Thanks for the comment Ian,

The filter hasn't performed as well as required tbh. Our filter changing regime is once a month and this experiment has shown that the filter alone has only lasted around two and a half weeks of a thrice weekly dialysis program.

From a safety point of view the patient is still being exposed to chlorine levels well below the allowed limits - phew!  
Should the RO be considered part of the chlorine removing setup?  I think not but it can provide the redundancy that you mention I suppose!?

I think I am going to continue the experiment with the current filter to see how the exhaustion pans out and see just how far we can push it before a patient risks exposure with the protection of the RO.  I think it would be interesting to connect the RO straight to tap water and see what results it brings.

I have a carbon block filter standing by for stage 2 so we'll hopefully see a dramatic improvement.

If anyone out there knows how to calculate the approximate contact time using a cartridge filter and the flows I've been tabulating I think it would be interesting to see what it is.
