What is your preferred method for removing chlorine or chloramine in tap water?

Thanks. The ascorbic acid vitamin c powder was recommended to me on a few different websites and forums. It looks like people that do home brewing like beer may use it to remove chloramine. I was told like 1/4 teaspoon or 1 gram would likely remove chloramine in 40 gallons of water. The reviews on amazon for the ascorbic acid powder I plan to use also mention using it to remove chloramine. It looks like people also use it in bath water on there.

OK, someone clue me in on why its dangerous to have a bath in water with any type of chlor in it? Yes the pure chlorine gas is toxic, but I've yet to hear of anyone being poisoned by chlorine gas from sitting in a steamy bathroom. Its all starting to sound tin foily to me. I think this lock down is getting to some people. Personally I've been living in lock down for the last 17 year anyway. I'm used to it, apart from unemployed nightclub bouncers now taking supermarket security guard jobs, which did cause an argument yesterday. I expect manners not orders barked at me by those whose jobs depend on peoples custom.

Thanks. I think a 1/4 teaspoon is like 1 gram right? If 1/4 teaspoon would do 40 gallons then if I only want to do like 4 gallons then 1/10 of 1/4 teaspoon would likely work for that right? I plan to use a 1/4 teaspoon to measure in and only fill it up like 1/4 or 1/2 of the 1/4 teaspoon. I got like 500g for around like $20 which if the numbers I read online are right then that would do like 20000 gallons for it on there.

I just throw in some dirt. A small handful of dirt in the 5 gal gives the chlorine/chloramine something to react to. I have noticed that the smell disappears almost instantly.

But where does the chlorine go? Humic acid is converted to chloroform by chloramine. Even so, similar organic reactions of chlorinated water is the excuse for why water treatment is moving towards chloramine.
Everyone knows that chlorine has no smell right?

Dilute some bleach with distilled water and neutralize it with pH down acid to pool pH of 7.5 and tell us again. It's true that many strange and sometimes odorous things can be formed from oxidation of organics by hypochlorite + hypochlorous acid (it's a 50/50 mix at pH 7.5), including chloramine from urine.

To properly remove them you will need to pass it through a carbon filter (carbon all around rules!)

I could have written your post except for that, since I have doubts about standard carbon filters with chloramine, except special expensive carbon. Ordinary activated carbon is better at removing free chlorine.

Ozone partially converts free chlorine to herbicidal ClO3-, but only gives NO3- and Cl- with chloramine.

Chlorine is a disinfectant! You figure it out from here. OTOH I will use evaporated H2O over RO any day of the week and twice on Sunday!

So is anti bacterial handwash. Not too dangerous though. Unless youre dumb enough to drink it. How many hospitalisations have you heard of from exposure to tap water due to the chlorine content? I have figured it out. Its not dangerous.

The issue is not what the chlorine does to you, it's what it does to the water first, and what that then does to you. This has been known worldwide since the 80's. Water filters are really popular since then for some reason. Have you noticed that for almost as long now bottled water is so popular it's sold from vending machines at ridiculous prices for water? Even though it's just chlorinated tap water from somewhere else. Chloramine is also not supposed to be good with lead pipes or really any plumbing parts, so naturally everyone is switching to it.

Look, I'm not a chemist. What does it do to the water first that is so bad for people? Other than saying its bad, can someone post why?

Don't try to be a smart arse Joe. Talking about bleach and chloramine doesn't start to answer the question. Nor does it prove anything about the absence of odor from pure chlorine gas. Chlorine has no smell, what ever bleach smells of. Still no word about how chlorine alters the properties of the h2o molecule either. Just a bunch of irrelevant nonsense. Sounds to me like you want to sound like an expert without actually knowing much.

Edit. OK the link was interesting, links between chlorine and bowel cancer. I hadn't heard of that tiny risk factor. Nothing to suggest it changes the properties of water itself though.

Are they not the subject of the thread?

What else would an odor threshold of less than half a ppm mean? Can you get any hydrochloric acid and potassium permanganate or manganese dioxide (from batteries if necessary)?

Still no word about how chlorine alters the properties of the h2o molecule either.
It doesn't, beyond forming hypochlorous acid or hypochlorite (mainly, chlorine hydrate or chloride and chlorate are possible). By water I obviously mean water as it comes out of your faucet, which is more than water.

Just a bunch of irrelevant nonsense.

Also known as facts. What, exactly, have I posted that is irrelevant to tap water chemistry?

Brilliant. Well done. You're obviously quite the gentleman and scholar just as surely as I'm a troll who knows nothing about chemistry. The first two words at the link: bladder cancer.

This is what I asked to be explained. Now the answer is, well nothing but but it er reacts with other stuff to er moving on.

Yeah yeah I converted bladder to bowel, its all human waste and the odds are still miniscule.


Have you ever worked with industrial chlorine gas? I'm guessing not. The Petro chemical industry does. In particular when adding lead to petrol. In domestic gas they add the smell for safety sake. Perhaps for domestic use something similar happens with chlorine? I don't know, my only experience is from industry, where chlorine has no odor.
I'm not getting into a pissing match with you about who's the brightest, you sound dehydrated, it wouldn't be fair.

This makes no sense, and the only place chlorine should be involved in leaded gas is in making the lead scavenger dichloroethane. My experience with chlorine is only from making it myself by the methods mentioned earlier and also from MnO2 with salt and sulfuric acid, potassium dichromate with HCl, and calcium hypochlorite added to a large excess of HCl or sulfuric acid.

I grow in dirt, so I use tap water without any additives, and it works a charm for me. As log as youn grow in dirt/soil the dirt will filter it for you

And I grow five to six crops a year, and they average about a gram/watt so I'm happy with that (and so should you)
