Chloramine Wikipedia

[nfored]

Chloramine can be removed from tap water by treatment with superchlorination (10 ppm or more of free chlorine, such as from a dose of sodium hypochlorite bleach or pool sanitizer) while maintaining a pH of about 7 (such as from a dose of hydrochloric acid).

Hypochlorous acid from the free chlorine strips the ammonia from the chloramine, and the ammonia outgasses from the surface of the bulk water. This process takes about 24 hours for normal tap water concentrations of a few ppm of chloramine. Residual free chlorine can then be removed by exposure to bright sunlight for about 4 hours.

Is this saying I can fill a 100 gallon tank with water put a bubbler and a massive dose of pure chlorine, and in 28 hours have only H2O left.

More or less yes.

Depends on the pH.

Also your releasing chlorine gas so there goes the paint on the side of the house . Or the plants .

Is the method going to be cheaper than using dechlor? you'll have to price the chemicals in your area and see if you can get them in bulk vs dechlor in bulk.

Keep us updated on your findings.

As an added benefit the added use chlorine bleach (Sodium hypochlorite) will also remove any nitrite from tap water too.

Very interesting but, considering i changed my major from biology to business finance because of chemistry class I'll leave all this to you guys.

Here is a research hint: you just shocked a swimming pool.

Sodium hypochloride and calcium hypochloride will both jack the pH to deadly levels.

Chlorine gas (Cl2) will react with water producing 50% hypochlorous acid and 50% hydrochloric acid. It will lower the pH to deadly levels.

All forms of "free" chlorine react with water to form hypochlorous acid. This is the form of chlorine that is in tap water.

Lithium hypochloride is probably going to be the most promising souce of chlorine but it is by far not the cheapest.

Chloramines
Chloramines come in two forms, monochloramine and polychloramines. Monochloramine has a much higher oxidation reduction potential (ORP) than hypochlorous acid by itself. Polychloramines typically have so much organics in the molecule that they have very little oxidation reduction potential.

In swimming pools, monochloramines are formed by joining chlorine with cyanuric acid. In water treatment, it is by fixing it to ammonia. In the case of swimming pools, the breaking of the bond in monochloramines by shocking is actually an exchange reaction. This just means that when the bond is broken to release one chlorine atom, it is just long enough for another chlorine atom to replace it. I am not certain of the reaction of ammonia based monochloramines.

When gurus in the pool industry talk about break point shocking, they are talking about the 10ppm needed to break the polychloramine bond and to oxidize the organics in order to prevent them from reforming polychloramines. Shocking below the break point results in the reforming of polychloramines.

Chloramine can be removed from tap water by treatment with superchlorination (10 ppm or more of free chlorine, such as from a dose of sodium hypochlorite bleach or pool sanitizer) while maintaining a pH of about 7 (such as from a dose of hydrochloric acid).

Using hydrochloric acid (muriatic acid) is super tricky when you are working with small amounts of water. The pH game could be enough to pull the plug on the project.

Hypochlorous acid from the free chlorine strips the ammonia from the chloramine, and the ammonia outgasses from the surface of the bulk water. This process takes about 24 hours for normal tap water concentrations of a few ppm of chloramine. Residual free chlorine can then be removed by exposure to bright sunlight for about 4 hours.

If ammonia off gassed so easily, aquarium water quality would be a cinch.

Is this saying I can fill a 100 gallon tank with water put a bubbler and a massive dose of pure chlorine, and in 28 hours have only H2O left.

It's not going to be that easy. And no, it won't be pure water that is left. The carrier chemical of the chlorine source will remain after the chlorine is removed from the water.

Thanks Guys for the good info, I hate wasting time, so i will take your advice and just ignore this option.
