Implementation of the US Environmental Protection Agency's Metal Finishing Facility Pollution Prevention Tool (MFFP2T)

摘要

To help metal finishing facilities meet the goal of profitable pollution prevention, the U.S. EPA is developing the Metal Finishing Facility Pollution Prevention Tool (MFFP2T), a computer program that estimates the rate of solid, liquid waste generation and air emissions. This program will allow users to insert computer models of standard metal finishing processes into the proposed manufacturing process, thereby estimating wastes generated by the metal finishing process lines. This paper will discuss the mathematical models used by MFFP2T to model the plating, cleaning, and rinsing processes. Additionally, the chemical equilibrium models utilized to estimate the sludge generation rate in various process tanks will be presented. The results of the individual models are combined to create a model of the overall waste generated by the process. The user will then be able to model the effects of changes to processing conditions on the quantity of wastes generated.
