Sulfur Removal System Options
While there are a number of ways to remove sulfur from your water, a combination of oxidation and filtration is one of the most cost-effective and reliable. When hydrogen sulfide is exposed to oxygen, the sulfur is separated and becomes a solid that can then be filtered out. At US Water Systems, we recommend hydrogen peroxide as a relatively inexpensive yet very effective oxidizer for use with a sulfur filter. It’s safe, it’s powerful, and it works.
Both of our inFusion systems, inject a continuous flow of hydrogen peroxide into the water, causing an immediate reaction with the hydrogen sulfide – as well as any iron or magnesium that are in the water. These elements become insoluble, meaning that they are no longer dissolved in the water and can be removed. These systems also utilize backwashing catalytic carbon filters that capture and hold the solid particles, their catalytic nature promotes the oxidation process and, in fact, adsorbs and oxidizes some of the hydrogen sulfide itself. This makes the entire system more effective.
Small amounts of sulfur can also be removed from drinking water with a reverse osmosis filter or a granulated activated carbon filter, but neither method is very effective on its own. Oxidizing filters that use potassium permanganate are more effective, although this chemical is a poison that must be handled and stored carefully. Chlorine is a common oxidizing agent, but it is less effective than hydrogen peroxide, requires longer contact time, and you may need an additional filter to remove the excess chlorine from your water.
