The task of the master’s thesis is a study focused on re-use and process wastewater in the company Kostelecké uzeniny a.s. The thesis contains a description of wastewater treatment plants, sewage flow and metabolic load on each water treatment processes. The thesis describes the limit requirements for technological processes within the enterprise. Few variants of the use of alternative water sources for technological processes on the basis of health conditions that has been designed for treating waste water from truck wash were considered in the thesis. Treated waste water is being re-used within the truck wash. Part of the proposal is also economic calculation and evaluation of return on investment.

The recent and rapid growth of horizontal drilling in the Anadarko basin necessitates newer studies to characterize reservoir and source rock quality in the region. Most oil production in the basin comes from the Granite Wash reservoirs, which are composed of stacked tight sandstones and conglomerates that range from Virgillian (305-299 Ma) to Atokan (311-309.4 Ma) in age. By utilizing geophysical well logging data available in raster format, the Granite Wash reservoirs and their respective marine flooding surfaces were stratigraphically mapped across the regional fault systems. Additionally, well log trends were calibrated with coincident core data to minimize uncertainty regarding facies variability and lateral continuity of these intervals. In this thesis, inferred lithofacies were grouped into medium submarine fan lobe, distal fan lobe, and offshore facies (the interpreted depositional environments). By creating isopach and net sand maps in Petra, faulting in the Missourian was determined to have occurred syndepositionally at the fifth order scale of stratigraphic hierarchy.

This research aims to further explore the linkages between poor WaSH realities and women’s development to understand how the burdens and risks associated with inadequate water resources diminishes both their health and safety. Specifically, a significant goal of this project is to understand the way in which rates of violent attacks increase as access to water decreases. Attempting to capture this violence in all its various forms, this study hosts conversation surrounding the way that a lack of clean, dependable water sources can increase a woman’s chances of experiencing various forms of violence. / Accessing clean water and adequate sanitation poses significant risks to the health and wellbeing of women and girls in East Africa. Without having access to local and dependable sources of water, the prevalence of water-borne diseases, health and safety hazards, and social barriers increase. Grounded in Feminist and Structural Functionalism theories, this research was designed to better understand Water, Sanitation, and Hygiene (WaSH) realities and the various types of associated burdens and risks. Using focus groups and key informant interviews, 36 health care professionals from various East African countries, such as Uganda, Tanzania, Ghana, and South Sudan, were solicited in an effort to capture the real, lived experiences of practitioners working most intimately with these issues. All data were gathered at Uganda Christian University in Mukono, Uganda, and reflect both the personal and professional accounts of health care professionals living and working throughout communities within these countries. The findings of this study indicate that for as long as poor water and sanitation access and hygiene practices continue to plague the development of women in urban and rural communities, women and pregnant women will continue to suffer from dangerous diseases and brutal attacks of violence. Honing in on the latter concept, this study uncovered a significant link between inadequate water access and rates of domestic violence, sexual assault, and animal attacks. Understanding the health professional perspective is crucial in gathering relevant data. Through this effort, the findings of this study have been informed by those most knowledgeable on the WaSH realities identified and therefore has the ability to influence both policy and programs in realistic and productive ways. With the goal of determining and then diminishing identified risks, the data gathered from this research are meant to be used as evidence to help empower and advance women throughout East Africa. / Thesis / Master of Social Work (MSW)

No / Surfactants are commonly used as cleansing agents and yet there are concerns they may also have a role in skin irritation. Presently, the lack of suitable methods for quantitative and qualitative analysis of surfactant deposition on skin has hindered the in-depth investigation of such effects. Here, we report the application of reverse phase liquid chromatography electrospray ionisation mass spectrometry (LC/ESI-MS/MS) assays for two surfactants commonly used in consumer products, namely sodium lauryl ether sulphate (SLES) and laurylamidopropyl betaine (LAPB), to a baseline study aiming to assess deposition levels on human skin. The linearity of the assays was established at 3-20 ng, with coefficient of variation below 5%. Detection limits were 100 pg for LAPB and 1 ng for SLES; quantitation limits were 500 pg for LAPB and 2.5 ng for SLES. The baseline study was conducted using a panel of 40 healthy volunteers. Skin extract samples were taken in triplicate from forearms, using ethanol. SLES was detected on most volunteers, with 75% of them having SLES deposits in the range of 100-600 ng/cm2. LAPB was detected on the skin of all volunteers with 85% of them having deposit levels within the concentration range of 1-100 ng/cm2. These results demonstrate the extent to which commonly used surfactants remain on the skin during the day. The analytical methods reported here can be applied to the investigation of surfactants in relation to general skin condition and the development and optimisation of new consumer wash products. / EPSRC

