AIR INJECTION OXIDIZING FILTER SYSTEM = AIO
Last Updated: 09/08/2018
An AIO Filter ( AIR INJECTION OXIDIZING FILTER SYSTEM ), when properly applied, is an efficient and cost effective system for the removal of iron and sulphur. An AIO system maintains a compressed “air pocket” in the top of the tank while the system is in service. As the water passes thru the air pocket, iron and sulphur are oxidized. Additionally, dissolved oxygen is added to the water. An AIO filter media bed then removes the iron and sulphur that has been oxidized from the water ( traps in the media bed ).

A daily backwash will remove accumulated iron and replenish the filter media bed. The regeneration process also adds a fresh air pocket to the system.
Application Parameters pH (Minimum) 6.8 and Iron (Maximum) 7 ppm and Sulphur (Maximum) 8 ppm.
Note: Three different medias are used depending on whether the problem with the water is primarily IRON or Hydrogen Sulfide odor.

*** We do NOT sell this system -- We can get most parts, if you have part numbers or can provide descriptions with photos of what have and what you think you need.

** Here is a link to Service / Installation Manual for a popular Brand of AIO ( sold through Nelsen Corporation ),

https://www.nelsencorp.com/customer/docs/SKUDocs/Nelsen-AIO-Manual.pdf

The Media can be BIRM ( iron removal ), Catalytic Carbon ( odor removal ) or Katalox Light ( a combination of Iron and Odor removal possible ).
It all depends on the application ( what is needing to be REMOVED from the Water - Iron or Hydrogen Sulfide and the LEVELS of these in the source water ).

And the two critical parts used to "convert" the Valve are:
1 ) Check Valve on the Inlet to prevent the "air" from escaping.
Here is photo of this used with a Fleck valve,


2 ) A screen ( and air check ) used on the Brine Connection to "draw" the AIR into the tank ( during the "suction" cycle ).


*** NOTE: We do not currently sell either of these parts. Just as we do not sell the Valves or System that use AIO.
And for "iron removal", see more information -
"Do I need an Iron Filter?"
And for odor issues - "Odor - Sulfur ( Hydroge Sulfide ) in your water"
