I have done several pilot studies with VSEP filters on phosphoric acid. The goal wasn't increasing concentration, but that was a side effect. The removal of impurities causes an increase in strength of the filtrate.

There is also a commercial process using membranes to make purified phos acid - look up kemworks.com
