Cat People: Human–Cat Interrelatedness in the Cat Fancy - Emily Stone - Bog - Taylor & Francis Ltd - Plusbog.dk

This book examines the social world of the cat fancy, or the leisure activity of breeding and exhibiting pedigree cats. Based on multispecies ethnographic fieldwork and interviews in the United Kingdom, it explores the process and performance of exhibiting cats at shows, the breeding practices and discourses integral to the creation of pedigree breeds, and the relations that these practices generate between human guardians, the pedigree cat population, and non-pedigree cats. Through observation with cat fanciers and their interactions with their cats, the author investigates the social dynamics and relationships that form within the fancy, considering the interconnections between biopower and eugenics in pedigree breeding, the practices of pet keeping and the complexities of more-than-human care, and the implications of involvement for the cats themselves. As such, Cat People: Human–Cat Interrelatedness in the Cat Fancy will appeal to scholars from across the social sciences and humanities interested in human–animal interactions, multispecies leisure, anthrozoology, and more-than-human care.

Autotrophic Nitrogen Removal from Low Concentrated Effluents - Javier Adrian Sanchez Guillen - Bog - Taylor & Francis Ltd - Plusbog.dk

On a global scale, sewage represents the main point-source of water pollution and is also the predominant source of nitrogen contamination in urban regions. The present research is focused on the study of the main challenges that need to be addressed in order to achieve a successful inorganic nitrogen post-treatment of anaerobic effluents in the mainstream. The post-treatment is based on autotrophic nitrogen removal. The challenges are classified in terms of operational features and system configuration, namely: (i) the short-term effects of organic carbon source, the COD/N ratio and the temperature on the autotrophic nitrogen removal; the results from this study confirms that the Anammox activity is strongly influenced by temperature, in spite of the COD source and COD/N ratios applied. (ii) The long-term performance of the Anammox process under low nitrogen sludge loading rate (NSLR) and moderate to low temperatures; it demonstrates that NSLR affects nitrogen removal efficiency, granular size and biomass concentration of the bioreactor. (iii) The Anammox cultivation in a closed sponge-bed trickling filter (CSTF) and (iv) the autotrophic nitrogen removal over nitrite in a sponge-bed trickling filter (STF). Both types of Anammox sponge-bed trickling filters offer a plane technology with good nitrogen removal efficiency.

Effect of Algal Biofilm and Operational Conditions on Nitrogen Removal in Waste Stabilization Ponds - Mohammed Babu - Bog - Taylor & Francis Ltd -

Discharge of nutrient rich wastewater causes eutrophication of surface water; therefore wastewater treatment before discharge is required. Wastewater stabilization ponds are low cost technology used by developing countries but not effective in nitrogen removal due to low nitrifier biomass in the water column. Introduction of surface area for attachment of nitrifiers has therefore been proposed. This thesis reports the performance of pilot scale wastewater stabilization ponds fitted with baffles. The effect of baffles on nitrogen removal under tropical and two operational conditions was investigated. Under TKN/BOD ratio of 0.67, the baffled ponds performed better in nitrogen removal than the control pond. Total nitrogen mass balances showed that nitrification-denitrification, algal uptake and sedimentation were principle nitrogen removal mechanisms in biofilm waste stabilization ponds This study shows the potential of biofilms in improving nitrogen removal in wastewater stabilization ponds. The BOD and TSS concentrations were sufficiently low to permit for reuse in irrigation. If the objective is reuse and optimization of resources, the effluents from the ponds had sufficient nitrogen content for use in agriculture.

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.

