinfection work?

UV Anlage desinfiziert Wasser
UV Anlage desinfiziert Wasser
The anti-bacterial effect of artificially generated UV radiation was discovered at the beginning of the 20th century. In 1902, for example, Austrian physician Gustav Kaiser reported successes with healing a wound that would not previously mend and healing a patient with tuberculosis. In the meantime, the disinfection of water using UV light has become a very common and reliable, method treating drinking water.

BWT's UV systems operate at a wavelength of 254 nanometres (nm). UV light with this wavelength has a particularly strong effect in destroying microorganisms. The DNA of the microorganisms is changed and they are no longer able to multiply. The centrepiece of BWT systems is one or more low-pressure lamps that produce UV light in the required intensity. The emitters are installed in a stainless steel chamber through which the water to be disinfected is passed. Thanks to UV radiation, existing germs and bacteria are reduced safely and, above all, without the addition of chemical substances.

Frequently asked questions about UV disinfection

Are water suppliers obliged to provide clean water?

Your water supplier is the guarantor that you get drinking water delivered to your home. The strict principles for this quality are laid down in the Drinking Water regulations. However, in your domestic water network this quality can be lost through heating, different materials etc. - problems such as limescale and corrosion can develop. The responsibility for the drinking water changes when it enters your home from the supplier to the house owner. Thus the "operator of a drinking water system" is responsible and influence the quality of the water at the tap.
