Will a Water Softener Remove Chlorine? The Short Answer: No, But…
The simple answer is no, a standard water softener will not remove chlorine from your water. Water softeners primarily target hard water minerals like calcium and magnesium, using ion exchange to replace them with sodium or potassium. Chlorine, however, is a dissolved gas, not a mineral, and the softening process doesn't affect it.
However, the "but" is important. While a water softener doesn't directly remove chlorine, the process can indirectly impact its levels to a small degree. Let's explore this in more detail.
How Water Softeners Work (and Why They Don't Remove Chlorine)
Water softeners work by using resin beads coated with sodium or potassium ions. As hard water flows through the resin bed, the calcium and magnesium ions in the water bind to the resin, releasing sodium or potassium ions into the water in their place. This is ion exchange. Chlorine, being a dissolved gas, doesn't participate in this ion exchange process. It simply passes through the resin bed largely unaffected.
What About Other Methods for Chlorine Removal?
So, if a water softener won't remove chlorine, what will? Several options exist for chlorine removal, including:
-
Activated Carbon Filters: These are highly effective at removing chlorine and other volatile organic compounds (VOCs) from water. They work by adsorption, trapping chlorine molecules on the surface of the carbon. These filters are a common and relatively inexpensive solution.
-
Reverse Osmosis (RO) Systems: RO systems use a semi-permeable membrane to filter out a wide range of contaminants, including chlorine. These systems are more expensive than carbon filters, but offer more comprehensive water purification.
-
Distillation: This method boils water and collects the condensed steam, leaving behind impurities like chlorine. While effective, it's less commonly used for home water treatment due to its energy consumption.
-
Water Treatment Chemicals: Certain chemicals can be added to water to neutralize chlorine. This is typically not a practical DIY solution and is best left to professionals for water treatment facilities.
Will a Water Softener Reduce Chlorine Smell or Taste?
While a water softener won't remove chlorine, the process of softening can sometimes reduce the noticeable chlorine taste and smell. This is because the softening process alters the water's overall mineral content, which can subtly affect the perception of other substances like chlorine. However, this effect is usually minimal and shouldn't be relied upon as a primary means of chlorine removal.
Is Chlorine Removal Necessary?
The need for chlorine removal depends on several factors, including your water source, personal preferences, and health concerns. Some people are sensitive to the taste and smell of chlorine, while others may have concerns about potential health impacts of long-term chlorine exposure. If you're concerned about chlorine levels in your water, it's best to have your water tested by a qualified professional.
Can I Combine a Water Softener and a Chlorine Filter?
Absolutely! Many homeowners use both a water softener and a separate activated carbon filter to address both hard water and chlorine issues. The typical setup involves installing the carbon filter after the water softener. This way, the softened water is then treated to remove the chlorine.
This comprehensive approach allows you to enjoy the benefits of soft water without the unpleasant taste or odor of chlorine. It's always best to consult with a water treatment professional to determine the best system for your specific needs and water quality.