Pathogen removal using saturated sand columns supplemented with hydrochar - Jae Wook Chung - Bog - Taylor & Francis Ltd - Plusbog.dk

Lack of clean water is one of the most important public health challenges in less developed communities. Due to insufficient financial and technical resources in places in need, development of low-cost water treatment technologies can play a key role in sustainable water provision. In this context, this PhD research investigated the removal of pathogenic microorganisms in simple sand filtration set-ups supplemented with low-cost adsorbents (hydrochar) produced via hydrothermal carbonization of biowastes. Two types of hydrochar, derived from hydrothermal carbonization of agricultural residue of maize and stabilized sewage sludge from wastewater treatment plant, were evaluated as adsorbents for Escherichia coli removal in saturated sand columns. The removal efficiency of sand columns amended with these adsorbents improved from 20-70% to ~90 % by alkali activation carried out in room temperatures using 1 M potassium hydroxide solution. This PhD research also demonstrates the removal of human pathogenic viruses in sand columns supplemented with hydrochar adsorbents derived from stabilized sewage sludge and fresh swine waste. In order to enumerate human pathogenic rotavirus and adenovirus in virus removal experiments, low-cost polymerase chain reaction assays were developed under this PhD study. These assays show a competent performance in analyzing virus concentrations in both laboratory and environmental samples. Amendment with either hydrochar (without alkali activation) in sand columns was able to remove more than 99% of both viruses.

Development of a Low-Cost Alternative for Metal Removal from Textile Wastewater - Christian Sekomo Birame - Bog - Taylor & Francis Ltd - Plusbog.dk

Industrial wastewater contains many pollutants. This book focuses on heavy metals found in textile effluents because of their known toxicity effect in the environment. Wastewater from a textile industry (UTEXRWA) in Rwanda has been screened for the occurrence of Cd, Cr, Cu, Pb, and Zn. Batch and pilot experiments on adsorption equilibrium, kinetics, and sulfide precipitation using volcanic rock as adsorbent and packing material have been investigated. A low cost and integrated system for treatment has been developed, combining an anaerobic bioreactor as the main treatment step, followed by a polishing step composed by a polishing pond containing algae, duckweed, and water hyacinth. More than 90% of metal removal was achieved in the bioreactor, with metal sulfide precipitation as long-term removal mechanism. The use of algae and duckweed as alternatives for water hyacinth plants showed no differences between algae and duckweed ponds based on abiotic differences. Overall, both systems'' performance was close and these systems are well suited as a polishing step for wastewater containing low metal concentrations. The integrated system for heavy metal removal showed how two complementary systems for heavy metal removal can work in combination and good removal performance can therefore be achieved.

Pathogen Removal Mechanisms in Macrophyte and Algal Waste Stabilization Ponds - E. Awuah - Bog - Taylor & Francis Ltd - Plusbog.dk

Pathogen removal mechanisms in macrophyte and algal-based waste stabilization ponds were studied in Ghana and Colombia. The macrophytes used were water lettuce (Pistia stratiotes) and duckweeds (Lemna paucicostata and Spirodela polyrhiza). The selection of the species was based on economic importance and availability. Lemna was used during the initial investigations. However, Lemna could not withstand the ammonia levels in the wastewater used. Spirodela polyrhiza a rarer species in Ghana was therefore used in subsequent studies. The main mechanisms considered in this study were pH, protozoa predation and surface attachment. The microorganisms used were faecal bacteria namely; Escherichia coli, other coliforms, Salmonella sp., other enterobacteria, E. coli, ATCC13706 and enterococci. Studies were conducted using batch scale, continuous flow bench and pilot scale ponds. Results indicated in order of importance that long retention periods, attachment, sedimentation, predation and low pH are mechanisms in macrophyte ponds enhancing faecal bacteria removal, while in the algal ponds long retention periods, sunlight penetration, high pH, attachment and sedimentation are the mechanisms of importance in faecal bacteria removal. Presence of protozoa was also found to be important but true grazing studies could not be quantified. Dissolved oxygen did not play a major role in faecal bacteria removal.

