Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this project was to perform a careful evaluation of the technical and economic feasibility of advanced oxidation processes (AOPs) for methyl tertiary butyl ether (MTBE) removal. Specifically, the first objective of this project was to identify and fill data gaps related to the implementation and operation of AOPs with respect to MTBE removal. The second objective was to select and optimize the design of the most promising AOP(s) as a function of water quality parameters. The third objective was to determine conceptual-level engineering costs for these selected AOPs. The AOP technologies that were evaluated as part of this study included ozone/peroxide, continuous wave UV/peroxide, pulsed UV/peroxide, and E beam. The AOP technologies were compared with treatment costs, qualitative factors (e.g., technology reliability, flexibility), and influent and treated water quality considerations. Based on the comparative analysis, it was concluded that all the AOP technologies that were evaluated in this study are capable of removing MTBE at 95% or higher efficiencies. Ozone/peroxide and continuous UV/peroxide appear to be the most feasible technologies for AOP treatment of MTBE in drinking water sources. Originally published by AwwaRF for its subscribers in 2003

Available in PDF, EPUB and Kindle. Book excerpt: The widespread use of the fuel oxygenate methyl tert-butyl ether (MTBE) has led to the contamination of both surface and groundwater supplies. This study evaluates the treatment of MTBE contaminated drinking water using air stripping and advanced oxidation processes (AOPs) on a pilot scale. The treatment efficiency of the air stripper was evaluated at different air/water ratios ranging from 105:1 to 206:1. Although a treatment efficiency of>99% was achieved for each of the air/water ratio studied, the depth of the packing required to achieve this efficiency increased with decreasing air/water ratio. The adsorption studies conducted on MTBE laden off-gas from the air stripper showed that granular activated carbon (GAC) has a higher adsorptive capacity than the carbonaceous polymeric resin. Experiments conducted at different off-gas relative humidity (RH) of 20%, 30% and 50% reveal that the GAC adsorptive capacity decreased with increasing RH, whereas, the RH did not impact the resin adsorptive capacity. Ozone/hydrogen peroxide (O3/H2O2), ozone/UV (O3/UV), hydrogen peroxide/UV (H2O2/UV), and ozone/hydrogen peroxide/UV (O3/H2O2/UV) are the four AOPs evaluated in this study. An increase in the recycle ratio by 100% resulted in a 5% increase in the treatment efficiency. A treatment effectiveness of 98% was achieved with the use of O3/UV process at an O3 concentration of 5.8 mg/L. The experimental results have shown that the O3/H2O2 process is a slightly more effective (2 to 3% more) treatment process than the O3/UV process at the same O3 concentrations and a H2O2:O3 molar ratio of 1.4:1. Increased treatment efficiencies were observed with increasing H2O2:O3 molar ratios, with the optimum ratio for maximum treatment efficiency being 1:1. Non-detectable levels of MTBE were recorded in the O3/H2O2/UV process, at an O3 dosage of 5.8 mg/L and a H2O2:O3 molar ratio of 1.4:1. The O3/H2O2/UV process was more effective than the O3/H2O2 process at lower H2O2:O3 molar ratios and at ratios above 1:1, the difference in the treatment efficiencies was negligible. Tert-butyl formate, tert-butyl alcohol), methyl acetate and acetone were the major oxidation by-products identified in all the AOPS. The conducted cost analyses revealed that air stripping was the most cost effective treatment process compared to the AOPs.

Download or read book Advanced Oxidation Processes for Water and Wastewater Treatment written by Simon Parsons and published by IWA Publishing. This book was released on 2004-03-01 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: The suitability of Advanced Oxidation Processes (AOPs) for pollutant degradation was recognised in the early 1970s and much research and development work has been undertaken to commercialise some of these processes. AOPs have shown great potential in treating pollutants at both low and high concentrations and have found applications as diverse as ground water treatment, municipal wastewater sludge destruction and VOCs control. Advanced Oxidation Processes for Water and Wastewater Treatment is an overview of the advanced oxidation processes currently used or proposed for the remediation of water, wastewater, odours and sludge. The book contains two opening chapters which present introductions to advanced oxidation processes and a background to UV photolysis, seven chapters focusing on individual advanced oxidation processes and, finally, three chapters concentrating on selected applications of advanced oxidation processes. Advanced Oxidation Processes for Water and Wastewater Treatment will be invaluable to readers interested in water and wastewater treatment processes, including professionals and suppliers, as well as students and academics studying in this area. Dr Simon Parsons is a Senior Lecturer in Water Sciences at Cranfield University with ten years' experience of industrial and academic research and development.

This book was released on 2010 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Treatment of Methyl Tert-Butyl Ether (MTBE) from wastewater supplies presents specific challenges due to the physicochemical properties of MTBE which depend strongly on its hydrophilic nature, and translate into a high solubility in water. MTBE has very low Henry's constant and very low affinity for common adsorbents. An investigation was carried out for the treatability of metyl tert-butyl ether (MTBE) in synthetic wastewater. In this research, experimental rig and benchscale studies using granular activated carbon (GAC) and hydrogen peroxide (H2O) were conducted to observe the treatability of MTBE in synthetic wastewater. An experimental rig was built up that consist of three conjugated system. Subsequently, MTBE was amended to the H2O22 and air flow, followed by adsorption treatment with GAC. Generally, the major finding suggests that the longer cycle pulsation time (3 minutes open valve + 5 seconds closed valve) with air flow rate at 6 L/min over the synthetic wastewater caused a greater removal of MTBE. The result of this study can help to provide specific guidance into process parameter selection for treating MTBE in wastewaters. The optimum operating conditions are very important for treating the wastewater effectively in a larger scale.

Book excerpt: This project studies the application of high-silica zeolites for the removal of polar organic contaminants, i.e., antimicrobial compounds and the fuel additive methyl tertiary-butyl ether (MTBE), from drinking water. Recently published data show that high-silica zeolites, a class of crystalline adsorbents with well defined pore sizes, exhibit considerably larger single-solute MTBE adsorption capacities than activated carbons and carbonaceous resins. The effectiveness of high-silica zeolites is compared to that of activated carbons and a carbonaceous resin.
