No, I don't want to use an expensive or activated charcoal filter.
The local water is quite good but as the dam levels go down the chlorination seems to go up.
I have this half-baked theory that that chlorine is not good for my wonderful, probiotic 'wee beasties' that I cultivate. . . .
SO> > >
1 Will boiling water in an electric- or other- jug reduce/eliminate chlorine?
2 Will sitting a jug of water- with a wide open neck- for 12-24 hours in the frig., reduce chlorine levels in the water?

Tar muchly
Because you have been good, and read thus far, you can now get to look at this

Re: Getting clorine out of water

Leaving water out to "air out" will certainly reduce/eliminate chlorine levels. I let my plant water sit for 2 days before I water the plants. If I didn't own a water filter, I'd do the same for my drinking water.

For a more precise answer, we would need precise variables such as concentration (of chlorine), temperature, etc.

Re: Getting clorine out of water

Chlorine escapes water as a gas. That's why you have to keep adding chlorine to your swimming pool. The mere fact that you can smell it, points to chlorine escaping.

So, if you have enough time, just leave it standing for a while.

Exactly how long would depend on the chlorine levels in your water, the shape of the container you leave it standing in, how much water surface is exposed to air, actual airflow over the container, air temperature, water temperature, air pressure, etc.

So it would be a bit of a complicated calculation to make, but I'm pretty sure that if you can't smell the chlorine anymore, it would be fine.

Boiling it would also help, but that would remove a lot of oxygen out of the water, and that won't help your wee beasties one bit!

Re: Getting clorine out of water

We drink dechlorinated tap water at home. It tastes noticeably better than tap. We use activated charcoal and boiling where appropriate. If you boil, you're wasting electricity or fuel. Just keep this in mind. If you use activated charcoal, you're wasting money but maybe the charcoal can find a new life in the garden or potted plants at the end of its life. You'll also remove any dissolved minerals that might benefit plants or beasties.

For wee beasties or house plants, I leave the water for plants out for 1-2 days. Better if in that wide-necked container or jar you mentioned. Be aware that if chloramine is used instead of the usual chlorine, air exposure may not be enough to clean out the chlorine and make it "wee-beastie" friendly. Chloramine is supposed to be more stable.

How would you know. Ask your water provider (in my case the council)?
Should I use chloramine in my pool?

THANKS EVERYBODY

Check this out Mike. It seems that chloramine can be compromised by chlorination.

Re: Getting clorine out of water

got a vacuum pump? put your water in a sealed container and lower the pressure in that container.

Offhand chlorine boils around -34 C (~140 K) at ~101KPa
water boils around 100 C (~273 K) at ~101 KPa

SO if you reduce the ambient pressure in the bottle to a point just above one where the water itself boils at room temp, then you should quickly remove any Cl from the solution.

Hope it helps.
