These single-tank green sand filters are, I believe, a thing of the past in domestic applications and I will say that is a very good thing. Staying with the green sand as a media, some manufacturers later came out with semi-automatic iron filters. These were just like the single-tank units but with a reserve tank, or "brine" tank, if you will.
