Effective Ways to Neutralize Chlorine in Water

Chlorine is a chemical element belonging to the Halogen group, and it has widespread applications in various fields, serving useful purposes in our daily lives. However, the presence of excess chlorine in water can be a concern, and it is crucial to understand the proper and safe methods of chlorine-treated water production in chemistry, as well as the effective and timely techniques to handle the residual chlorine levels in water. This article will delve into the details of chlorine-treated water production and the efficient ways to  neutralize chlorine in water.

Producing Chlorinated Water

The process of producing chlorinated water is relatively straightforward, and it can be carried out by anyone with a few simple steps. To begin, one can simply allow the interaction between Cl and water, which will result in a pale yellow solution that can turn litmus paper from purple to red. This solution is the chlorinated water, but it will quickly lose its initial yellow color due to the highly oxidizing nature of HClO. The standard chemical equation for the production of standard chlorinated water is as follows:

Cl2 + H2O ==> HCl + HClO

Key Features of Chlorinated Water

Before learning how to neutralize chlorine , we need to understand the characteristics of liquefied chlorine gas, it is essential to explore the properties of this chemical in more detail.

Physical Properties

Chlorine is a nonmetallic element belonging to the Halogen group, existing as a gas under normal conditions. Chlorine is a dull yellow gas with a pungent odor and is approximately 2.5 times heavier than air, posing a toxic hazard to humans upon direct exposure. It is also soluble in water and readily dissolves in various organic solvents. In the natural environment, you can easily find chlorine in the form of chloride salts, such as sodium chloride (table salt), carnallite, and potassium chloride.

Chemical Properties

Regarding chemical properties, chlorine is an atom with an electronegativity of 1.6, ranking it just behind oxygen and fluorine. Due to this, chlorine has oxidation states of (+1), (+3), (+5), and (+7). In some special cases, chlorine can have an oxidation state of (-1), making its fundamental chemical property one of strong oxidation.

Disinfection Mechanism

As many people are aware, chlorinated water contains a type of oxidizing acid called HClO. However, the disinfection mechanism of chlorinated water is not solely due to HClO, but rather the oxygen atoms that are liberated from HClO. HClO is a weak acid, and it can easily dissociate at room temperature, forming HCl and [O]. The chemical equation for the decomposition of hypochlorous acid is as follows: 

HClO ==> HCl + [O]

Effective Ways to Neutralize Excess Chlorine in Water

Producing chlorinated water is straightforward, but effectively removing the excess chemical is not something everyone is familiar with. Recognizing the potential hazards of excess chlorine, we have compiled a list of useful information on efficiently  neutralize chlorine in water.

Using Ultraviolet (UV) Radiation to Remove Excess Chlorine

To  neutralize chlorine in water , an effective method that many people have successfully used is to expose the water to high-intensity UV radiation from a UV lamp. This process creates a wide spectrum of radiation that primarily reduces the free chlorine and chloramines by separating them into HCl (hydrochloric acid). However, this method requires considerable effort and is more suitable for industrial applications with modern and advanced lighting setups.

Using Chemicals to neutralize Chlorine

In addition to using UV radiation, customers can also consider using chemicals such as Chloramines and Metabisulfites to  neutralize chlorine . Since this is a method that involves the use of chemicals, users must strictly follow the instructions provided by the manufacturers. Additionally, this approach is more suitable for domestic water usage and should be limited for direct drinking water to avoid the risk of overdosing, which can have direct health implications.

Exposing Water to Open Air

The process of producing chlorinated water is quite simple, and the method of exposing the water to open, well-ventilated areas to allow the chlorine to evaporate is also relatively easy. Based on the properties of chlorine mentioned earlier, we know that this chemical exists in a gaseous state under normal conditions. Leveraging this characteristic, you can apply a rather manual approach by exposing the water to well-ventilated areas, allowing the chlorine to gradually evaporate. However, this method is only temporary and can only remove a certain amount of residual chlorine, not a large quantity.

Using Activated Carbon to neutralize Chlorine

The mechanism of using activated carbon to  neutralize chlorine in water is highly effective. The carbon in the activated carbon reacts with the chlorine and helps remove it from the water. According to previous calculations, 1 kg of activated carbon can help remove up to 6 kg of chlorine, which is a substantial amount. The best approach is to use an activated carbon filter, a specialized device designed to remove residual chlorine quickly and effectively.

Utilizing Reverse Osmosis (RO) Filtration

Surely, you are well aware of the health risks associated with using household water that contains chlorine levels exceeding the permissible limits. However, finding a fast, easy, and efficient way to  neutralize chlorine is not a straightforward task, and not everyone is familiar with the solutions. The introduction of RO water filtration systems has provided a viable solution. These systems operate on a closed-loop process and the principle of osmosis, enabling them to effectively filter out the excess chlorine from the water, as well as other harmful substances and sediments.
