Will a Water Softener Remove Chlorine? The Surprising Answer
Many homeowners invest in water softeners to tackle hard water issues, but a common question arises: will a water softener remove chlorine? The short answer is: not effectively. While a water softener might slightly reduce chlorine levels, it's not its primary function, and it won't eliminate the chlorine from your water significantly. Let's delve into the specifics.
How Does a Water Softener Work?
To understand why water softeners aren't effective chlorine removers, we first need to understand their mechanism. Water softeners primarily target hard water minerals, specifically calcium and magnesium ions. They use an ion exchange process, where these hard water ions are swapped for softer sodium ions. This process doesn't interact with chlorine in the same way.
What Removes Chlorine from Water?
Chlorine removal requires different methods. Several options effectively tackle this:
-
Activated Carbon Filtration: This is the most common and effective method for removing chlorine from water. Activated carbon filters absorb chlorine molecules, effectively reducing or eliminating their presence. These filters are often integrated into whole-house filtration systems or used as standalone countertop filters.
-
Reverse Osmosis (RO): RO systems use a semi-permeable membrane to filter out impurities, including chlorine. This is a highly effective method, but it can be more expensive to install and maintain than carbon filters.
-
UV Sterilization: Ultraviolet (UV) light can kill bacteria and viruses, but it doesn't remove chlorine directly. It's often used in conjunction with other filtration methods.
Why Doesn't a Water Softener Remove Chlorine Effectively?
The ion exchange process in water softeners doesn't interact with chlorine molecules. Chlorine is a dissolved gas, not an ion like calcium or magnesium. Therefore, the resin beads in the softener don't have the capacity to attract and remove chlorine. Any slight reduction observed might be due to other factors, not the core softening process itself.
What About the Claim of Chlorine Reduction in Some Softener Systems?
Some water softener systems might advertise reduced chlorine levels. However, this is often due to the inclusion of additional filtration stages beyond the basic ion exchange process. These additional stages typically incorporate activated carbon filters or other chlorine-reducing mechanisms. So, the chlorine reduction is not a function of the water softening process itself.
Can I Use a Water Softener AND a Chlorine Filter?
Absolutely! Many homeowners use both a water softener and a separate chlorine filter. The water softener addresses the hardness issue, and the separate filter targets the chlorine. This provides comprehensive water treatment for various contaminants.
How Can I Tell if My Water Has Too Much Chlorine?
High chlorine levels can impact the taste and smell of your water, making it unpleasant to drink. Additionally, long-term exposure to high chlorine levels can have potential health effects. You can contact your local water utility for a water quality report, or you can have your water tested by a private lab.
In conclusion, while a water softener can improve water quality by reducing hardness, it won't effectively remove chlorine. To eliminate chlorine, you'll need a dedicated filtration system, typically using activated carbon filtration or reverse osmosis. Using both a water softener and a separate chlorine filter offers the most complete water treatment solution.
