Vacuum Skimming

Customer reclaims used paper. The paper scrap is introduced into a chemical solution and made into a slurry called pulp. The pulp is passed through screens to remove bits of plastic, etc. The next process is called de-inking to remove printing ink and glue. A surfactant is mixed into the pulp to loosen the inks and glues from the pulp. Air is then bubbled up through the slurry to float them to the top. What this customer needed is a way to vacuum off the foam created on the surface. Using a Model 120024 4" (102mm) Super Air Amplifier connected to a vacuum hood, the floaters were pushed towards the hood and vacuumed away.
