I'm not an engineer so I'm guessing at this. I think the main thing is to
create a mix of air into the water thoroughly enough that the Iron is
exposed to an aerobic condition, which is enough to create the iron oxide
precipitate. Anything that would rotate the bulk of the water in the
container through the jet in a reasonable rate of time (faster than
consumption rates) should do the trick, as long as it truly aerates the
water. I only know this through the work done by a colleague in southern
Illinois, who has left the system since. I never discussed with him the
actual equipment used.
