5, respectively. These data were complied based on actual performance data obtained
from filter press manufacturers, such as those listed in Appendix A.
2-3.3.3 Case Studies. Following is a summary of referenced case studies from the
literature. Although the studies are primarily based on the results of dewatering
municipal wastewater sludge using filter presses, the information applies to HTRW sites
EPA (1979, pages 9-59 through 9-61): Provides the performance results of a
fixed-volume press application for wastewater.
EPA (1987, pages 114 through 117): Provides a summary of performance
results and operating and maintenance problems from a survey of 50 filter
press wastewater applications.
WPCF (1983, pages 87 through 92): Provides the results of several wastewa-
ter applications for both fixed-volume (low [590 kPa (100 psi)] and high [1550
kPa (225 psi)] pressure) and variable-volume filter press installations.
WEF (1992, pages 1218 through 1222): Provides two case studies and per-
formance results for pressure filter presses at five wastewater installations.
