Download or read book Micropollutants in wastewater in four arctic cities written by Maria Dam and published by Nordic Council of Ministers. This book was released on 2017-12-18 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: The four Nordic cities included in the present study form a gradient both in climate, from oceanographic temperate in Tórshavn at 620 N to arctic in Tromsø at 69.70N, and in population, from less than 6000 inhabitants in Sisimiut to close to 120 000 in Reykjavík. The cities are different and far apart but products from the sea has been mainstay to the economy and societal development. Thus, the management of sewage from the municipalities must maintain a clean and healthy marine environment. The wastewater treatment varies, from screening on fine mesh, via septic tank based purification solutions, to no purification at all. We measured the contaminants in wastewater streams and in recipient samples, and with that in hand assessed whether the wastewater treatment appeared sufficient, and if not, which mitigating solutions could be relevant for wastewater purification optimisation.
Download or read book Improved Sorptive Removal of Polar Organic Micropollutants from Water Using Surface Modified and Polarized Activated Carbons written by Jieying Zhou and published by . This book was released on 2022 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Emerging organic persistent and mobile (PM) micropollutants can survive the conventional water treatment barriers and end up as hazards in drinking water. Activated carbon (AC) adsorption is one of the prevailing strategies in modern wastewater treatment facilities, which shows satisfying removal ability for non-polar organic compounds, yet not for many highly hydrophilic PM substances. Knowledge in the adsorption drivers for traditional nonpolar organic micropollutants urgently needs to be updated for polar neutral, ionizable andionic compounds taking into account the additional adsorbent/adsorbate interactions. In the scale of this dissertation, we investigated the effect of surface chemical modification (i.e. surface defunctionalization and surface oxidation) and electric polarization of AC felts on the adsorption behaviors of seven environmentally relevant PM contaminants representing polar neutral, cationic and anionic compounds. Surface defunctionalization was found to provide a universal strategy to improve the AC adsorption efficiency for all probed PM types while additional electric polarization can further broaden the flexibility in regulating the uptake and release of charged PM compounds. The electro-assisted ad-/desorption of PM molecules with promising enrichment effects estimated from the batch and flow experiments as well as long-term stability (>20 days, 5 cycles) was proven, which proposes a facile, green, in-situ AC regeneration compared to the state-of-the-art off-site hightemperature regeneration approach. Moreover, we showcased a membrane-free, singlechannel flow unit using two AC electrodes carrying different surface chemistries for an effective removal of highly polar trifluoroacetate from tap water. Our findings shall inspire the next-generation design of adsorbent materials and (electro-)sorptive processes to treat water contaminated by emerging PM substances.

This book was released on 2017-06-15 with total page 690 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the 3R concept applied to wastewater treatment and resource recovery under a double perspective. Firstly, it deals with innovative technologies leading to: Reducing energy requirements, space and impacts; Reusing water and sludge of sufficient quality; and Recovering resources such as energy, nutrients, metals and chemicals, including biopolymers. Besides targeting effective C,N&P removal, other issues such as organic micropollutants, gases and odours emissions are considered. Most of the technologies analysed have been tested at pilot- or at full-scale. Tools and methods for their Economic, Environmental, Legal and Social impact assessment are described. The 3R concept is also applied to Innovative Processes design, considering different levels of innovation: Retrofitting, where novel units are included in more conventional processes; Re-Thinking, which implies a substantial flowsheet modification; and Re-Imagining, with completely new conceptions. Tools are presented for Modelling, Optimising and Selecting the most suitable plant layout for each particular scenario from a holistic technical, economic and environmental point of view.
Download or read book Human Pharmaceuticals Hormones and Fragrances written by Thomas Ternes and published by IWA Publishing. This book was released on 2007-01-30 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: The observed concentrations of pharmaceuticals and personal care products (PPCPs) in raw wastewater confirm that municipal wastewater represents the main disposal pathway for the PPCPs consumed in households, hospitals and industry. In sewage treatment plant effluents most PPCPs are still present, since many of these polar and persistent compounds are being removed only partially or, in some cases, not at all. Treated wastewater therefore represents an important point source for PPCPs into the environment. After passing a sewage treatment plant the treated wastewater is mostly discharged into rivers and streams or sometimes used to irrigate fields. If drinking water is produced using resources containing a substantial proportion of treated wastewater (e.g. from river water downstream of communities) the water cycle is closed and indirect potable reuse occurs. Human Pharmaceuticals, Hormones and Fragrances provides an overview of the occurrence, analytics, removal and environmental risk of pharmaceuticals and personal care products in wastewater, surface water and drinking water. The book covers all aspects of the fate and removal of PPCPs in the whole water cycle: consumption and occurrence, analytical methods, the legal background, environmental risk assessment, human and animal toxicology, source control options, wastewater and drinking water treatment as well as indirect reuse. The book presents a summary of the results obtained during the EU project "Poseidon", combined with further expert knowledge on the field, and is written at a level appropriate for professionals involved in management of water resource quality. Professionals in the field including decision makers, engineers and scientists, as well as students entering the field, will find this an invaluable source of information. First comprehensive study on the assessment, fate and removal of pharmaceuticals and personal care products in wastewater and drinking water treatment. Emphasises the importance of micropollutants in the water cycle, provides methods for quantifying their fate and technologies for their removal.

