Does A Water Softener Remove Chlorine?

The presence of chlorine in our water supply is no secret. It is used to disinfect the water we drink, cook with, and use for other purposes. But when chlorine is present in our water it can cause a variety of unpleasant effects, from bad-tasting water to skin irritation.

So it’s no surprise that many people are wondering: Does a water softener remove chlorine? Water softeners do not remove chlorine from water. Although water softeners do not remove chlorine, they do offer other benefits to water. Chlorine is a chemical used to disinfect and treat water, and while water softeners can help improve the taste and smell of your water, they won’t remove chlorine.

However, research shows that there are other ways to remove chlorine and its by-products from water, such as using activated carbon filters, reverse osmosis systems, and ultraviolet purification.

What Is Chlorine? And Is It Dangerous?

Chlorine is an element that is found in nature, in the form of a gas and is essential for life on Earth. It is a powerful disinfectant and is used to sanitize drinking water and swimming pools, as well as in the manufacture of various products such as paper, plastics, and pharmaceuticals. In its elemental form, chlorine is highly dangerous, as it is a highly reactive gas that reacts with many other elements and can cause severe health problems when inhaled. 

Inhaling chlorine gas can cause respiratory irritation and difficulty breathing, as well as permanent lung damage. In high concentrations, it can also cause death. In accordance with the Centers for Disease Control and Prevention (CDC), a concentration of 1 part per million of chlorine gas is hazardous to human health, while a concentration of 0.5 parts per million can cause irritation of the eyes, throat, and nose. A concentration of 5 parts per million is considered immediately dangerous to life and health and can cause death within minutes of inhalation. 

Besides contributing to air pollution, chlorine also contributes to smog. According to a study by the Environmental Protection Agency (EPA), chlorine is one of the most abundant pollutants in the atmosphere and is second only to carbon dioxide as the most prevalent air pollutant. In the United States alone, over 12 million tons of chlorine are released into the atmosphere every year from industrial sources and the burning of fossil fuels.

It is important to be aware of the health effects of chlorine and to take the necessary precautions when handling it. Always wear protective gear such as gloves, goggles, and a mask when working with chlorine, and make sure to keep the area well-ventilated. When using chlorine-based products, follow the manufacturer’s instructions.

Does A Water Softener Remove Chlorine?

A water softener is a type of water treatment system that is designed to reduce the hardness of the water. It does this by exchanging ions with other substances, such as sodium or potassium, to replace the hard minerals in the water. While it can remove some of the harmful chemicals in water, such as lead and nitrates, a water softener cannot remove chlorine from water.

Chlorine is added to water supplies to kill bacteria and other microorganisms that can cause disease. Unfortunately, chlorine is difficult to remove from water, because it binds to particles in the water, making it difficult to filter out. The only way to effectively remove chlorine from water is by using a special carbon filter.

However, a water softener cannot remove chlorine from water. Chlorine is an oxidant and is added to municipal water supplies to kill harmful bacteria and other microorganisms. Softeners use a process called ion exchange which replaces the calcium and magnesium present in hard water, with sodium or potassium. This process does not remove the chlorine present in the water, since chlorine is not an ion.

This is because chlorine is a gas, and water softeners are not equipped to remove gasses from water. Chlorine is a chemical element and is not susceptible to the ion exchange process. These molecules are too small to be removed from water by a water softener. Additionally, the water softening process does not remove any other contaminant from the water. 

As mentioned earlier,  Water softening works by passing hard water through a bed of resin beads, which are charged with sodium ions. The result is soft water that has a higher concentration of sodium, which is safe to drink to some extent. 

The process of removing chlorine from water is called dechlorination and is typically done using specialized filtration or reverse osmosis systems. According to the U.S. Environmental Protection Agency (EPA), on average, public water systems contain roughly 4 parts per million (ppm) of chlorine

Water systems that use chloramine (chlorine and ammonia) rather than chlorine typically contain 2-4 ppm of chlorine. It is important to note that high levels of chlorine can be harmful to human health, so it is important to make sure that the water is safe for drinking.

Because water softeners do not remove chlorine, an additional water filtration system must be used to remove chlorine and other contaminants from water. According to the United States Environmental Protection Agency, using an activated carbon filter is one of the most effective methods for removing chlorine from drinking water. Activated carbon filters can reduce chlorine levels by up to 99%, depending on the filter’s capacity and the amount of chlorine in the water.

Why Remove Chlorine From Water In The First Place?

One of the main reasons to remove chlorine from water is because it can cause a variety of health issues. Chlorine is a strong oxidizing and bleaching agent and can irritate the eyes, skin, and throat when ingested in large amounts. Long-term exposure to chlorine has been linked to an increased risk of developing cancer and other respiratory illnesses, including asthma and bronchitis.

It can cause dry skin, eczema, and rashes addition, chlorine can damage the hair and skin, leaving it dry, brittle, and discolored. Removing chlorine from water can help reduce these risks and improve the overall quality and taste of the water.

Different Methods To Remove Chlorine From Water:

1. Activated carbon filters

One of the most effective methods to remove chlorine from water is to use activated carbon filters. These filters are designed to remove various contaminants from water by using activated carbon, a porous material that binds and traps chlorine molecules. The filters can be installed in home water systems or even as a standalone filter. For best results, the carbon filter should be replaced at least once a year.

2. Reverse osmosis 

Reverse osmosis is another option for removing chlorine from water. This process involves forcing water through a semi-permeable membrane that traps chlorine molecules, leaving clean, chlorine-free water on the other side. Reverse osmosis systems are very effective at removing chlorine, but they can be expensive and require a lot of maintenance.

3. Distillation

The last common method for removing chlorine from water is distillation. This involves boiling the water and trapping the vapor on a cold surface, which condenses the vapor back into liquid form. The condensed liquid is then collected, leaving behind the chlorine molecules. Distillation is a very effective method of chlorine removal, but it is also energy-intensive and can be expensive.

FAQs

What Happens To Chlorine In A Water Softener?

Chlorine is not affected by a water softener. It is removed from the water during a separate process known as dechlorination. In the dechlorination process, chlorine is neutralized with a chemical such as sodium thiosulfate. This reaction causes the chlorine molecules to break apart into chloride ions. The chloride ions are then removed from the water, leaving it safe for consumption.

Does Soft Water Have Chlorine?

Soft water typically does not contain chlorine unless it has been specifically treated with a softening system that adds chlorine.

Do Water Softeners Add Chlorine To Water?

No, water softeners do not add chlorine to the water. Water softeners work by exchanging salts in the water for calcium and magnesium ions, which are responsible for water hardness.

What chemicals does a water softener remove?

A water softener typically removes calcium, magnesium, iron, and manganese ions from the water, which is replaced with sodium ions. It may also remove certain forms of sediment and other organic compounds.

Verdict

Based on the evidence, it is clear that a water softener does not remove chlorine from water. While it can reduce some of the hardness and other minerals, it does not remove chlorine or the various chemicals that may be present in the water. 

Therefore, installing a water softener is not a viable solution for removing chlorine from water. While there are many other ways that can be used to remove chlorine from the water such as dechlorination, osmosis, distillation, etc.
