The Degradation Of Trace Pollutants In Wastewater, Christine M. Cheng

Theses

The effect of different treatments on the degradation of chlorinated organic pollutants in wastewater has been studied. The model compound investigated was para-chlorophenol. The different treatments used were ozone, UV irradiation, ultrasound, air flow and pure oxygen.

It is concluded that ozone has the greatest effect, ozone-UV irradiation follows closely behind, and UV irradiation has much less of an effect in degrading the p-chlorophenol.

P-chlorophenol was found to have an immeasureably slow degradation rate when treated with air even at an elevated temperature of 55°C.

The oxygen, at room temperature, showed a degradation of p-chlorophenol which, although small, was much …

Indicators Of Microbial Activity In Biological Treatment Of Hazardous Wastes, Alexander Mclean Sherrin

Theses

Three methods were used to measure the activity of mixed liquor from the Livingston, N.J. municipal wastewater treatment plant on exposure to phenol. The three methods were, substrate removal rate (SRR), dissolved oxygen uptake rate (DOUR), and the dye reduction rate (DRR). Parameters from each test were compared for reproducibility and ease of determination. The SRR test gave the most reproducible results, while the DOUR test was the least reproducible. Although the reproducibility of the DRR test was close to that of the SRR test, the DRR was more time consuming and required a greater degree of expertise and training. …

A Study Of The Dynamics Of Microbial Competition For A Single Resource In A Chemostat Between Reversible Attachment To Solid Surfaces, Pericles Theofilos Lagonikos

Theses

It is known that two microbial populations competing for a single non-renewable resource in a homogeneous environment with time-invariant inputs cannot coexist in a steady state. The case where two microbial populations exhibiting reversible attachment to the walls of a chemostat compete for a single resource is studied theoretically. Because of the cell's attachment to the walls, the environment is no longer homogeneous. The present study considers the case where the attached cells form no more than a monolayer. The Baltzis-Fredrickson model is used to represent the attachment to the walls. In one system the attachment of cells of the …

Zeta Potential Measurements Of Biological Flocs Using A Streaming Potential Cell, Wayne James Gallagher

Theses

A streaming potential apparatus was assembled and tested. Its purpose was to characterize the surface of biological flocs in a wastewater environment. Samples of mixed liquor were obtained from the Passaic Valley Sewerage Commissioners wastewater treatment plant in Newark, New Jersey. Filtered mixed liquor was passed through a bed of the floc particles in the streaming potential cell, and the electric potential across the cell was measured as a function of the differential pressure drop. From these data, the zeta potential was calculated using the Helmholtz equation. Values of -0.88 and -0.44 millivolts were obtained for two mixed liquor samples.

Investigation Of Water-Binding Properties Of Industrial Sludges Using Thermal Analysis As A Monitoring Tool, Ron Josephson

Theses

As part of a program to develop new and more cost-effective dewatering approaches for industrial hazardous wastes, sludges and synthetic "model" materials were analyzed by thermal methods in an attempt to comprehend their water-binding qualities and differentiate free and bound water. These thermal methods included Differential Thermal Analysis (DTA), Thermogravimetric Analysis (TG), and Differential Scanning Calorimetry (DSC). Industrial sludges and laboratory models were compared using both standard heating techniques and subambient cooling (to -60°C). This latter technique provides direct indication of the amount of free water. This information can be very useful in evaluating and improving dewatering techniques for industrial …
