Re: [Killietalk] Chlorine and Chloramine.
On Chlorine and Chloramine in RO waste water ...
Here is what I found with my testing. I repeated ALL tests three times.
Chlorine test kit is HACH. Ammonia tests where performed with both Aquarium
Pharm and Seachem kits. The Seachem kit is for reading ultra low amounts of
Ammonia and will register down to .1 ppm
Waste water from Kent RO unit tested 2.2 ppm Chlorine and 0.5 ppm Ammonia. I
then added pure thio solution obtained from LFS. LFS claimed that this was just
Thiosulfate in dH20. I needed to use double the amount suggested to get
Chlorine to 0. When Chlorine was at 0, Ammonia tested 2.0 ppm.
Water that sat for 48 hours with no Charcoal filter 0.0 ppm Chlorine, 0.0 ppm
Ammonia.
Water that sat for 48 hours with Charcoal filtering, naturally, was the same as
above for Chlorine and Ammonia, i.e. 0 for each.
I am very happy about this. It means that I can have pure 8 dH water with
storage and simple Charcoal filtration. I will continue the Charcoal because
of organics present in the water here, but simple Charcoal filtration will not
contain any Thio products which are not helpful to good microbe amounts.
However, as I read the results, it indicates that the old rule of Chloramine
not dissipating upon storage is not quite correct, at least at low amounts.
