GLRPPR Sector Resource: Forward Progress in Reducing Oily-Wastewater: A Forward Osmosis, Small-scale Pilot at a Metal Fabricator

Title:
Forward Progress in Reducing Oily-Wastewater: A Forward Osmosis, Small-scale Pilot at a Metal Fabricator

Abstract:
Forward osmosis is the natural diffusion of water through a semi-permeable membrane from a solution of a lower solute concentration to a solution with a higher solute concentration. Taking advantage of this natural process, Illinois Sustainable Technology Center (ISTC) research staff successfully reduced volumes of three (3) common water-based industrial process waste streams at a small metal fabricator. Instead of conventional energy-intensive alternatives, researchers employed fledgling forward osmosis technology, using chemistry instead of energy to remove water from common process fluids.
