This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The increasingly more stringent regulations related to wastewater quality and the inability of conventional wastewater treatment to adequately eliminate contaminants of emerging concern (CECs) make it essential to develop novel treatment approaches to upgrade existing treatment train. Catalytic ozonation is one of the newest advanced oxidation processes (AOPs) investigated as a strategy to improve the quality of wastewater prior to discharge in the environment. The present Ph.D. thesis focused on expending the knowledge about catalytic ozonation and identify novel materials as efficient catalysts for CECs removal and wastewater disinfection. The results of this research are presented in two manuscripts. The first manuscript reports on the screening of the potential catalysts, on the apparent reaction kinetics, and on the reusability of the most promising catalysts. The screening was conducted in a semi-batch reactor in MilliQ water (MQW) and synthetic wastewater. TiO2/Al2O3, AL-1010S (Al2O3-based catalyst), and Polonite® were shown to enhance the efficiency of catalytic treatment for the CECs removal and disinfection of E. coli. The apparent kinetic reaction between oxidative species (ozone and hydroxyl radicals) and atrazine (ATZ) was studied in a batch reactor in MQW with the addition of scavengers. The reusability experiments demonstrated that TiO2/Al2O3 and AL-1010S maintained their efficiency over four consecutive days, with removal of ATZ at the level of more than 90% and disinfection efficiency exceeding the one obtained using non-catalytic ozonation by more than 1.5 MPN Log units. Polonite® provided the least stable efficiency as a function of time but provided significant increase in disinfection. The second manuscript reports on the effect of wastewater characteristics (chemical oxygen demand (COD) and nitrite (NO2) concentration) and operating conditions (ozone to catalysts ratio, ozone concentration, and hydraulic retention time (HRT)) on process efficiency using the two most promising materials identified, Polonite® and AL-1010S. The optimal parameters for disinfection and ATZ removal were defined to be 8 g-O3 nm3 of ozone gas concentration, 10 minutes of HRT and a ratio of 0.11 of ozone gas concentration to catalyst loading. Both NO2 and COD concentrations greatly impacted the efficiency of treatment but the use of AL-1010S or Polonite® rendered the process less sensitive to variations of these wastewater characteristics. The benefits of catalytic ozonation using AL-1010S or Polonite® were verified for the disinfection of effluent wastewaters collected from two municipal wastewater treatment plants but analytical challenges limited the information available to conclude on the potential for improved CEC removal." --

Book Synopsis Chemistry of Ozone in Water and Wastewater Treatment by : Clemens von Sonntag
Download or read book Chemistry of Ozone in Water and Wastewater Treatment written by Clemens von Sonntag and published by IWA Publishing. This book was released on 2012-08-31 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Even though ozone has been applied for a long time for disinfection and oxidation in water treatment, there is lack of critical information related to transformation of organic compounds. This has become more important in recent years, because there is considerable concern about the formation of potentially harmful degradation products as well as oxidation products from the reaction with the matrix components. In recent years, a wealth of information on the products that are formed has accumulated, and substantial progress in understanding mechanistic details of ozone reactions in aqueous solution has been made. Based on the latter, this may allow us to predict the products of as yet not studied systems and assist in evaluating toxic potentials in case certain classes are known to show such effects. Keeping this in mind, Chemistry of Ozone in Water and Wastewater Treatment: From Basic Principles to Applications discusses mechanistic details of ozone reactions as much as they are known to date and applies them to the large body of studies on micropollutant degradation (such as pharmaceuticals and endocrine disruptors) that is already available. Extensively quoting the literature and updating the available compilation of ozone rate constants gives the reader a text at hand on which his research can be based. Moreover, those that are responsible for planning or operation of ozonation steps in drinking water and wastewater treatment plants will find salient information in a compact form that otherwise is quite disperse. A critical compilation of rate constants for the various classes of compounds is given in each chapter, including all the recent publications. This is a very useful source of information for researchers and practitioners who need kinetic information on emerging contaminants. Furthermore, each chapter contains a large selection of examples of reaction mechanisms for the transformation of micropollutants such as pharmaceuticals, pesticides, fuel additives, solvents, taste and odor compounds, cyanotoxins.

