Steriflo Water Treatment Systems


Ultra violet water treatment system for inactivation of virus and bacteria in drinking water. Steriflo is ideal for treating rainwater for drinking.


UV 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.
UV light at the wavelength generated by the lamp in this 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
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. 

The  system is designed for
continuous operation treating cold water
(up to 45oC) 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. Allow
2 minutes warm up from switching on
before starting flow. Allow 24 hours
operation for a new lamp to develop full
output.




The Davey Steriflo® domestic 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. • No chemicals • No taste • Impossible to overdose
UV 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. 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 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.
 





The design of the Davey Steriflo® range of UV sterilisers is intended to provide many years of reliable operation at an economical price.
The design of the the treatment chambers are 304 stainless steel for cleanliness and long life.

Extended periods of zero flow are not harmful as long as the treatment chamber is full of water. Allow 2 minutes warm up from switching on before starting flow.

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.
Pre-treatment (drinking water) Prefiltration is usually to ensure that particulate matter does not shield micro-organisms from the UV light. Depth sand filtration or 20 micron cartridge filtration is the usual minimum. In some cases, particularly with surface water, finer filtration may be necessary, or if cysts like Giardia or Cryptosporidium may be present. In this case 1 micron filtration is required, not necessarily for the whole supply, filtration for the drinking tap only may be practical.
The power supply should be mounted in a dry location. 1 metre of lead to the lamp is provided. Installation can be horizontal or vertical and piping should be arranged so that the unit stays full of water. If horizontal, the inlet and outlet should point upwards, if vertical the inlet should be at the bottom. Mounting brackets are provided for easy installation. All units are supplied with full installation and operating instructions to ensure proper usage and assist with long term maintenance. Warning: UV light is harmful to eyes and exposed skin. A safety notice is included with the operating instructions. NEVER LOOK AT A UV LAMP WHEN IT IS SWITCHED ON.
