The Davey Steriflodomestic UV water disinfection systems are an effective and economical means of eliminating harmful bacteria from drinking water supplies. They can also be used for small scale waste water disinfection at reduced flow rates. Because these water disinfection systems use no chemicals, there is no unpleasant taste associated with their use. It is impossible to overdose, using this system.
UV light at the wavelength generated by the lamp in a Davey Steriflounit (254nm) is lethal to most micro-organisms as it damages their ability to reproduce. This type of UV water disinfection system is commonly used for water disinfection on a wide range of water sources by many local councils, the food, dairy and brewing industries and by thousands of private consumers to ensure their water is safe to drink.
An organism that has been subjected to UV light is no longer viable as it cannot grow to cause infection or be counted on a culture plate. It has been shown that cysts such as Giardia and Cryptosporidium are inactivated by UV but the water has to be very clean and free of particulate matter. Therefore filtration is part of all cyst control recommendations from Davey.