Available in PDF, EPUB and Kindle. Book excerpt: Water is essential for life in all the levels: humans, animals and plants depend on it for their existence. The unsustainable growth, the changes in the consumption pattern and the climate change have positioned water resources under pressure. In this scenario where the water quality and quantity are a worldwide concern, research and development have analyzed and generated various emerging technologies that can promote the use of alternative sources of water. Commonly, the Municipal WWTPs are organized in four stages that include physical, chemical and biological processes. Wastewater treatment plants (WWTPs) will have an important role in the future eco-cities since will provide energy by means of a system characterized by the smallest possible ecological footprint. However, several ecological effects have been observed downstream of WWTP outfalls, probably due to the incomplete removal of pollutants by the conventional WWTPs. The analysis and understanding of the pollutants fate in Conventional WWTPs is fully necessary to create measures to reduce their release in the environment. Even though, conventional WWTPs are designed to treat solid wastes, suspended solids and biodegradable dEfOM, many micropollutants are also affected by the treatment train. Hence, half of the micropollutant load is eliminated either by sorption to the sludge, biological degradation, volatilization and abiotic degradation. Despite this fact, some hydrophilic compounds are neither adsorbed into the sludge nor eliminated in the discharge effluents. Consequently, some of these micropollutants can end up in the aquatic environment generating negative effects, including long-term and short-term toxicity. In the problematic water pollution scenario mentioned before, advanced oxidation processes (AOPs) emerge as a possible alternative to treat the biologically persistent wastewater improving water quality and therefore restoring the aquatic environment. These processes degrade organic pollutants by forming hydroxyl radicals (OH·) which are highly reactive and non- selective. Nowadays, AOPs include also the processes that involve other radicals as sulfate radicals (SO4 ·). Ozone application is used in wastewater, disinfection and air treatment to minimize the pollution. This process has two main strengths: on one hand, the strong oxidant potential and secondly, the lack of residues after its application. Ozone can react directly, via molecular pathway or indirectly via hydroxyl radical. In this work, ozone has been applied to different non-conventional points of the treatment line, to check if its action could promote the enhancement of the whole treatment. Thus, it has been applied at the outlet of the primary effluent leading us to an improvement in the water quality parameters and in the removal of micropollutants. Moreover, other significant parameters for ozone application as the ozone demand and mass transfer have been studied. Afterwards, the study was focus in the application of ozone on the activated sludge matrix. In this case, ozone showed good performance too, improving the settleability, increasing the solubility of sludge and eliminating micropollutants in both phases (sludge and supernatant). Finally, the combination of ozone application with biological treatments was tested. Thus, ozone was applied to the primary effluent which was lately treated by an aerobic biological treatment. In this case, good performances were observed at the level of micropollutants. Lately, ozone was applied to the conventional activated sludge matrix which was subsequently introduced in an anaerobic process to check the enhancement of biogas production. In this case, only two ozone doses showed better performances than the initial sludge without ozone pretreatment. Biodegradability and acute toxicity was studied for the primary effluent before and after ozonation, showing an improvement when the transfer ozone dose increased.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent decades, scientific insight into the chemistry of water has increased enormously, leading to the development of advanced wastewater and water purification technologies. However, the quality of freshwater resources has continually deteriorated worldwide, both in industrialized countries and in developing countries. Although traditional wastewater technologies are focused on the removal of suspended solids, nutrients and bacteria, hundreds of organic pollutants occur in wastewater and affected urban surface waters. These new pollutants are synthetic or naturally occurring chemicals that are not often monitored in the environment but have the potential to penetrate the environment and cause known or suspected adverse ecological and/or human health effects. These contaminants are collectively referred to as the "Emerging Contaminants" and are mostly derived from domestic use and occur in trace concentrations ranging from pico to micrograms per litre. Environmental contaminants are recalcitrant for conventional wastewater treatment processes and most of them remain unaffected, leading to the contamination of receiving water. This scenario leads to the need for an advanced wastewater treatment process that can remove environmental contaminants to safely monitor fresh water sources. This book explains the technologies of biological and chemical wastewater treatment processes. The biological wastewater treatment processes presented include: (1) bioremediation of wastewater that includes aerobic treatment (oxidation ponds, aerating lagoons, aerobic bioreactors, active sludge, percolation or drip filters, biological filters, rotating biological contactors, biological removal of nutrients) and anaerobic treatment (anaerobic bioreactors), anaerobic lagoons); (2) phytoremediation of waste water consisting of engineered wetlands, rhizofiltration, rhizodegradation, phytodegradation, phytoaccumulation, Phyto transformation and hyperaccumulators; and (3) mycoremediation of wastewater. The chemical wastewater treatment processes discussed include chemical precipitation (coagulation, flocculation), ion exchange, neutralization, adsorption, and disinfection (chlorination / dechlorination, ozone, UV light). In addition, this chapter explains the wastewater treatment plants and illustrates them in terms of plant size, plant layout, and plant design and installation location.

Available in PDF, EPUB and Kindle. Book excerpt: The ozonation of compounds in water is a complex process. The mechanisms are very complicated, the parameters are many, but the possibilities of developing cost-effective treatment schemes for drinking water and waste water are large. Most books available today concentrate on either drinking water or waste water treatment, seldom dealing with both or explaining the essential differences. And only rare exceptions deal with the how-to of ozone experiments. This practical guide fills the gap. It contains the cumulative knowledge on experimental design, execution, interpretation and application. Drawing on experience gained from hours spent on laboratory research with drinking and waste waters, literature study, intensive discussion with leading experts, perplexed reflection and deep thought, the book offers practical help to avoid common pitfalls and unnecessary work. This book is aimed at professionals in industry and research currently using ozonation who want to optimize their system, as well as students beginning work with ozonation. It contains just enough information for beginners to start with, but goes rapidly to the detailed information that advanced readers need.
