Spring water filtration primarily involves removing impurities once the water reaches the bottling facility. The most common method is carbon filtration.
Carbon Filtration: The Primary Method
Once collected, spring water typically undergoes carbon filtration. This process aims to remove chlorine and other volatile organic compounds (VOCs) that may affect the taste and odor of the water. While this process improves the water's palatability, it doesn't eliminate all contaminants.
What Filtration Doesn't Remove
It's important to note that carbon filtration may not remove substances like nitrates, metals, and other dissolved solids. Therefore, while spring water is often perceived as naturally pure, it can still contain certain impurities after filtration.
Spring Water vs. Tap Water Filtration
The reference suggests that spring water and tap water filtration are similar. Both often undergo a carbon filtration process at the bottling or treatment facility. This can blur the lines between the filtration methods employed for each water source.
In summary, the primary filtration method for spring water involves carbon filtration, mainly to remove chlorine and improve taste. However, other contaminants may still be present after this process.
