The 800 Iron Filter stores a “bubble” of air,
compressed by your well pressure, within the
media tank. As your water passes through the air,
the iron or sulfur is converted to a particle, which
is then trapped by the catalytic filter media in the
tank while the air “bubble” is gradually consumed
by the passing water.
For regeneration the unit first “backwashes” itself
removing any iron or sulfur particles it has trapped.
Next the system replenishes the “air bubble” by
drawing in atmosphere temporarily emptying the
tank of all water and transferring oxygen molecules into and on the surface of the media bed where all oxidation occurs. Finally the system then returns to the “service” position, again filtering your water.
