Chlorine and chloramine are used to treat tap water. While this practice is necessary to ensure our safety, it leaves water with an unpleasant taste and odor. There are also several health risks associated with high levels of chlorine in the water we use for drinking and cooking.
Given that chlorine is not the best for drinking water; the question many are asking is how to remove chlorine from water?
In the early 20th century, scientists discovered that small amounts of chlorine will kill most bacteria and pathogens in water. At the time, diseases like cholera were a plague in cities around the world. Chlorine was seen as an obvious solution to a real problem.
Later, chloramine was substituted for regular chlorine by some water supply utilities. This is a combination of ammonia and free chlorine. The benefit of using chloramine vs chlorine is an improved taste and odor. However, the health implications of chloramide are similar to chlorine.
In many cases, excessive amounts of chlorine are used to sanitize municipal water. We can smell it the moment we open a faucet. For certain health conditions this can have a negative effect.
The recommended dosage for water treatment is 5mg of chlorine per liter. For long distance supply, water treatment facilities may choose to increase the amount of chlorine used.
Why Should you Remove Chlorine from Water?
While chlorinated water, if correctly monitored, is generally safe for human consumption, there are good reasons to remove chlorine from our water before using it.
If you allow water to stand for about 30-minutes, the chlorine will dissipate into the atmosphere. However, this is not the case for chloramide. Even though the water may no longer smell or taste of chlorine, VOCs will still remain in the water after standing.
Boiling water will remove chlorine and kill bacteria, as well as most organic compounds.
A water filter is generally accepted as the most convenient and safest method of removing chlorine from water. Filters, like reverse osmosis, activated carbon, and ultraviolet light will not only remove chlorine, but many other contaminants.
A relatively cheap and easy method of safely removing chlorine from the water we use for drinking and cooking is a water filter pitcher. These filters use activated carbon to remove contaminants, like chlorine from the water.
Water filter pitchers are inexpensive, and the filters are easily replaced. Using the pitcher is a simple matter of filling the reservoir from a faucet and allowing it to stand while the water flows through the filter.
The filter will remove chlorine. It may also remove harmful metals, organic compounds, and other elements that affect the taste and health of the water we drink. While most filters remove chlorine, the benefits will vary depending on the type of filer media that is used.
Before buying a water filtration system for your home, it would be a good idea to consider your options. Read reviews and compare products to ensure you’re getting what you need.
While water filter pitchers are probably the most popular, and generally the cheapest way to remove chlorine from water. They have their drawbacks. Limited capacity means that filtered water storage is typically less than a gallon.
For large water consumption, pitchers can be wholly unpractical. The small filters used for pitchers do not last very long and need to be replaced more frequently than larger filters. This can become expensive, especially for large families and for use in offices where you require more filtered water.
There are many benefits to removing chlorine from your water. Apart from improved taste and smell, the water you drink will be healthier. It is also better for your pets.
As a result, water filters have become increasingly popular. They not only remove chlorine but serve as a multi-purpose water purification system.
The type of water filtration system you choose will be based on your requirements and budget. Here’s a summary of the common water filtrations systems used to remove chlorine:
