HOW DOES THE CHEMICAL FREE
AND AIO IRON FILTER WORK?
This filter works by adding oxygen to the incoming water by
passing it through a bubble of compressed air. The water is
then passed through a special filter bed composed of calcium
carbonate and magnesium oxide with a filter sand bed.
The special media not only increases the pH of the water to enhance iron removal, but also acts as a
physical barrier to trap iron precipitate.
As more water passes through this iron filter, the oxygen in the unit is used up, and the media gets
loaded with iron. The regeneration process then begins in order to replenish the supply of oxygen, and
to backwash the precipitated iron trapped in the media bed.
The iron removal efficiency will be more effective with high pH water.
Replenishment of this media that raises pH will be required periodically, depending on how low the raw
water pH level is, the amount of manganese (Mn) present in the water and usage rate. Over a period of
time, it may become necessary to add more media to the unit. Adding media is necessary only when
water has low pH or manganese is present.
Sulfide problems in surface water sources are much less frequent because of the natural aeration that
occurs in most flowing surface water sources. Aeration is the most common treatment method in terms
of volume of water treated annually because it’s inexpensive, easy to maintain and doesn’t produce
potentially harmful reaction products such as tri-halo-methanes (THMs).
