Can you boil away chlorine in water

In this brief guide, we will address the query, “Can you boil away chlorine in water?” We will also discuss why is chlorine added to water and does it affects human health, does boiling water removes chlorine, how much time it needs, and what are the advantages and disadvantages of boiling away chlorine in water

Can you boil away chlorine in water?

Yes, you can boil away chlorine in water by simply boiling it for 15 minutes. 

We know that chlorine is a gas, so logically it will evaporate naturally from liquid to the air, so  boiling the chlorinated water at a high temperature will only speed up the chlorine removal process.

However keep in mind that boiling is not a practical solution to dechlorinate large amounts of water, it is both costly and time-consuming, besides it will only remove free chlorine not that combined with other chemicals such as ammonia. 

Why is chlorine added to water?

Before we discuss how boiling water removes chlorine, we should initially share with you what are the reasons behind adding chlorine into the water in the first place and what is the benefit of doing so?

Water is an essential element for all living creatures, but unfortunately, it is not always safe to drink water directly without treatment due to its contamination with pollutants and the presence of pathogenic microorganisms that threaten human life.

For this reason, chlorine is used worldwide for being an incredible disinfectant of the water system. It is a cheap and effective way to disinfect water from all types of pathogens, bacteria, viruses, and other microorganisms that cause disease or mortality.

What is the impact of chlorine consumption on human health? 

Adding chlorine is considered one of the most cost-effective options used to treat and disinfect drinking water at a large scale from pathogenic microorganisms and other waterborne diseases such as cholera, typhoid, and dysentery.

However, even if the chlorine concentration used for water disinfection is considered safe and non-toxic to human beings and doesn’t have any serious negative consequences on health in the long term,  it can still have adverse harmful effects such as:

  • Dehydration caused by less drinking of water because of its unpleasant smell and taste
  • Gut problems due to the destruction of flora in your gut (probiotics or good bacteria)
  • Carcinogenic effect, increased risk of colonic tumour growth
  • Birth defects, heart and brain dysfunction in the foetus
  • Food allergy

How does boiling water remove chlorine?

Boiling water is considered to be one of the most popular basic methods used for water purification and removal of free chlorine. 

According to chemistry, chlorine is a gas and thus it is normally volatile at room temperature, however, chlorine’s evaporation rate will increase with temperature increase.

Therefore, when you boil chlorinated water heat will force dissolved gases such as free chlorine to leave the water into the air and diminish at the same time the water’s ability to hold gases. 

You should also keep in mind that the efficiency of boiling water in removing chlorine is highly influenced by the water’s surface area. In other words, large amounts of chlorine will evaporate by boiling a large pot of water compared to boiling water in a narrow pot.

What is the time required to boil chlorine in water?

It is estimated that the optimum boiling time that is sufficient to remove free chlorine from water ranges between 15 and 20 minutes. 

In other words, each 1 mg/L of free chlorine needs approximately 3.7 minutes to completely vaporise from 10 gallons of boiling water.

What are the advantages and disadvantages of boiling away chlorine in water?

Despite the widespread usage and good reputation of boiling away chlorine from water as being a fast and cheap method regarding the types of equipment needed. It is considered on the other hand costly and time-consuming.

Find below a table of comparison between the main advantages and disadvantages of the boiling method used to remove chlorine from water.
