Abstract	A s numerous ozone-depleting compounds became legislated out of use, a large number of companies chose aqueous cleaning solutions as replacement alternatives to solvent degreasing. In the early transitional days, many process and manufacturing engineers were concerned that aqueous processes would reduce part quality and throughput while creating additional waste and wastewater treatment problems and costs. Other alternatives include drop-in semi-aqueous or solvent-based cleaning systems. However, these are not without their own problems, namely employee health concerns, flash points and possible worker discomfort due to odors. The University of Massachusetts at Lowell’s Toxics Use Reduction Institute showed aqueous cleaning’s viability in industrial settings. Aqueous cleaning has provided a sound alternative to vapor degreasing in as many as four out of five applications that the Institute reviews on a laboratory scale for industry clients in a state exceeded only by California and New Jersey in its environmental strictness. Modern closed-loop aqueous cleaning systems remove contaminants from both the cleaning bath and rinse water, and compared to solvent cleaning systems, may be relatively inexpensive to install. Recycling can help reduce or eliminate liquid waste by trading dilute liquid waste for more easily disposed solid waste in the form of spent filters or concentrated sludge. Recycling can also help reduce detergent consumption in order to get more parts clean per pound or gallon. It may also save time and increase throughput while reducing system set-up requirements.
