Description:
This evaluation addresses the product quality, waste reduction, and economic issues involved in recycling metalworking fluids through a mobile recycling unit. The specific recycling unit evaluated is based on the technology of filtration, pasteurization, and centrifugation. Metalworking fluid recycling was found to have good potential as a means of waste reduction and cost saving. Product quality was evaluated by conducting performance tests and by chemical characterization of the spent, recycled, and virgin fluids. The performance of the recycled fluid appeared promising. This report was submitted in partial fulfillment of Contract Number 68-CO-0003, Work Assignment 0-06, under the sponsorship of the U.S. Environmental Protection Agency. This report covers a period from December 1, 1990 to June 15, 1992, and work was completed as of June 15,1992.
