How the Eradicator Air Induction Filtration (AIF) Systems Work
Air is a powerful oxidizer for both iron and sulfur. Historically, air has been utilized in water treatment through aeration tow -
ers, injection of compressed air, or by using an inline venturi. Aqua Systems AIF technology is a breakthrough because
air is introduced through an induction venturi that is built into the control valve. This allows a single tank to be used as an
aerator and a filtration system.
The AIF systems retain a head of air in the top of the tank during each treatment cycle. Each regeneration process purges
that air from the tank before backwashing the media bed. Fresh air is introduced after the media has been cleared of the
debris it has filtered from the water. The fresh air is introduced through the venturi. As the air is introduced, it displaces the
water in the tank, exposing the media to fresh air. This exposure of air to the media sets up oxygen sites on the surface of
the media, which provides the action it needs to perform. The head of air begins the oxidation process, while the oxygen
sites on the media complete the process by holding the iron and sulfur in the media bed.
Limitations of the AIF Systems:
• In order for the AIF Iron Filters to function, the pH of the source water must be at or above 7. If the pH is
below 7, you must include the pH adjustment option when treating iron.
• The water supply must have adequate flow and pressure to backwash the applied system. Be sure to
reference the required backwash rate of a specific model when considering an application. The minimum
requirement for the smallest system is 5 gallons per minute while maintaining a minimum of 20 psi.
• Water supplies may change over time. It is possible for the source water conditions to deteriorate beyond the
capability of an applied system months, or even years, after the initial installation.
• There will always be some effervescence to the water with this system. This effervescence is caused by
residual air in the water. This milky appearance is most noticeable immediately after a new installation. It
could take 30 to 90 days to settle out as the media fully absorbs the water, and expels the excess air.
• If you have a reverse osmosis (RO) system, the air will be noticeable in the drinking water as well. In fact, the
membrane in the RO system will actually concentrate the air and make it more noticeable. This too will soon
settle to a minimum.
• This residual air in the effluent water may loosen iron, or sulfur, build up from plumbing systems. If you are
installing an AIF system where the water pipes have a build-up inside, it may take a few weeks, or more, to
clear out the water lines. You may notice debris expelled from the tap on occasion as this build up is released
and cleaned from the plumbing system. This may require you to clean the faucet aerators, until the debris is
clear.
• You should never introduce chlorine into an AIF Iron Filter . Chlorine, and other strong oxidizers, will
damage the special media.
