Sorry if this is covered elsewhere, but I wasn't finding it easily.
I realize one way to deal with chlorophyll in your extract is to not extract it. What I'm asking about though is how people are removing Chlorophyll from their concentrates and pros and cons of those techniques.
Thanks!
I suscribe to the school of not extracting the C-30 sized chlorophyll, plant waxes, or anthro cyanin molecules up front. They don't come from the trichomes,as do our targeted C-10 through C-22 molecules, so no reason to bring them along for the ride.
Once you have chlorophyll, you can polish it some using a brine hexane wash:

As noted by NM you can use carbon filtration, but even pre-wetting the filter media, losses of targeted elements are high as well.
Column chromatography also works. Here are the different fractions from a hexane solution through a column of mixed size silica chromatography beads. Of note is that there were low to none cannabinoids in the first or the last two fractions.
Lastly you can remove chlorophyll using fractional short path distillation.
As noted, you can UV bleach the chlorophyll to its breakdown products, which are amber instead of green, but they are still there.
