Chloramine is formed when chlorine atoms bond with ammonia atoms. The chemical formula of chloramine is (NH2Cl).I wrote this post on how to remove chloramine from tap water because like many people I had no idea what is chloramine.
Chlorine has a long history of being used as a disinfectant. The first place to adopt chlorine in to treat used in Louisville, Kentucky in 1908. Chlorination is a simple and effective method of fighting water born diseases like chlorella and decently.
The decline of deaths associated with water born illness in the world can be attributed to the adoption of chlorination to treat water in many cities around the globe.
In recent years many cities are moving away from using chlorine and adopting chloramine as a disinfectant. Chloramine is used instead of chlorine because it is more stable and doesn’t deplete as quickly as chlorine
Chloramine used in low concentration by municipality water distribution department as a disinfectant. Many Environmental protection agencies encourage cities to adapt chloramine as a disinfectant.
In some cases, it is absolutely necessary to remove chloramine from water. Chloramine should not be present in water used for kidney dialysis water. Also, when it comes to homebrewing, chloramine affects the quality of beer brewed because of its test
Facts about chloramine
It is a well-known fact that chloramine typically evaporates when it exposed to the atmosphere. It takes up to 24 hours for chloramine to evaporate. On the other hand, free chlorine takes only four hours to turn into gas and dissolve into the atmosphere.
When you shower with water that contains chloramine, it erodes the oil layer found naturally on the surface of the skin, and it leaves your skin feeling dry. Showering with water that contains chloramine can cause hair loss.
What are the different ways chloramines can find its self inside the body?
Chloramine can get inside the body through two main ways. One is through drinking tap water and showering with chloramine-treated water. According to research, we absorb more chloramine through the skin than by drinking.
What are the effects of chloramine on fish:
For a fish tank, You should not use water that has chloramine because it poisons and kills the fish very quickly.
Chloramine also kills bio bacteria which are necessary for fish to survive.
How to remove chloramine from tap water
The first step is to separate it into chlorine and ammonia. Then
Chlorine is removed using one process and ammonia is removed using a separate process.
For people with healthy liver, this might not be a big concern because the liver can convert it into urea which eliminated through urine.
- Ascorbic acid (Vitamin C)
- Passing ultraviolet light
- Boiling tap water
- Catalytic carbon filters
- Adding reducing agents such as Campden tablet
- Installing reverse osmosis
Filtering chloramine using ultraviolet light
Beverage companies have been using this method to remove chloramine and chlorine for a long time, and it is an accepted method of neutralizing chloramine and chlorine.
Vitamin C, also known as Ascorbic acid, is good at removing chloramine and chlorine from water.
Filtering chloramine using Catalytic carbon
Carbon whose surface has been modified to make by going through a chemical process is called Catalytic carbon.
Catalytic carbon-based filters can neutralize chloramine from water.
Homebrewers use reducing agents such as potassium metabisulfite to remove both chloramine and chlorine from water.
Another effective method of removing chloramine is by use of reverse osmosis.
I have found that for tap water the best method of removing chlorine from water is by use of under the sink filters. These under the sink filters can remove chloramine and chlorine efficiently. Some of the under the sink filters use activated carbon and other use reverse osmosis.
Activated carbon under sink filters.
These filters use replaceable cartridges to filter out chloramine and chlorine from the water. Activated-carbon under the sink filters process water on demand do not need a storage tank.
Reverse osmosis under sink system
Reverse osmosis uses a semi-permeable membrane to remove chemicals and unwanted material from water to make it safe for human consumption. These types of filters remove chlorine, chloramine, nitrate, fluoride and other chemicals from water. Reverse osmosis under sink systems is an effective method of removing chloramine from water although it is a bit expensive.
How to remove chlorine and chloramine from water for home brewing purposes
For homebrewers, the quality of water is essential because it affects the test of the final product. A simple solution for removing chloramine and chlorine is to add Campden tablets (potassium metabisulfite).
Although chloramine helps to kill germs in the drinking water, it is harmful when we drink it. Therefore, You should remove chloramine from water especially if the water is for the fish tank or kidney dialysis. There many ways of filtering chlorine and chloramine from tap water The use of under sink water filter is practical and straightforward. Besides, it is workable and does a good job. You can choose between reverse osmosis or activated carbon.
