Project Summary: Top-Feed Vacuum Filtration of Waste-Activated Sludge

摘要

The objectives of the project were to evaluate the effectiveness of a top-feed vacuum filter on a prototype basis and to compare the performance and cost-benefit relationship of a top-feed vacuum filter with conventional bottom-feed vacuum filter. This project evolved out of earlier work done under EPA Grant No. WPRD 71-01-68, which studied the performance of a pilot-scale top-feed vacuum filter. A significant drawback of the pilot-scale study was that no statistically valid comparison could be made between the pilot-scale top-feed vacuum filter and a full-scale conventional botton-feed vacuum filter. Thus, an evaluation of two full-scale units, operating on a side-by-side basis, was undertaken.
