The recirc line would have to be flush to the inside of the lid, or even recessed a little so that it's drawing from the absolute highest point in the reaction chamber thus mitigating the size of the bubble buildup.

I'm probably not explaining this well enough. I'll see if I can dig up some photos or diagrams.

I think I know what your trying to explain. The outside of the lid is flat but the inside is actually cone shaped so that the recirculating line is at the absolute highest point, thus not allowing any bubbles to form at the top and pushing them down into the recirculating pump. The effluent line sits at the lowest part of the cone lid.
