Due to the growth of technology, many have focused on ways to rid their drinking water of chlorine. The following paper will discuss in depth if water filters exist that remove chlorine, different ways of filtration, their effectiveness, and how a suitable system can be chosen for the removal of chlorine.
1. Understanding Chlorine in Water
What is Chlorine and Why is it Used in Water Treatment?
Chlorine is a strong disinfectant applied to treat water throughout the treatment process. It primarily kills bacteria, viruses, and other microorganisms that can cause waterborne diseases. A residual amount of chlorine in a municipal water distribution system will ensure the water does not get contaminated before it flows out of consumers’ faucets.
Health Effects of Chlorine Consumption
Although chlorine can effectively eliminate hazardous pathogens, its consumption in large amounts is likely to cause adverse health effects. Exposure to high volumes of chlorine has been reported to cause respiratory problems, skin irritation, and gastrointestinal problems. Furthermore, chlorine may combine with organic matter present in water to create DBPs such as trihalomethanes and haloacetic acids. These are reported to increase the chances of cancer and other health problems.
Taste and Odor Issues Due to Chlorine
Beyond health considerations, chlorine can much more strongly affect the sensory qualities of water. At even relatively low concentrations, the chemical taste and smell of chlorine are unmistakable and unpleasant for many. This could finally result in preventing people from drinking enough water and impeding overall health and hydration.
2. Reasons to Filter Chlorine in Drinking Water
Health Reasons
The filtration of chlorine from drinking water minimizes your exposure to the harmful byproducts of disinfectants. By lessening the amounts of chlorine in the water, there is lessened risk for health issues related to this chemical and better well-being in the future.
Taste and Smell
Extraction of chlorine enhances the taste and smell of water and, therefore, it becomes more palatable, with an increasing quantity of it being consumed. This is useful for households where the taste of tap water is considered unattractive, and that condition hampers the proper hydration of family members.
Protection of Plumbing and Appliances
Chlorine is corrosive and can do harm to the plumbing materials as the time goes on. What’s more, a high chlorine level may degrade the pipes, faucets and other appliances, which will increase the unexpected maintaining cost. In this circumstance, the filtration of chlorine may do you a favor to protect the plumbing systems as well as enhance the durability of your household appliances.
