Good idea for a test, but if the surfactant came down as a slug several days ago, the Influent won't foam now. This is a great thing to do in the future as soon as foam is seen in the aeration tank - grab yesterday's and today's Influent sample and aerate it. I'll add this to my list of handy tests.
