Characterization Of Microorganisims After Feeding With Phenolic Compounds : Comparing A Domestic Sludge To An Industrial Sludge, Dianne Adamowitz

Theses

This study examined the effects of phenolic compounds on the populations in mixed liquors obtained from two very different treatment plants: the Passaic Valley Sewerage Commissioners plant in Newark, and the Livingston, NJ municipal treatment plant. The dominant organisms were identified initially and after ten days exposure to phenol (100 ppm), and either 2-chlorophenol (20 ppm) or 2,6-dichlorophenol (10 ppm) in aerated batch reactors.

Results confirmed the remarkable similarity between the two mixed liquor populations, in spite of the significant differences in the operation of the two treatment plants.
