HOW Does a CHEMICAL FREE FOK IRON & SULPHUR Filter Work?

These FOK Iron and Sulphur Filters are totally chemical free and don’t have any filter cartridges to change either. They just use air to oxidize the iron and sulphur from your water. This is how they work:
The systems draw air through its air intake in it’s advanced electronic control valve to form an air cap within the top of the media tank.
In every day use, water is sprayed through the air cap to begin oxidizing the iron and sulphur out of the water. The media traps the oxidized iron and holds it in place while the water flows into and up the riser tube to the whole house or cottage.
Every three days the air over media filter automatically reverses the flow and backwashes all of the media flushing the iron, dirt and sediment from the media and into the drain. Then the air cap is rebuilt but sucking water through the injector before the filter is put back into service to continue to oxidize and remove iron from your water. In the process it will also remove up to 1 ppm of manganese. I should mention that this system works fine at removing up to 7 ppm of iron and 2 ppm of sulphur with a ph of between 6 and 9, if you also want to remove manganese your ph will need to be at least 8.
There are no filters to change or chemicals added to your water.