Download or read book Treatment of Micropollutants in Water and Wastewater written by Jurate Virkutyte and published by IWA Publishing. This book was released on 2010-08-14 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last few years there has been a growing concern over the increasing concentration of micropollutants originating from a great variety of sources including pharmaceutical, chemical engineering and personal care product industries in rivers, lakes, soil and groundwater. As most of the micropollutants are polar and persistent compounds, they are only partially or not at all removed from wastewater and thus can enter the environment posing a great risk to the biota. It is hypothesized that wastewater is one of the most important point sources for micropollutants. Treatment of Micropollutants in Water and Wastewater gives a comprehensive overview of modern analytical methods and will summarize novel single and hybrid methods to remove continuously emerging contaminants - micropollutants from the aqueous phase. New trends (e.g. sensor technology, nanotechnology and hybrid treatment technologies) are described in detail. The book is very timely because the new techniques are still in the development phase and have to be realized not only in the laboratory but also on a larger scale. The content of the book is divided into chapters that present current descriptive and analytical methods that are available to detect and measure micropollutants together with detailed information on various chemical, biological and physicochemical methods that have evolved over the last few decades. Treatment of Micropollutants in Water and Wastewater will also enable readers to make well informed choices through providing an understanding of why and how micropollutants must be removed from water sources, and what are the most appropriate and available techniques for providing a cost and technologically effective and sustainable solutions for reaching the goal of micropollutant-free water and wastewater. The book will be suitable for water and wastewater professionals as well for students and researchers in civil engineering, environmental engineering and process engineering fields.

Download or read book Benzotriazole and Sulfamethoxazole written by Bastian Herzog and published by Sudwestdeutscher Verlag Fur Hochschulschriften AG. This book was released on 2014-03-31 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The xenobiotic micropollutants benzotriazole (BT) and the antibiotic sulfamethoxazole (SMX) are almost omnipresent in aquatic systems, including drinking water. Thus, the question how to cope with these problems, arises. Therefore, this study evaluates the potential of activated sludge communities (ASCs) and pure cultures to biodegrade three different BTs and SMX. Firstly, wastewater treatment plants were monitored for their BTs removal efficiency. Subsequently, laboratory setups, performed with a cost-efficient UV-absorbance-based measurement system, were established. The results showed that two BTs were aerobically biodegraded in ASCs but not under denitrifying or anaerobic conditions, while one was biologically stable. Additional experiments showed nutrients, especially nitrogen, as well as acclimation to be crucial for biodegradation. Finally, a metagenomic analysis of the ASC revealed four dominant species. To evaluate SMX biodegradation, nine different bacteria species were isolated from ASCs and were incubated in different media containing 10 mg L-1 SMX. The species revealed high biodegradation rates being dependent on carbon and nitrogen concentrations.

Download or read book Security of Public Water Supplies written by Rolf A. Deininger and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The best of all things is water" -Pindar 460 B. C. The provision of secure drinking water for its citizens is an aim of every government, and is a priority item to all the NATO and CP countries. The quantity of water in most of these countries is usually adequate, but the quality in many cases is not. With the development of new analytical methods, one suddenly finds new substances of human origin in drinking water. Also, new microorganisms and their toxins pass through the conventional treatment plants to show up in the finished water. What aU of this means to public health is not quite clear at the moment, but it seems that increased vigilance is necessary to provide safe drinking water to all citizens. The NATO Advanced Research Workshop was organized to focus on five major areas of concern: • Inorganic contaminants, focusing on arsenic and copper • Organic contaminants, focusing on petroleum products, and insecticides and pesticides • Biological/bacteriological problems in raw water, finished water, and in the distribution system • River water watch and surveillance systems • The role of research, the economics of privatization, the support of international organizations This volume presents the papers that were delivered at the workshop over a period of four and one-half days. The workshop was attended by over 40 scientists, government officials, and academics from 20 NATO and CP countries.
Download or read book Passive Sampling Techniques in Environmental Monitoring written by Richard Greenwood and published by Elsevier. This book was released on 2007-07-03 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monitoring pollutants in air, soil and water is a routine requirement in the workplace, and in the wider environment. Passive samplers can provide a representative picture of levels of pollutants over a period of time from days to months by measuring the average concentrations to which they have been exposed. Air monitors are widely used, for instance to measure the exposure of workers to volatile compounds, but also for monitoring the fate of pollutants in the atmosphere. Passive sampling devices are now becomining increasingly used to monitor pollutants in rivers, coastal waters and ground water where contamination results from sources such as domestic and industrial discharges, and the use of agrochemicals. Passive Sampling Techniques in Environmental Monitoring provides a timely collection of information on a set of techniques that help monitor the quality of air, surface and ground waters. Passive sampling can provide an inexpensive means of obtaining a representative picture of quality over a period of time, even where levels of pollutants fluctuate due to discontinuous discharges or seasonal application of chemicals such as pesticides. Recent changes in legislation have increased the pressure to obtain better information than that provided by classical infrequent spot sampling.Brought together in one source, this book looks at the performance of a range of devices for the passive sampling of metals, and of non-polar and polar organic chemicals in air and in water. The strengths and weaknesses and the range of applicability of the technology are considered.* Comprehensive review of passive sampling - covering air, water and majority of available technologies in one volume* Chapters written by international specialist experts * Covers theory and applications, providing background information and guidelines for use in the field