Massatvätt är ett viktigt steg i kraft-processen, då kokkemikalierna kan återvinnas och återanvändas i processen, vilket minimerar belastningen på miljön. Det är ett viktigt steg innan blekning av massan, då en låg kemisk syre-förbrukning (COD) är viktigt för att minska förbrukning av blekningskemikalier. Dessutom kan massatvätt även eliminera andra oönskade material, såsom metaller eller extraktivämnen. Syftet med studien var att utvärdera av tvätt-effektivitet av industriell massatvätt. Målen var att jämföra industriell tvättning med extensiv tvättning, att undersöka kvaliteten av tvättvätskor med analystekniker och att undersöka befintliga metoder för att beräkna tvätt-effektivitet. Den experimentella fasen var indelad i provtvättning och tvätt-serier, utförda med olika tvättvätskor, uppehållstider och industriell och extensiv utspädningsfaktor. Provtvättningen gav resultat som möjliggjorde det att utveckla tvätt-metoden. Resultaten för tvätt-serien visade att den extensiva utspädningsfaktorn generellt gav bättre resultat och en mer effektiv tvätt, och att en tvättvätska med en temperatur på 80°C generellt gav bättre resultat. Ljusheten påverkades inte av utspädningsfaktorn och kappanalysen visade en väldigt liten skillnad jämfört med originalmassan. Utvärderingen av befintliga metoder för att beräkna tvätt-effektivitet indikerade att alla undersökta metoder kunde ge felaktiga resultat, men beräkningarna tillsammans med andra metoder såsom COD, konduktivitet och med flera borde ge industrin en god indikation på tvätt-effektiviteten / Pulp washing is an important step in the kraft process, as it allows for the cooking chemicals to be recovered and reused in the process, which also minimizes the environmental load to the subsequent stages. It is also important before the bleaching plant, as a low chemical oxygen demand (COD) carry-over is important to minimize the consumption of bleaching chemicals. Furthermore, washing can also remove other unwanted materials, such as metals or wood extractives. The aim of the study was to assess washing efficiency of industrial washing. The objectives were to compare industrial washing with extensive washing, to investigate the quality of wash liquors using analytical techniques and to examine existing methods for calculating washing efficiency. The experimental phase was divided into trial washing and washing series, conducted with different wash liquors, residence times and dilution factors (DF). The trial washing yielded results that allowed for the washing methodology to be improved. The results from the washing series indicated the extensive DF in general gave better results and provided a more efficient washing, and that a wash liquor of 80°C gave better results. Brightness was not affected by the dilution factor and kappa number analysis showed that there was a very slight difference compared to the original pulp. The evaluation of existing methods for calculating washing efficiency indicated that all investigated methods could give inaccurate results, but that the calculations together with other methods such as COD and conductivity should give the industry a good indication of the washing efficiency.

Access to water from San Antonio Creek was critical in Claremont’s growth from a small stop on the Santa Fe Railroad to an agricultural powerhouse and an elite college town. While Claremont has sought to distinguish itself from surrounding communities since its founding in 1882, the innovative Pomona Valley Protective Association (PVPA) aligned Claremont with the City of Pomona and its other neighbors in a scheme to conserve the Creek’s resources at the turn of the century. Organized around the discovery of local confined aquifers and the development of a strategy to recharge them with water from the San Antonio Creek, the Association was a contradictory moment of cooperation in an otherwise highly contentious zero-sum game of water rights politics. As conflicts wore on, the PVPA quietly orchestrated the purchase of large tracts of land in the San Antonio Creekbed, where the construction of diversion dams and spreading grounds served dual purposes of water conservation and flood control. As dam building in the Creekbed continued, large tracts of the previously undevelopable Wash were transferred to the aggregate mining institutions that gouged the area’s many gravel pits. This thesis uses the story of the PVPA and the contemporary example of the Claremont University Consortium Gravel Pit to explore the context of development in the San Antonio Creek Wash. Understanding the political and social contexts of the gravel quarry problem reveals possibilities for a more integrative, conscious, and sustainable approach to improving the former gravel quarries that currently occupy the Wash landscape.

