Characterization of Activated Sludge Foams from Two Plants
Publication: Journal of Environmental Engineering
Volume 116, Issue 5
Abstract
Activated sludge (AS) foams from two wastewater treatment plants are characterized. The foams contained a significant amount of substrate and lipid. Their contents varied from plant to plant and even within the same plant. The microbial activities of foam in terms of glucose utilization and ATP levels were similar to those of mixed liquor. Foams were subjected to acid hydrolysis and heat treatment as an alternative disposal method. The hydrolyzed byproducts were readily biodegradable in a standard AS process.
