Enhanced Biological Phosphorus Removal - Laurens Welles - Bog - Taylor & Francis Ltd - Plusbog.dk

Enhanced Biological Phosphorus Removal - Laurens Welles - Bog - Taylor & Francis Ltd - Plusbog.dk

The Enhanced Biological Phosphorus Removal (EBPR) process is a biological process for efficient phosphate removal from wastewaters through intracellular storage of polyphosphate by Phosphate-Accumulating Organisms (PAO) and subsequent removal through wastage of excess sludge. Although many studies have demonstrated the existence of different PAO clades, the functional differences among these clades and potential implications for the process performance remained unclear. Furthermore, the salinity effects on the EBPR process had not been properly investigated, which is necessary to assess its applicability for the treatment of saline wastewaters. The first part of the thesis focuses on the functional diversity among PAO clades. It demonstrates significant functional differences in the main characteristics of the anaerobic metabolism of two different PAO clades and provides fundamental insight in the metabolic response of PAO to different influent P/C ratios. In addition, it shows how these functional differences provide competitive advantages to specific PAO clades in a selection study and discusses their potential implications on process performance, in particular for combined biological and chemical systems for nutrient removal and recovery. The second part of the thesis describes the salinity effects on the metabolism of PAO and their competitors that do not contribute to phosphorus removal; the so-called Glycogen-Accumulating Organisms (GAO). It shows how salinity affects the different metabolic processes (kinetics and stochiometry) of PAO and GAO and provides a model that describes the salinity effects on their kinetic rates. Finally, it discusses the potential implications of sudden saline shocks in wastewater treatment systems that are not regularly exposed to salinity.

The Age of Mass Child Removal in Spain - Peter (associate Professor In Twentieth Century European History Anderson - Bog - Oxford University Press -

The Age of Mass Child Removal in Spain - Peter (associate Professor In Twentieth Century European History Anderson - Bog - Oxford University Press -

The Age of Mass Child Removal in Spain analyses the ideas and practices that underpinned the age of mass child removal. This era emerged from growing criticisms across the world of ''dangerous'' parents and the developing belief in the nineteenth century that the state could provide superior guardianship to ''unfit'' parents. In the late nineteenth century, the juvenile-court movement led the way in forging a new and more efficient system of child removal that severely curtailed the previously highly protected sovereignty of guardians deemed dangerous. This transnational movement rapidly established courts across the world and used them to train the personnel and create the systems that frequently lay behind mass child removal. Spaniards formed a significant part of this transnational movement and the country''s juvenile courts became involved in the three main areas of removal that characterize the age: the taking of children from poor families, from families displaced by war, and from political opponents. The study of Spanish case files reveals much about how the removal process worked in practice across time and across democratic regimes and dictatorships. These cases also afford an insight into the rich array of child-removal practices that lay between the poles of coercion and victimhood. Accordingly, the study offers a history of some of most marginalized parents and children and recaptures their voice, agency, and experience. Peter Anderson also analyses the removal of tens of thousands of children from General Franco''s political opponents, sometimes referred to as the lost children of Francoism, through the history and practice of the juvenile courts.

Manganese Removal from Groundwater - J.h. Bruins - Bog - Taylor & Francis Ltd - Plusbog.dk

Manganese Removal from Groundwater - J.h. Bruins - Bog - Taylor & Francis Ltd - Plusbog.dk

In The Netherlands, Belgium and other European countries, manganese is removed by conventional groundwater treatment with aeration and rapid (sand) filtration. Such a treatment process is easy to operate, cost effective and sustainable, because it does not make use of strong oxidants such as O 3 , Cl 2 , ClO 2 and KMnO 4 with the associated risk of by-product formation and over or under dosing. However, application of aeration-filtration is also facing drawbacks, especially the long ripening time of filter media. Due to the long ripening time, water companies have to waste large volumes of treated water, making this process less sustainable. Also, costs associated with filter media ripening (man power, electricity, operational and analysis costs) are high. Therefore decreasing the filter ripening time, regarding manganese removal is a big issue. Although already extended research has been carried out into manganese removal, the controlling mechanisms, especially of the start up face of filter media ripening, are not fully understood yet. The emphasis of this thesis is to provide a better understanding of the mechanisms involved in the ripening of virgin filter media, regarding manganese removal and how to shorten or completely eliminate the long ripening period of filters with virgin material. This thesis therefore highlights the role of the formation of a manganese oxide coating on virgin filter media. Characterization and identification revealed that the responsible manganese oxide for an effective manganese removal was Birnessite. It was found that Birnessite, formed at the beginning of the ripening process was of a biological origin. Based on the knowledge that manganese removal in conventional groundwater treatment is initiated biologically, long ripening times may be reduced by creating conditions favouring the growth of manganese oxidizing bacteria, e.g., by limiting the back wash frequency and / or intensity. Additionally, this thesis also shows that the use of freshly prepared manganese oxide, containing Birnessite, can completely eliminate filter media ripening time.

