There are several ways of de-chlorinating water to free it from the unpleasant smell and an awful taste.  In most cases, chlorine is essential for the eradication of disease-causing microorganisms and the prevention of diseases like cholera.

Some industrial uses do not go well with chlorinated water, and definitely aquatic animals do not survive in chlorine-treated water. It has a very high acidic level that makes it unsuitable for the habitats on fish and scientific processes. In this article, we will look at various methods on how to remove chlorine from water. Let’s see.

The Most Applicable Methods on How to Remove Chlorine from Water

These are some of the most applied methods in which you can free your water from chlorine if you want to keep an aquarium or have odorless, clean water. Some of them are DIY methods that are convenient and cheap to use at home are listed below. They include:

How To Remove Chlorine From Water

1- Use of a Filter

Prepare the filtration site by using thin granules of sand or pieces of charcoal that is a sound absorbent. Ensure that the parts of the charcoal are fine in texture so that it can be a good adsorbent surface. Pass the water through the surface, and chlorine ions will react with carbon in the charcoal.

Get the filtrate as the chlorine-free water and the residue as the carbon-chlorine bond. Eradicate the materials used to prepare a new surface that will be used for the remaining water. The whole process must have a flowing water so that the surface will be efficient. A charcoal surface is preferred to the sand or other materials because it does not leave any odor or dirtiness in the filtered water.

You can use a more advanced method by involving the conversion of liquid chlorine to chloride ions and passing through charcoal where it’s absorbed. The conversion is aided by a complex of chlorine soluble metals that can react with chlorine by absorption. This method is also referred to as reverse osmosis, and it’s instrumental in trapping not only chlorine but also organic compounds.

2- Through Neutralization Chemicals

Before choosing the chemicals used to neutralize chlorine, you must understand what the resultant water will be used for. Some substances are poisonous for human consumption, and it’s not advisable to de-chlorinate water without asking for the side effects. Some of these neutralization chemicals with sulfur-containing compounds will be very harmful to usage.

Consider natural chemicals like ascorbic acids that will be edible and hence appropriate for human consumption. It’s prohibited to drain water into the rivers because it will harm the aquatic life. The addition of neutralization chemicals will eradicate the chlorine because of the formation of a salt and water.

The chlorine will form a spice that can be filtered off as a residue. It is only efficient for human consumption when you use the edible salts other than these poisonous ones.

3- Eradication of Chlorine through Evaporation             

This is one of the most convenient ways to get rid of chlorine in water by exposing it to heat so that it evaporates. Chlorine is very volatile at room temperature, and an application of some heat will escape from the surface of the water. You can accelerate the process by increasing the temperature or boiling the water.

Significant exposure of the water to the atmosphere will increase the chances of chlorine escaping. Still, if it has chloramines that do not decompose quickly on air, the process becomes complicated. It does not apply to most large scale firms that might find the process involving and time-consuming.

If the only alternative is to use water-free form chlorine, then you should avoid industries that have chloramines in their systems so that you can protect your aquariums. Chlorine is poisonous to the fish and can retain their growth, making it difficult for their survival. Next time when you are changing the aquarium’s water, you will need to consider alternative ways to get rid of the water with chloramines.

The Bottom Line

The above methods of removing chlorine from water are used on a domestic basis because they can be effectively applied to small amounts of water. Evaporating the water to get rid of chlorine is cheaper than the other method because all you need is heat. Filtration requires continuous replacement of the adsorbent water, which is costly to keep up with.

However, filtration is the most effective because it removes not only chlorine but also its compounds. There are stable compounds of chlorine that cannot decompose under low temperatures.
