Swimming Pool Iron Removal Filters - High-efficiency Media For Oxidized Iron & Hydrogen Sulfide Removal, Periodic Regeneration With Potassium Permanganate

These Swimming Pool Filters are used for removal of dissolved iron which are generally present in the form of lower oxides.

These filters are used for removing both oxidized iron and iron in solution. The practical upper limit of iron concentration for these filters is 5 ppm. The filter media is also capable of removing small amounts of hydrogen sulfide. The filter media has three functions :

* It acts as an efficient filter in removing oxidized iron and sediment.
* It acts as a compact catalyst in augmenting the union of oxygen and dissolved iron in water to form oxidized (filterable) iron (the water must contain at least 0.1 ppm oxygen for every 0.7 ppm of iron).
* In case where the water has little or no oxygen the media will give up some of its own store of oxygen to oxidize iron.
* The media must be regenerated periodically with potassium permanganate (depending upon oxygen content of water) to restore the media.
* Optional regenerant systems are available to facilitate regeneration. pH must be at least 6.8 for efficient application and temperature should not exceed 120A F. Chlorine or potassium permanganate may be fed into the water ahead of the iron filter to aid in the oxidation of iron.