Photo-Activated Sludge: A Novel Algal-Bacterial Biotreatment for Nitrogen Removal from Wastewater - Angelica Rada Ariza - Bog - Taylor & Francis Ltd -

Photo-Activated Sludge: A Novel Algal-Bacterial Biotreatment for Nitrogen Removal from Wastewater - Angelica Rada Ariza - Bog - Taylor & Francis Ltd -

Nitrogen rich wastewaters (10-400 mg N L -1 ) are usually produced by municipal, industrial and agricultural wastes, such as effluents from anaerobic treatments. These represent a risk to the environment due to the high nutrient concentrations (nitrogen and phosphorous), which can cause eutrophication of water bodies, deteriorating the quality of the ecosystems. As a solution, the potential nitrogen removal capacity of a novel bio-treatment system, namely the Photo-Activated Sludge (PAS), which is composed of microalgae and bacteria consortia, is presented in this thesis. This novel bio-treatment is based on the symbiosis between microalgae, nitrifiers and heterotrophic bacteria (microalgal-bacterial consortia). Experimental work using photobioreactors for the cultivation of microalgae and bacteria under sequencing batch conditions showed that microalgal-bacterial consortia can remove ammonium 50% faster than solely microalgal consortia. The increase in ammonium removal rates was due to the action of nitrifying bacteria, supplied with oxygen produced by algae. Nitrification was the main ammonium removal mechanism within the microalgal-bacterial biomass, followed by algal uptake and nutrient requirements for bacterial growth. Carbon oxidation and denitrification were the main removal mechanisms for organic carbon. Hence, the role of algae within the microalgal-bacterial system is to provide oxygen to support the aerobic processes. The microalgal-bacterial system offers the possibility of reducing the hydraulic retention time, which can decrease the large area requirements often demanded by algal systems.

Anaerobic Treatment of Mine Wastewater for the Removal of Selenate and its Co-Contaminants - Lea Chua (unesco Ihe Institute For Water Education Tan -

Anaerobic Treatment of Mine Wastewater for the Removal of Selenate and its Co-Contaminants - Lea Chua (unesco Ihe Institute For Water Education Tan -

Selenium (Se) pollution has led to several cases of severe aquatic ecosystem deterioration due to Se poisoning caused by bioaccumulation over time. However, the removal of selenate (SeO 4 2- ) from wastewater streams with co-contaminants has been largely considered as a black box in anaerobic biological systems using mixed consortia. This research aimed at addressing the effect of wastewater characteristics, i.e. co-contaminants such as nitrate (NO 3 - ) and sulfate (SO 4 2- ), heavy metals and pH, on the biological reduction of SeO 4 2- and evaluating process integration for Se-laden wastewater treatment with co-contaminants. This study demonstrated that the presence of co-contaminants can actually be beneficial for Se removal provided that the concentrations are carefully monitored and appropriate operating conditions and process configurations are used. The Se removal (total Se and SeO 4 2- ) efficiency increased by ~30% in the presence of NO 3 - and/or SO 4 2- compared to systems with SeO 4 2- alone. Additionally, an integrated process of an ion exchange (IX) column and bioreactors showed improved overall removal capacity for SO 4 2- and total Se. The knowledge and information gained from this research can help in the advancement and application of biological processes, i.e. predicting of reactor performance, solving specific design or practical problems and implementing novel treatment techniques for Se-laden mine wastewater.

Effect of Sulphide on Enhanced Biological Phosphorus Removal - Francisco Rubio Rincon - Bog - Taylor & Francis Ltd - Plusbog.dk

Effect of Sulphide on Enhanced Biological Phosphorus Removal - Francisco Rubio Rincon - Bog - Taylor & Francis Ltd - Plusbog.dk

The enhanced biological removal of phosphorus (EBPR) is a popular process due to high removal efficiency, low operational costs, and the possibility of phosphorus recovery. Nevertheless, the stability of the EBPR depends on different factors such as: temperature, pH, and the presence of toxic compounds. While extensive studies have researched the effects of temperature and pH on EBPR systems, little is known about the effects of different toxic compounds on EBPR. For example, sulphide has shown to inhibit different microbial activities in the WWTP, but the knowledge about its effects on EBPR is limited. Whereas the sulphide generated in the sewage can cause a shock effect on EBPR, the continuously exposure to sulphide potentially generated in WWTP can cause the acclimatization and adaptation of the biomass. This research suggests that sulphate reducing bacteria can proliferate in WWTP, as they are reversibly inhibited by the recirculation of sludge through anaerobic-anoxic-oxic conditions. The research enhances the understanding of the effect of sulphide on the anaerobic-oxic metabolism of PAO. It suggests that the filamentous bacteria Thiothrix caldifontis could play an important role in the biological removal of phosphorus. It questions the ability of PAO to generate energy from nitrate respiration and its use for the anoxic phosphorus uptake. Thus, the results obtained in this research can be used to understand the stability of the EBPR process under anaerobic-anoxic-oxic conditions, especially when exposed to the presence of sulphide.

