Electrochemical Disinfection Of Municipal Wastewater Using Alternating Current, Xavier A. Chavez Reyes
Electrochemical Disinfection Of Municipal Wastewater Using Alternating Current, Xavier A. Chavez Reyes
University of New Orleans Theses and Dissertations
This research focused on chlorine-free disinfection of wastewater by complying with today's regulations. The equipment used was a continuous flow electrochemical reactor connected to an alternating current (AC) power supply. The electrodes used were made out of titanium coated with iridium oxide. To determine the inactivation of Escherichia Coli, a bacterial count method based on the USEPA method 1603 was used.
After several experiments it was determined that electrochemical disinfection using AC was not efficient and economic enough to be classified as a viable alternative to chlorine disinfection. It was demonstrated that chlorine can be produced by electrolysis using AC …
One-Dimensional Dynamic Modeling Of The Lower Mississippi River, Tshering T. Gurung
One-Dimensional Dynamic Modeling Of The Lower Mississippi River, Tshering T. Gurung
University of New Orleans Theses and Dissertations
The Mississippi River (MR) has been engineered with the development of the levee system, dams for flood control measures, jetties, revetments and dredging of the navigation channel. These alterations have reduced the replenishment of the sediment to the Louisiana Coastal area. To aid in the restoration planning, 1-D numerical models have been calibrated and validated to predict the river response to various changes such as channel modifications, varied flow conditions and hurricane situations. This study utilized the HEC-RAS 4.1 and the CHARIMA (Dr. Forrest Holly, University of Iowa). The models were calibrated for hydrodynamics and sediment using Tarbert Landing discharges …
3-D Hydrodynamic And Non-Cohesive Sediment Transport Modeling In The Lower Mississippi River, Grecia A. Teran Gonzalez
3-D Hydrodynamic And Non-Cohesive Sediment Transport Modeling In The Lower Mississippi River, Grecia A. Teran Gonzalez
University of New Orleans Theses and Dissertations
The purpose of this research is to develop a 3-D numerical model on the Lower Mississippi River to simulate hydrodynamics and non-cohesive sediment transport. The study reach extends from Bonnet Carré Spillway (RM 127) to Head of Passes (RM 0). Delft3D with sigma coordinates was selected as the river modeling tool. This model River domain is characterized by a complex distributary system that connects the Mississippi River to the Gulf of Mexico. The boundary conditions were: water levels in the Gulf and Head of Passes; and discharges upstream. For the calibration, there are observed data for both types of boundary …
Hydrodynamics And Salinity Of Pontchartrain Estuary During Hurricanes, Sina Amini
Hydrodynamics And Salinity Of Pontchartrain Estuary During Hurricanes, Sina Amini
University of New Orleans Theses and Dissertations
A hurricane is a combination of sustained winds, low atmospheric pressures and precipitation. Over the past decades, Louisiana has experienced several devastating hurricanes.
The east bank of the City of New Orleans is bounded by Lake Pontchartrain to the North and the Mississippi River to the South. Lake Pontchartrain is a brackish system connected to the Gulf of Mexico through Lake Borgne to the East. As a Hurricane enters the Estuary from the Gulf of Mexico, it imposes a sustained surge of a few meters which may lead to flooding in areas which are not protected by levees. These flood …
