Why ozone could be the answer to your bad tasting, brown, smelly water!
The effectiveness of iron filtration with ozone is proven by the thousands of installations across the globe leveraging its powerful oxidation and reduction of iron, manganese, and IRBs. Ozone technology is dependable and continues to evolve to benefit more applications within the water treatment industry.
An iron filtration system with ozone such as the Ozotech Enhanced Oxygen Generator technology (EOG) coupled with ozone resistance approved control valve provides a water treatment system can be designed to oxidize, clean, and filter water while supplying enhanced antimicrobial protection against nuisance bacteria such as iron-related bacteria (IRB), sulfate-reducing bacteria, and related odors.
In comparison to chlorination, ozone has proven to show sustainable disinfection effectiveness against microorganisms. In addition, its oxidizing properties may also transform the iron, manganese, and sulfur as well as reduce taste and odor problems. Ozone oxidizes the iron, manganese, and sulfur in the water to form insoluble metal oxides or elemental sulfur, which are then then removed by filtration.
Ozone is a powerful oxidant, far more than oxygen, and has many industrial and consumer applications related to oxidation. Low level ozone systems are designed to work with iron filtration systems and engineered to produce less ambient ozone levels below the OSHA limit of 0.1ppm established to protect workers exposed to incidental, industrial, incidental ozone production. All ambient oxidizers have an OSHA limit.
How an Iron Filtration System with Ozone Works
An iron filtration system with ozone is a water treatment system designed to oxidize, clean, and filter water while supplying enhanced antimicrobial protection against nuisance bacteria such as iron-related bacteria (IRB), sulfate-reducing bacteria, therefore related odors are reduced.
There are three steps in an iron filtration system with ozone:
- Raw water enters the filter and first passes through the ozone dome where the Ferrous Iron is oxidized and made ready for filtration. Next, the oxidized water passes through the filter media to remove the oxidized (Ferric) iron, and related taste and odors from the water.
- The system cleaning begins with a backwash cycle that reverses the flow of water to lift the filter media and wash trapped iron particles to the drain. After each system backwash, ozone is activated and drawn into the tank, exposing the working parts of the valve, the dome, and upper basket of the tank and throughout the media.
- During this draw cycle, ozone is generated and drawn into the tank to re-establish the ozone dome also to recharges the filter media. During the regeneration the tank and media are exposed to a new dose of ozone gas. This gas will remain in contact during the draw cycle and the 20–30-minute half-life reduction of ozone (O3) back into oxygen. Half-life reduction rate will vary depending on the water temperature and pressure.
Key Benefits of Using Ozone for Iron Filtration:
Effective Oxidation: Iron in water is often present in the ferrous (Fe2+) form, which is not easily removable through conventional filtration methods. Ozone is a strong oxidant and can efficiently convert ferrous iron into ferric (Fe3+) iron. Ferric iron can be easily filtered out or precipitated, making the water clearer and free from iron.
Cleaner Tanks and Valves. Most oxidizing filtration medias lose efficiency when they are coated with biofilm from organisms within water. The repeated introduction of ozone to the media re-oxidizes the media and reduces the buildup of biofilm allowing the media to work as it was designed, and the tank and media stay clean and in optimal operating condition.
Longer Lasting Filters. The use of ozone reduces IRB build-up and keeps a system clean by converting the incoming ambient air (20 percent oxygen and 80 percent nitrogen) into ozone and discouraging rather than encouraging IRB growth and working effectively and efficiently for longer periods of time. Long-lasting results using ozone are achieved with a small amount of scheduled, annual maintenance, decreasing the number of service calls needed.
Higher Quality Water. By reducing the root causes of the bad taste, color and odor, iron treatment systems with ozone provide more effective filtration equating to cleaner, better tasting water.
No Harsh Chemicals. A sustainable way to filter water without using the harmful chemicals other filtration systems may use.
It is important to note that ozone-based iron filtration systems should be designed and operated correctly to achieve optimal results. Consulting with water treatment professionals or experts can help ensure that the system is appropriately sized, and proper controls are in place to maximize the benefits of using ozone for iron filtration.