Pesticide Removal by Combined Ozonation and Granular Activated Carbon Filtration - Ervin Orlandini - Bog - A A Balkema Publishers - Plusbog.dk

Pesticide Removal by Combined Ozonation and Granular Activated Carbon Filtration - Ervin Orlandini - Bog - A A Balkema Publishers - Plusbog.dk

This research aimed to identify and understand mechanisms thar underlie the beneficial effect of ozonation on removal of pesticides and other micropollutants by Granular Activated Carbon (GAC) filtration. This allows optimization of the combination of these two processes, termed Biological Activated Carbon filtration. The study concluded that ozonation significantly improves removal of atrazine by GAC filtration not only due to the wellknown effect of oxidation of atrazine, but also due to the effect of partical oxidation of Background Organic Matter (BOM) present in water. Ozone-induced oxidation of BOM was found to improve adsorption of atrazine in GAC filters. Biodegradation of atrazine in these filters wasnot demonstrated. Higher GAC''s adsorption capacity for atrazine and faster atrazine''s mass transfer in filters with ozonated rather than non-ozonated influent were explained as due to ozonated BOM. Both can be attributed to enhanced biodegradability and reduced adsorbsbility of partially ozidated BOM compounds, resulting in their increased biodegradation and decreased adsorption in GAC filters.

American Indians and the Rhetoric of Removal and Allotment - Jason Edward Black - Bog - University Press of Mississippi - Plusbog.dk

American Indians and the Rhetoric of Removal and Allotment - Jason Edward Black - Bog - University Press of Mississippi - Plusbog.dk

Jason Black examines the ways the U.S. government''s rhetoric and American Indian voices contributed to the policies of Native-U.S. relations throughout the nineteenth century''s removal and allotment eras. Black shows how these discourses co-constructed the perception of the U.S. government and American Indian communities and contributed to the relationship. Such interactions - though certainly not equal between the two - illustrated the hybrid nature of Native-U.S. rhetoric in the nineteenth century. That is, both governmental colonizing discourse and indigenous decolonizing discourse added arguments, identity constructions, and rhetorical moves to the colonizing relationship.Native Dualities demonstrates how American Indians decolonized dominant rhetoric in terms of impeding the removal and allotment policies. By turning around the U.S. government''s discursive frameworks and inventing their own rhetorical tactics, American Indian communities helped restyle their own and the government''s identities. During the first third of the twentieth century, Native decolonization impacted the Native-U.S. relationship as American Indians urged for the successful passage of the Indian Citizenship Act of 1924 and the Indian New Deal of 1934. In the end, Native communities were granted increased rhetorical power through decolonization, though the U.S. government retained a powerful colonial influence through its territorial management of Natives. The Indian Citizenship Act and the Indian New Deal - where this book concludes - emblemize the prevalence of the identity duality of U.S. citizenship that amalgamated American Indians to the nation, yet segregated them on reservations outside the spaces of U.S. society. This duality of inclusion and exclusion was built incrementally and existed as residues of nineteenth century Native-U.S. rhetorical relations.

Stain Removal - J. Reid Miller - Bog - Oxford University Press Inc - Plusbog.dk

Stain Removal - J. Reid Miller - Bog - Oxford University Press Inc - Plusbog.dk

Martin Luther King, Jr. famously expressed his dream that his children would "one day not be judged by the color of their skin, but by the content of their character." In his vision, a person''s ethical qualities would be understood in spite of his or her body rather than through it. In general, we think that a person''s actions should not be judged according to their physical features, such as race. In fact, we see evaluations based on a subject''s race or other bodily traits as illegitimate. But Stain Removal argues that our perception of a person''s actions always entails judgments of the body. It therefore challenges modern moral theory''s premise that a subject''s deeds and not its bodily traits count as primary objects of evaluation. Drawing on modern and pre-modern accounts of how ethical knowledge originates, from the Biblical story of Ham, to Socrates, Immanuel Kant, Alain Locke, Frantz Fanon, Langston Hughes, Onora O''Neill, and Louis Althusser, the book suggests that our recognition of both a person and that person''s deeds demands an evaluative context. From this it proposes that all perception is "evaluative perception." Through the metaphor of the stain, J. Reid Miller traces the long history of thought suggesting that embodiments like race can and do signify ethical qualities. He argues that these qualities do not "attach" to subjects from the outside -- like a stain on innocent and unraced beings -- but are instead what allow us to see people as distinct ethical individuals. The objective of ethics, he shows, is not to determine whether race is good or bad but to illustrate how our "unique" personal traits emerge through our multiple relations to others. The consequence is that, contrary to King''s vision, it is only through judgments of "skin" and other bodily features that the ethical "content" of subjects can be recognized.
