Am I visualizing your proposed setup correctly? -- Water come in in a,
say, 1" pipe, at the end of which a solution is added. Then it joins a
12" pipe -- mixing chamber -- and then goes back to 1" pipe. Is that
I seriously doubt that you will get good mixing, because chances are
that there will be laminar flow in the 12" pipe. To prevent that, just
add some baffles in the 12", or some *large* "bioballs" or "saddles" to
interrupt the laminar flow and mix the water.
Aside from that, it seems like a practical labor-saving device.
