Draft Cleaner Technologies Substitutes Assessment (CTSA): Screen Reclamation - Chapter 5

EPA 744R-94-005a
September 1994

Substitute Comparative Assessment, Screen Reclamation Methods

Chapter 5 provides a comprehensive assessment of screen reclamation methods 1-4 and the automatic screen washer. When available, information is provided for each method and technology on occupational exposure and risk, population exposure and risk, performance of traditional and alternative systems, and the cost analysis of traditional and alternative systems. The discussion of the details of each method or technology includes an explanation of the particular advantages or disadvantages of that method or technology. The details, assumptions and uncertainties of each of the methodologies in this chapter are discussed in Chapter 3; referencing this chapter while reading Chapter 5 may eliminate the confusion that may occur due to the numerous exhibits.
