UV light at the wavelength generated by the lamp in a Davey Steriflo unit (254nm) is lethal to most micro-organisms as it damages their ability to reproduce. The organism is then no longer viable as it cannot grow to cause infection or be counted on a culture.
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.

The design of the the treatment chambers are 304 stainless steel for cleanliness and long life.
The Davey Steriflo system is designed for continuous operation treating cold water (up to45⁰C) at any flow from zero up to the design flow rate.
Extended periods of zero flow are not harmful as long as the treatment chamber is full of water.
The Davey Steriflo range is suitable for potable water and food industry use.
All wetted components are USDA listed.
Lamps are single ended for ease of servicing and connection.
Disassembly for cleaning of the quartz sleeve is quick and user friendly with positive sealing at both ends.  

      NOTE

• Pre-treatment (drinking water) Prefiltration is advised to ensure that particulate matter does not shield micro-organisms from the UV light.
