Now that I no longer have my "Well from Hell" issues (See the posting on that topic on this forum), I am on to another technical problem. I have about 2.0ppm soluble iron in the new well. On my old well, we had a 4 tank sand filter bed system with a large aeration bladder-less tank. That tank served the pressure tank function with a well pressure switch that caused a cycling and air injection, passive, for oxidizing the iron.
Now the new system. It looks like we need to reinstall a new aeration tank and airpump to feed the sand filter bank for collecting the iron. In this configuration, do we really also need an in line bladder pressure tank. The current one is 40 gallons, but the Franklin Controller Manual says that you only need 12 gallons for the 1.5 Hp pump. I don't see why we need 2 pressure tanks. The new bladder-less tank will be about 120 gallons.
Are there control stability problems with running the pressure sensor off the aeration tank line, and are there any other issues that would crop up if we pull out the pressure tank. I am obviously motivated to keep the tank count down.
We also have a seperate issue of how to cycle the air pump so that we get appropriate air injected into the aeration tank. The Franklin Controller that we have does not appear to have any tap for sensing when the well is pumping. It would seem that one would want a signal at a certian flow, otherwise let the air pump idle. The iron filter folks are talking about a flow meter, but that sounds expensive, ie. about $500.00 adder.
All comments are very welcome.
