Description:
A roller compression Extractor® that extracts fluids from reusable sorbent pads was evaluated as a method of waste reduction. The extraction device, evaluated for industrial fluid users in New Jersey, was found to be effective in recycling unpleated sorbent pads, especially for low-viscosity fluids. The unpleated sorbent pads can be reused for at least eight times for low-viscosity fluids and up to three times for medium-viscosity fluids. However, the Extractor® cannot be used for pads soaked with high-viscosity fluids. Annual savings, up to 51% and 75%, would be possible for pads reused two and eight times, respectively. The cost per use can be as low as $1.19 for eight reuse cycles, versus $4.80 for single usage. The savings come primarily from cost and volume reductions in sorbent pad disposal. The number of drums needed for pad disposal would be reduced 73% and 93% if pads are reused for two and eight times, respectively. 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 February 1991 to November 1991, and the study was completed as of November 30, 1991.
