The Biodegradation Of Phenol And O-Chlorophenol Using Activated Sludge Bacteria, Jeffery Colish
Theses
The biological degradation of phenol up to 500 ppm and 0-chlorophenol up to 40 ppm was studied in an aerated 4.0 liter hatch reactor using activated sludge bacteria from the Livingston, N.J. wastewater treatment plant. From the concentration versus time data, kinetic rate constants were determined for phenol (@ 100 ppm) and o-chlorophenol (@ 20 ppm and 40 ppm). Air stripping was determined to be an insignificant removal mechanism for the compounds studied.
It was noted that the acclimation times decreased with repeated exposure to a particular concentration of phenol or o-chlorophenol, and that the activated sludge bacteria first had …
