Creating Clean Water: UV Filters

I mentioned in the previous post that we draw our water from the Lake rather than a well. This presents an additional risk from thing that grow in lakes - in particular I was concerned about bacteria and viruses including chlorine resistant cysts such as Cryptosporidium and Giardia - no beaver fever for me!.

After a bit of a Internet search I settled on the systems manufactured by Trojan, built right here in Canada. In particular I purchased the TrojanUVMax D4.

The folks at Trojan have a great selector tool for determining which of their models fit your specific needs.

The key features I appreciated are:

1) User Interface
  • Lamp timer display starts at 365 and counts down the days to annual lamp replacement
  • Mute button allows you to silence an alarm
2) Lamp/Sleeve Combination
  • Lamp and sleeve are removed without the use of any tools
  • Lamp and sleeve remove from the UV chamber as one piece ensuring you are aware of any build up of minerals on the sleeve that may interfere with the proper UV dose being delivered to the water
3) Advanced Lamp Technology
  • Low pressure high-output lamp technology provides higher UV output for better water purification in a system approximately half the size of conventional systems - saving space and making installation simpler
4) Constant Current Electronic Power Supply
  • More energy efficient
  • Withstands fluctuations in voltage that can cause low UV output and damage to the lamp
5) Safety Cap & Special Lamp Plug
  • Safety cap prevents children from accessing the lamp or electrical components. It also prevents the lamp plug from accidentally being disconnected. Lamp plug design ensures that no one can power the UV lamp if it's not in the UV chamber. This prevents damage to eyes and skin from UV light.
