This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Municipal wastewater is being increasingly emphasized as a local, reliable source water supply for potable water. Potable reuse facilities frequently employ Full Advanced Treatment (FAT) trains, most often including microfiltration (MF), reverse osmosis (RO) and the UV/hydrogen peroxide (UV/H2O2) advanced oxidation process (AOP). However, the widespread implementation of FAT treatment is hindered by two major challenges: high cost and the disposal of RO concentrate (ROC). In this dissertation, we evaluated the potential of emerging AOPs, including ozonation followed by biological activated carbon (O3/BAC), the UV/chloramines AOP, and the UV/free chlorine AOP to deal with these two major challenges for FAT trains. We evaluated the application of O3/BAC to remove nitrate and organic contaminants from ROC to facilitate disposal to marine waters. We characterized the ability of the UV/chloramines and the UV/free chlorine AOPs to serve as more efficient alternatives to the UV/H2O2 AOP for the treatment of RO permeate. Chapter 1 introduces the FAT treatment process train, two of the major challenges facing these FAT trains, emerging AOPs to address these challenges, existing knowledge gaps and the objectives of this dissertation. Chapter 2 evaluates the feasibility of O3/BAC to treat RO concentrate at pilot-scale. The results suggest the potential for substantial synergy between potable reuse, and the removal of nitrogen and organic contaminants, enabling utilities to meet regulatory limits while partially offsetting the costs of producing a potable water supply. Chapter 3 develops a kinetic model for the UV/chloramines AOP when applied to RO permeate. The model is able to simultaneously predict the loss of chloramines and contaminants, such as 1,4-dioxane by determining quantum yields for chloramines and incorporating the subsequent reactions of NH2 radical. Initial cost estimates based on bench-scale results indicate UV/chloramines AOP using the residual chloramines in RO permeate could be a cost-effective alternative to the current UV/H2O2-chloramines AOP in some cases depending on the background chloramines concentrations and other constituents in RO permeate. Chapter 4 evaluates UV/free chlorine and UV/chloramines AOPs as alternatives to the UV/H2O2 AOP for treatment of RO permeate at pilot-scale. First, we characterized the speciation of the oxidants during AOP treatment and validated the ability of our kinetic models to accurately predict oxidant speciation. Second, we evaluated the ability of the different AOPs to degrade important target contaminants, such as 1,4-dioxane. Initial cost estimates indicate the UV/free chlorine AOP treatment to achieve 0.5-log 1,4-dioxane removal would be nearly half the cost for UV/H2O2 AOP. The cost for UV/chloramines AOP treatment could be comparable to UV/H2O2 AOP. Third, we demonstrated that after AOP treatment and chloramination for distribution systems, total halogenated DBP formation was comparable between these three AOPs. Chapter 5 summarizes the findings and contributions of this dissertation and proposes the issues that need to be addressed in future research to better understand the feasibility of these emerging AOPs in practice and to enable scale-up.

Download or read book TREATMENT OF CONTAMINANTS OF EMERGING CONCERN BY ADVANCED OXIDATION PROCESSES AND REVERSE OSMOSIS written by Djordje Vilimanovic and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discussion about contaminants of emerging concern (CECs) is now more prevalent than ever with the ever-increasing topic of non-potable and potable water reuse, especially with direct potable reuse. In the past and today, discharging CECs into an environmental buffer without complete removal is common practice. The Southern and Southwestern United States have been experiencing megadroughts and water shortages and have seen one of the biggest increases in population growth, and these factors put an additional strain on the water demand. Coupled with large, urbanized areas with increased life expectancy (aging population) only contributes to the rise of CECs in the wastewater treatment plants (WWTP) and, subsequently, the surface waters. The CECs previously discharged into the environment can no longer be ignored.This first part of this dissertation was carried out to increase our understanding of the concentration, distribution, occurrence, and potential risk of personal care products (PPCPs) by sampling large and small tributaries of the Delaware River in Pennsylvania. PPCPs are one of the largest categories of CECs and require further investigation. Working from a previous multiyear study conducted by the Delaware River Basin Commission (DRBC) on the main stem of the Delaware River, fifteen compounds were selected based on their high frequency of detection. Ten sampling sites were chosen on tributaries receiving numerous municipal and industrial discharges. Sampling locations were above and below potential source discharges. Sampling was conducted in three different seasons to account for seasonal differences in CECs loadings. The measured environmental concentrations of the target compounds present an insight into the urban and industrial impacts on subwatershed receiving waters. An index for levels of concern (LOC) was applied to the sample locations by comparing measured environmental concentrations, existing target compound water quality criteria, predicted no effects levels, and developing a concern summary variable. All the PPCPs were detected at high frequencies. Triclocarban and diphenhydramine demonstrated to be compounds of high relative risk (RR) to the aquatic life of the Pennsylvania tributaries to the Delaware River. Metformin was labeled low concern but had the highest environmental concentrations and continual presence due to high loading. The second part of the work focused on an unorthodox approach to treating CECs. Advanced oxidation processes (AOPs), specifically ultraviolet (UV) light and hydrogen peroxide (UV/peroxide), were deployed as a pretreatment to the reverse osmosis (RO) feed. The use of AOPs with RO is commonly used in the treatment (polishing) of the permeate and the treatment of the concentrate. As per California's State Water Resources Control Board, one of the regulatory leaders in water reuse in the US, 1,4-dioxane was utilized as a benchmark to estimate the water reuse processes' efficiency with a minimum 0.5 log10 (69%) reduction. UV/peroxide showed to be an effective AOP in removing multiple CECs in a simulated RO feed. Based on the electric energy per order of removal (EE/O), pretreatment is four-fold more efficient than posttreatment. AdOxTM modeling software was utilized to estimate the treatment kinetics of the feed water and the concentrate. Pretreatment showed to be a viable, more efficient option for treating the CECs with RO compared to the post-treatment of the concentrate and the permeate.
