Description:
Product quality, waste reduction, and economic issues were evaluated for a technology designed to recycle metalworking fluids. mulsion-type fluids were tested at two sites and a synthetic fluid was tested at a third site. he specific recycling unit evaluated is based on the technology of filtration, pasteurization, and Centrifugation. his recycling unit is mounted on a truck which goes from site to site, performing the recycling at each customer location. he customer is charged a fixed fee for the service. etalworking fluid recycling was found to have good potential as a means of waste reduction and cost savings. he product quality achieved by this unit was evaluated by conducting performance tests and by chemical characterization of the spent, recycled and virgin fluids. erformance tests included tests for corrosion resistance, emulsion stability, foaming resistance lubricity and biological resistance.