Adsorptive Removal of Manganese, Arsenic and Iron from Groundwater - Richard Buamah - Bog - Taylor & Francis Ltd - Plusbog.dk

Arsenic, manganese and iron in drinking water at concentrations exceeding recommended guideline values pose health risks and aesthetic defects. Batch and pilot experiments on manganese adsorption equilibrium and kinetics using iron-oxide coated sand (IOCS), Aquamandix and other media have been investigated and modeled. Effect of manganese and iron loading on manganese removal and rate of oxidation of adsorbed iron and manganese have been studied. Aquamandix and IOCS demonstrated iron and manganese adsorption capacity that increases with increasing pH under oxic and anoxic conditions. Manganese loading and low filtration rate using feedwater with no nitrite favour non-uniform development of catalytic manganese oxide on media that subsequently enhances manganese removal.

Pathogen removal in aerobic granular sludge treatment systems - Mary Luz Barrios Hernandez - Bog - Taylor & Francis Ltd - Plusbog.dk

This book describes pathogen removal processes in aerobic granular sludge (AGS) wastewater treatment systems. Faecal indicators ( E. coli , Enterococci , coliforms and bacteriophages) were tracked in full-scale AGS facilities and compared to parallel activated sludge (CAS) systems. AGS showed similar removals as the more complex CAS configurations. Removal mechanisms investigated in laboratory-scale reactors showed that the AGS morphology contributes to the removal processes. By tracking E . coli and MS2, it was observed that organisms not attached to the granules are predated by protozoa during aeration. 18S RNA gene analyses confirmed the occurrence of bacterivorous organisms (e.g., Epistylis , Vorticella, Rhogostoma) in the system. Particulate material in the feeding stimulated their development, and a protozoa bloom arose when co-treating with (synthetic) faecal sludge (4 % v/v). An overview of the diverse eukaryotic community in laboratory reactors and real-life applications is also provided. The microbial diversity of the influent was different compared to AGS and CAS sludge samples. However, no clear differences were found between them on species level. This study contributes to a better understanding of the mechanisms behind pathogen removals in AGS systems.

Metal Removal and Recovery from Mining Wastewater and E-waste Leachate - Suthee Janyasuthiwong - Bog - Taylor & Francis Ltd - Plusbog.dk

Metal contamination in the environment is a persisting global issue. The metal reservoirs in the earth have declined due to society’s needs and due to uncontrolled mining activities. Therefore, the idea to recover metals from waste streams has emerged. In this thesis, cost competitive technologies such as adsorption using agro-wastes and precipitation using an inverse fluidized bed (IFB) reactor were investigated, with special emphasis on the recovery of base metals. Groundnut shell showed good potential for metal (Cu, Pb and Zn) removal. From artificial neural network modeling, the performance of the sulfate reducing bacteria (SRB) was found to be strongly pH dependent; the removal efficiency of Cu and Zn in the IFB at pH 5.0 was 97%. Electronic waste is a good candidate as secondary metal resource. The recovery of Cu from computer printed circuited boards (PCBs) using biogenic sulfide precipitation was investigated as well. Using this technology, Cu could be recovered at ~0.48 g Cu/g PCBs.

Removal of the Property Qualification for Voting in the United States - Ronald F. (san Diego State University King - Bog - Taylor & Francis Ltd -

In Colonial America, democracy was centered in provincial assemblies and based on the collection of neighbors whose freehold ownership made them permanent stakeholders in the community. The removal of the property qualification for voting in the United States occurred over three-quarters of a century and was among the more important events in the history of democratization, functioning to shift voting from a corporate privilege toward a human right. Moving beyond the standard histories of property standard histories of property qualification removal, Justin Moeller and Ronald F. King adopt the theories and methods of social science to discover underlying patterns and regularities, attempting a more systematic understanding of subject. While no historical event has a single cause, party consolidation and party competition provided a necessary mechanism, making background factors politically relevant. No change in franchise rules could occur without the explicit consent of incumbent politicians, always sensitive to the anticipated impact. Moeller and King argue that political parties acted strategically, accepting or rejecting removal of the property qualification as a means of advancing their electoral position. The authors identify four different variants of the strategic calculation variable, significantly helping to explain both the temporal differences across states and the pattern of contestation with each state individually.
