Abstract:

This thesis explores various novel ways of treatment of wastewater contaminated by toxic organic pollutants using single and combined advanced oxidative wastewater treatment technologies in conjunction with a variety of acoustic and hydrodynamic cavitational reactors. There have been many reports in the literature on the use of hydroxyl radicals as the core part of AOPs and hence, as the first objective, the amount of hydroxyl radical generation from different acoustic and hydrodynamic cavitational reactors was studied using the potassium iodide dosimeter. The results reveal that optimum conce

Abstract:

A large variety of disinfection by-products (DBPs) are formed during water treatment processes using chlorination. Disinfection with chloramines is often used to significantly reduce the formation of regulated DBPs. However, chloramination favours the formation of N-nitrosamines, which are emerging by-products of health concern. Of all the nitrosamines, N-nitrosodimethylamine (NDMA) has been most commonly detected in drinking water and wastewater. Nitrosamines can also be produced using different disinfectants, including chlorine dioxide and ozone. Wastewater often contains considerable concen

Aquesta tesi s'emmarca dins de dos projectes relacionats amb la recuperació (tractament + reutilització) d'aigües residuals generades per la indústria de petroli i gas. L'objectiu del primer projecte va ser la reutilització d'aigua residual generada per aquest sector mitjançant el tractament dels anomenats efluents "downstream" amb processos d'oxidació avançats (AOPs). Amb aquest objectu, es van estudiar diversos processos AOPs fotocatalítics i basats en ozó, els quals es van aplicar, en primer lloc, per al tractament d'una aigua sintètica amb una composició complexa representativa d'aigua res

Abstract:

The presence of several pharmaceutical active compounds (PhACs) in water bodies has garnered increasing attention and worldwide concern. The effluents from wastewater treatment plants (WWTPs) are one of the main sources of PhACs in aquatic environments. Advanced tertiary treatments are required to improve the quality of WWTP effluents discharged into sensitive receiving water bodies. This thesis has focused on biological activated carbon coupled with ultrafiltration (BAC-UF) and UV-C activated peroxydisulfate and peroxymonosulfate (UV/PDS and UV/PMS). The BAC-UF technology has been evaluated a

Abstract:

Os resíduos sólidos da indústria coureira são produzidos em diferentes etapas de limpeza, classificação e ajuste da espessura do couro, e são classificados como perigosos quando gerados nas etapas posteriores ao curtimento com cromo. Os resíduos que já passaram pela etapa de curtimento apresentam elevada estabilidade, não sendo facilmente degradados. Além disso, nas etapas do acabamento molhado do couro, em especial no tingimento, corantes são utilizados para conferir cor aos artigos. Devido à necessidade de utilização de água e corantes em excesso, são gerados, nessas etapas, efluentes colori

Abstract:

This thesis deals with advanced oxidation processes (AOPs) and it’s use for removal of micropollutants from wastewater. The first chapter explains the need AOPs, water quality, pollution and substances that are present in the water. Further, the first chapter outlines approach of the current legislation to micropollutants. The second chapter explains the theory and principle of operation of AOPs. This chapter is divided into two sections. The first section describes AOPs, which were tested at selected WWTP. In the second section, there are described some other AOPs. The third chapter is a lite

La pollution des ressources en eau est un des défis importants auquel les Hommes doivent faire face. En particulier, de nouvelles solutions doivent émerger, puisque les techniques conventionnelles de traitement utilisées actuellement ne permettent pas une élimination efficace des divers polluants. Parmi les polluants émergents, les composés pharmaceutiques ont récemment été détectés dans différentes sources d'eau à travers le monde. Leurs effets indésirables sur l'environnement naturel et sur l'Homme ont déjà été reconnus mais doivent encore être éclaircis. De nombreux nouveaux procédés de tra

Abstract:

L'adsorption sur charbon actif est une technique relativement répandue de post-traitement des effluents aqueux. Cependant il ne s'agit pas d'un traitement ultime, puisque les polluants restent concentrés sur la surface solide. Des techniques de régénération doivent donc être mises en œuvre. C'est dans ce contexte qu'ont été étudiés ici les procédés d'oxydation avancée Fenton et photo-Fenton, dont l'efficacité est reconnue pour éliminer la pollution organique. Plus précisément, l'objet de cette thèse est l'étude sur plusieurs cycles consécutifs de l'adsorption du phénol sur charbon actif et de
