The Biodegradation Of Phenolics Using Mixed Liquor From Passaic Valley Sewerage Commissioners Plant, Newark, New Jersey, Daewon Pak
Theses
The biological degradation of phenol, O-chlorophenol, and 2,6-dichlorophenol was studied at room temperature in aerated 5 liter batch reactors using mixed liquor from Passaic Valley Sewerage Commissioners Plant (Newark, New Jersey). From the concentration versus time data, kinetic rate constants were determined for phenol (at 100 ppm), 2'-chlorophenol (at 20 ppm), and 2,6-dichlorophenol (at 10 ppm). Air stripping and adsorption were determined to be insignificant removal mechanisms for the three compounds studied.
It was noted that the biodegradation rates increased after the organisms were acclimated to 100 ppm phenol. In addition, on substrate exposure, the degradation rate increased from the …
A Comparison Of The Biodegradation Of Phenol And O-Chlorophenol Using A Municipal Mixed Liquor And Three Commercial Microbial Preparations, Nigel P. Mcmullen
A Comparison Of The Biodegradation Of Phenol And O-Chlorophenol Using A Municipal Mixed Liquor And Three Commercial Microbial Preparations, Nigel P. Mcmullen
Theses
The biodegradation of phenol and O-chlorophenol was studied in six-liter batch reactors, using a municipal mixed liquor (from the Livingston, NJ treatment plant) that had not previously been exposed to either of the substrates. In addition, three commercial microbial preparations: BI-CHEM (Sybron), Hydrobac (Polybac), and LLMO (General Environmental Science), were tested alone and in combination with the municipal mixed liquor.
It was found that the municipal mixed liquor performed significantly better than any of the commercial preparations by themselves. When the commercial preparations were mixed with the municipal mixed liquor in a ratio of 1:10 it was found that the …
