Some folks gastro intestinal systems don't gracefully tolerate high concentrations of chlorophyll. Google chlorophyll poisoning.
As I've noted, it's most efficient to not extract it in the first place, but assuming its late for that discussion, there are ways to remove the chlorophyll or deprotonate it into pheophytin that tastes earthy vis a vis green. They all come with efficiency/product losses, but are not excessive and are the cost to play at this point.
Setting the solution in strong UV light will deprotonate the magnesium ion in the tail of the chlorophyll molecule, but not remove the pheophytin that it turns into. UV also destroys some of the target elements.
Wine producers remove unwanted polar elements using a bed of activated charcoal resting on a diatomaceous earth to filter out the carbon dust. It works with our solutions as well, and again there are some losses to the charcoal.
Column chromatography will do it, with some losses.
Lastly, if you have a really nasty solution that you want to scrub, you can do non polar/brine wash for the concentrate:
