Abstract:: Coagulation and flocculation are commonly used in drinking water treatment as a means of destabilizing and aggregating particles and promoting adsorption of dissolved organic carbon (DOC). In practice, jar tests are used to determine optimal conditions for the removal of turbidity and DOC. However, beyond the inferences that can be...

Creator:: Xu, Zhihua
Abstract:: Reverse osmosis (RO) is being increasingly used in treatment of domestic wastewater secondary effluent for potable and non-potable reuse. Among other foulants, dissolved biopolymers, i.e., proteins and polysaccharides, can lead to severe fouling of RO membranes. In this study, the roles of RO membrane surface properties in membrane fouling by...

Creator:: Ünsal, Abdurrahman
Abstract:: Power quality has become an important concern to both electric utilities and end users due to the increased use of non-linear loads in modem power systems over the past decade. Nonlinear loads inject harmonics into the power system and thus may lead to poor power quality and lower power factor....

Creator:: Lauchnor, Ellen Grace
Abstract:: This dissertation explores the physiology and gene expression of the ammonia-oxidizing bacterium Nitrosomonas europaea in surface-associated bacterial communities, or biofilms. Biofilms of N. europaea were cultivated in drip flow reactors for several weeks and gene expression microarrays were used to detect 240 genes differentially expressed between the mature biofilms and...

Creator:: Harrington, Stephanie J.
Abstract:: The conventional advection-dispersion equation cannot adequately describe all processes driving solute transport in heterogeneous systems. This dissertation focuses on the individual influences of both chemical (Chapter 2) and physical processes (Chapters 3 and 4) which affect solute transport. In Chapter 2 we analyzed uranium transport in natural sediment using the...
