Filtering carbonated beer.

I just want to share that I filtered about 10.5 BBL of carbonated beer to kegs in about 2.5 hours.
I did not lose carbonation and I am as happy with the result as I can be.

First I want to say that the approach I took is not practical for homebrewer.
I used pump to pull beer out of bright tank that was at 13 psi and pushed it thru the filter at 17 psi to the receiving keg that was at 12 psi.

I used 1 micron cartrage and 20" X 4" Big Blue whole house filter.
Beer did not foam at all.

Good to know.

So the bottom line is that beer under pressure then filtered and recieved under pressure will maintain most of it’s carbonation.

Yes that is correct.
You need the pump to push it thru.

You’re using a centrifugal pump with a vfd?

Yes. Have Thomson centrifugal pump but not VFD.
