The electroplating industry has faced tremendous challenges in maintaining its economic competitiveness as well as improving its environmental performance in the global economy. It is recognized that much of the generated waste is avoidable, and reduction of such avoidable waste could significantly reduce the consumption of chemicals, energy, and water. Proactive source reduction can improve not only environmental quality but also economic performance. This type of source reduction, which could be called Proactive Pollution Prevention, can be achieved through applying advanced sustainability-bearing process systems engineering techniques, i.e., the fundamental system modeling and simulation techniques.In this book, the process models developed for electroplating systems are reviewed and selectively adopted. These models are embedded in a computer aided simulation tool, which is based on MATLAB platform. The tool has been used to conduct a comprehensive simulation of electroplating systems. It can characterize the dynamic operations of cleaning and rinsing operations, where chemicals, energy and water are consumed.
