actualy they will, just a little harder to make it work.

I am thinking of playing with the idea on my new fresh water tank I am going to builds.

Actually there are a few protein skimmers designed for freshwater applications only. We have seen units available for ponds and there has been several articles in Ponds USA dealing with DIY units for ponds. We have a large Sanders freshwater protein skimmer operating on our koi quarantine system which happens to also displayed in The Reef Aquarium Volume 3. The key is maximum aeration through specialized ceramic air stones being fed by approximately 20 l/min of air. This particular skimmer stands 7 feet and removes high levels of organic waste. The foam is less frothy but rich in organics. We saw various models at the Interzoo in Germany last year but again, most are marketed towards large applications. Expect to see smaller versions in the years to come particularly with the increase in ozone use with smaller freshwater aquariums in Europe.

Try adding calcium to fresh water and then try a protein skimmer.
Call me nutz but I have seen whirlpools running with no bubbles then by adding fine calcium the whirlpool begins to lather up. I guess It would be an neat experiment in a empty tank.

I have seen in waste water treatment plants use rubber type membranes that diffuse air into the tanks. They generate a fine enough bubble for fractionation purposes.

Schuran makes a FW skimmer.

But really, and this is strictly IMO, why would you need a FW skimmer? Are FW tanks not easy to maintain..?
