Pyrolox Media Replacement for Iron, Manganese, and Hydrogen Sulfide Removal
Iron, manganese, and hydrogen sulfide, referred to as troublesome trio, reap havoc on plumbing systems. As little as 0.05 ppm of manganese, 0.5 ppm of iron, and less amount of sulfide can cause staining and rust of plumbing systems. To battle this trio, people have used Ion exchange water softeners and Oxidation/Reduction media. Ion Exchange works only on dissolved iron and manganese, but not sulfur, and imparts a foul smell to the water. So, it is best to apply oxidation media treated with a coating of Manganese Dioxide.
There are various media such as Birm, Pyrolox, Filox, and Greensand Plus available in the market. All these media have different proportions of manganese dioxide coatings. The one that is widely used and effective is Pyrolox.
What is Pyrolox?
It is an NSF certified natural mineral form of Manganese Dioxide and a granular water filtration media. Pyrolox effectively reduces iron, manganese, and hydrogen sulfide from groundwater. It is an engineered filter media that is extremely dense and black and provides superior performance as compared to other manganese dioxide coated media.
How Pyrolox Works?
Hydrogen Sulfide, Iron, and Manganese are dissolved in water and cannot be removed by the filter directly, they need to be oxidized and precipitate into large particles for effective removal by the filter. Pyrolox acts as a catalyst oxidizing the contaminants when they come in contact with filter media and strains them.
With this process, the oxidized solids coat the surface of the media and its oxidation capacity is reduced. The trapped particulates are removed from the media with a powerful backwash cycle. Most filters backwash every 2 to 3 days, but it is essential that Pyrolox media is backwashed daily to continue operating or it will get clogged and stop working eventually. Also, it is recommended that Pyrolox is installed with an underbed as without it the filter can have a poor backwash distribution.
The Pyrolox media works best at a pH range of 5 to 9, however, the ideal pH is between 6.5 and 7.
Is Pre-Treatment Required?
Pyrolox acts as a strong oxidant, but pre-treatment is usually recommended when iron, manganese, and hydrogen sulfide are over 2 ppm. Chlorine injection is applied in a retention tank to maintain and further augment the long-term performance and removal capacity of media.
What is the Life Expectancy of Pyrolox media?
The media lasts for an indefinite time. However, about 10-15% is lost per year due to attrition or lost during backwash. To replenish the lost media, Pyrolox media replacement is recommended. This further enhances the removal capacity allowing for better performance.
What are the Advantages of using Pyrolox?
A naturally mined ore, Pyrolox is quite effective in the removal of iron, manganese, and hydrogen sulfide from the water. Apart from this, there are various benefits of using Pyrolox filtration media.
- Protect your plumbing systems from rust and stain
- Durable material with long service life and low natural attrition
- Chemical regeneration not recommend often
Pyrolox is quite effective in the removal of impurities from water and allows the system to work without pre-treatment.
