Attempting shower filter and foam fractionation

I'm trying to build into my shower filter a foam fractionator, but I'm not sure if it will work.
Using 4 large HDPE poly containers, I had 2x4" female threaded adapters spin welded onto the side to connect a 4" pipe as an outlet.
I'll be flowing water about 6ft over it with a Periha PB-16000 pump.

where did you get plastic containers from?

Regular HDPE tanks, I took it to Ronco Plastics and paid them to weld in 2x4" ports. Call them up they can do it.
