Iron In Your Water? Ozone Can Help.

Rusty stains. A sure sign of iron in your water.

High iron content in water often results in disagreeable metallic taste and unappealing color in cooked vegetables. Although not a health threat, iron bacteria thrive in this water and contribute to biofilm and discoloration. Dissolved iron eventually leads to ugly stains on fixtures and clogged pipes. Removing iron from your water supply is well worth the investment.

The most common piece of water treatment equipment for homeowners is the water softener. Your water softener is designed to remove calcium from the water. It may remove some of the iron, but iron is prone to stick to the resin bed and is difficult to flush out.

An iron filter is a much more effective method for removing iron. There are a variety of filter systems, but they all follow the two step process of oxidizing the iron and then filtering it out. Iron that is dissolved in water can’t be filtered out until it is oxidized or made into larger rust particles that are large enough to be filtered.

Simply aerating water containing dissolved iron will begin the oxidation process needed for filtration. This method is simple, but can introduce some new problems such as increased bacteria growth. It is also slower and difficult to control effectively.  

Some compact home iron filtration devices contain media which accelerates the oxidization process and also serves as a filter to remove the oxidized particles. Like a water softener, these systems require periodic back flushing and eventually require chemical regeneration. The effectiveness of these systems is dependent on PH levels and do not disinfect the water. Iron bacteria can still cause problems by leaving ugly stains on water fixtures.

Adding a chemical feed pump to introduce chlorine, calcium hypochlorite or potassium permanganate increases the oxidation. These systems are able to remove higher iron levels and also serve to disinfect the water. The disadvantage is the ongoing cost of dangerous chemicals.

Ozone is one of the most powerful oxidants. Using ozone to oxidize iron before filtration not only quickly oxidizes all the iron, it oxidizes magnesium and Sulfur compounds as well. Ozone also provides complete disinfection and leaves no chemical residue.  “Ozone can be very effective at treating well water for residential, commercial, or agricultural applications.” Ozone is powerful and requires robust, well-designed equipment to harness its power. Our CWS Ozone Water Filtration System will provide years of service.

Ozone has been used for water treatment for over a hundred hears. It is used extensively for bottled water treatment because it is an effective disinfectant and improves taste and color. Oxidation Technologies specializes in harnessing the power of ozone for a variety of water treatment needs.
