Experiments In Aerobic And Anaerobic Biodegradation Of Trichloroethylene, Qiong Liao

Theses

The removal of trichloroethylene (TCE) from industrial waste has been intensively studied in recent years, Biodegradation has been determined to be an effective treatment for TCE in the environment. Many researchers have studied the biodegradation of TOE and obtained successful results based on the use of specific isolated bacteria. At the NJIT Biotechnology Laboratory, a new method is being developed in which immobilized activated sludge is used to degrade several toxic chemicals in various reactor configurations. The objective of this research is to determine if these methods can be extended to treat TCE.

Experiments In Aerobic And Anaerobic Biodegradation Of Methylene Chloride Using Activated Sludge, Vivek Chandrakant Sinkar

Theses

Biological removal of methylene chloride was studied under aerobic and anaerobic conditions using activated sludge cultures. Shaker flask experiments were conducted to test the ability of the microorganisms to degrade methylene chloride under aerobic conditions. Hydrogen peroxide was used a as source of dissolved oxygen to minimize physical removal of methylene chloride due to aeration. The effect of secondary substrates like glucose, cellulose acetate, ammonium acetate and nutrient broth on biodegradation of methylene chloride was studied. Biodegradation in the presence of surfactant and alkaline stress was also investigated.

No significant degradation was observed in all aerobic experiments.

Anaerobic sludge was …
