Fate Of Estrogens In Anaerobic Digestion And Their Removal In Advanced Oxidation, Shubhajit Sarkar
Electronic Thesis and Dissertation Repository
Estrogenic compounds are most significant endocrine disrupting compounds (EDC), which are of primary concern due to their widespread presence in the aqueous environment and also due to their adverse impact both on aquatic life and potential risk to human health. Conventional wastewater treatment plants are not designed to remove EDC, with biosorption on biosolids as the predominant removal mechanism. Anaerobic digestion is one of the most preferred processes employed for sludge stabilization in wastewater treatment plants. Advanced oxidation processes (AOPs) are seen as promising technologies for removal of estrogens from the environment. In this research, a controlled degradation study of …

Numerical Simulation Of An Open Channel Ultraviolet Waste-Water Disinfection Reactor, Rajib Kumar Saha
Electronic Thesis and Dissertation Repository
The disinfection characteristics of an open channel ultra-violet (UV) wastewater disinfection reactor are investigated using a computational fluid dynamics (CFD) model. The model is based on the volume of fluid method to capture the water-air interface, the Lagrangian particle tracking method to determine the microbial particle trajectory and the discrete ordinate model to calculate the UV intensity field. The numerical predictions are compared with the available experimental data to validate the CFD model. A parametric study is performed to understand the effects of different parameters on the disinfection performance of the reactor. The hydraulic behaviour and the additive nature of …