The location of the site where the pioneers settled permanently was determined by the availability of water in the immediate environment. The Highveld contains fertile soils, a fine climate, and an abundance of water. The area has always been extensively used for crop and stock farming, but in general, mixed farming was practiced. The farmers depended on the availability of water, therefore their experiences, observations, weather forecasts, and conclusions, developed into a popular folk meteorology. Furthermore, environmental factors such as local topography, micro climate, hydrography, ground fertility, and the appearance of natural vegetation determined whether or not an area was suitable for permanent residence. The farmstead may be divided into three functional zones (the core-, extended-, and outer farmyard) that are joined by a canal network, used for irrigation and drinking water. The farmhouse and buildings, erected a stones throw away from the water source, served as a focal point for the activities of the farmer. The manipulation of the water source by obstruction of streams and the construction of water canals, weirs and water furrows, assisted the farmer in planning his activities and in using the water to his advantage. The settlement and development of the residence on the rural parts of the Highveld may be divided into three distinct phases. Firstly, the temporary trekboer phase, secondly the pioneer phase and thirdly the permanent settlement phase. The permanence of residence had a direct influence in the layout of the house, the method of construction, and the use of the available water supply. At first, the trekkers were content to reside in roof dwellings (their wagons and tents and a grass screen as their kitchen and a hut near a spring). The first houses were hartbieshuise and kapsteilhuise. The more permanent homesteads of the earlier settlers were a simple rectangular structure (pioneer house) with a saddle grass roof. With the introduction of galvanised iron sheeting, the house was expanded and developed into the veranda-, stoeproom- and a flat roofed rectangular house. This development resulted into a typical rural Highveld homestead. After the discovery of gold in the vicinity of the Witwatersrand, the first gold rush took place resulting in the proclamation of Johannesburg in 1886. Prospectors, mostly foreigners, descended upon the Witwatersrand. Housing took on a more planned structure resembling the late Victorian period of housing in England. The water supply and drainage systems were planned and improved, making it possible to provide running water to kitchens and bathrooms. This impacted firstly on the upper riches of society in the cities, later on the lower middle classes and lastly on the rural areas. European technology regarding the supply of hot pipe water and drainage systems changed the layout of the house. The cooking activity moved from outside behind a screen to a seperate room inside the house. Inevitable changes regarding collecting, storage, purpose, saving and drainage of household water took place. Between 1840 and 1910, evolutionary changes took place regarding sanitation, water supply and personal hygiene. Being part of a particular social class made certain facilities available to certain individuals. A rural Highveld dwelling rarely included sanitary facilities, instead dwellers had a more primitive wash basin in each room in which they washed daily. On a Saturday, a weekly bath was taken in a bathtub in the kitchen or bedroom. Trekkers simply relieved themselves outside. A revolution in sanitary habits and facilities became inevitable. The Victorian dwelling on the Highveld was built according to a standard plan, including a flush water system already in place. This was the ultimate manifestation of sophistication and civilization. The aim of this investigation is to identify the similarities and differences between the use of water by the pioneer, the poor people and the wealthy in their rural dwellings. Furthermore, information has been obtained regarding water usage and sanitation in the bathroom and kitchen in the rural dwelling to be useful in the area of historic architecture and the heritage of our water history. / Thesis (M.A. (History))--North-West University, Vaal Triangle Campus, 2008.

A presente pesquisa teve como objetivo levantar dados básicos para posterior composição de indicadores de sustentabilidade, em postos de combustíveis, funilarias e estabelecimentos de lavagem automotiva no município de São Carlos, tendo em vista a busca de soluções para questões sociais, ambientais e econômicas que garantam sustentabilidade nesses tipos de empresas. Foram feitas visitas com entrevistas e aplicação de questionários em cada estabelecimento, coletados resíduos sólidos industriais em quatro estabelecimentos de cada tipo de empresa e em seguida caracterizados esses resíduos. Para a classificação de resíduos foram feitos ensaios de lixiviação e solubilização. Os produtos mais utilizados nas empresas estudadas foram classificados como classe I-perigosos. Apesar disso, os resíduos coletados foram classificados como não perigosos, classe II A - não inertes, possivelmente devido à dissolução dos produtos perigosos. Com base no tratamento dos dados obtidos determinaram-se alguns indicadores que, por vezes, mostraram-se mais eficientes quando analisados em conjunto com outros. Ao se confrontar Indicadores de Consumo com Indicadores de Produção, por exemplo, pôde-se prever a dimensão de lucros e prejuízos sociais, financeiros e, sobretudo ambientais do empreendimento. Constatou-se a partir da análise de indicadores estudados que nas empresas em questão, existe falta de investimentos em pesquisas e tecnologias que garantam desenvolvimento sustentável das mesmas. Existe também carência de investimentos em capacitação de funcionários que busque melhorias na qualidade, no meio ambiente, sociais e na segurança dos trabalhadores, e assegure assim o desempenho sustentável das empresas em foco. / The aim of this research was to raise basic data for composition of Sustainability Indicators in gas stations, car body repair and painting shops and car wash establishments in São Carlos city, in order to find solutions to social, environmental and economical issues. This would ensure sustainability in these businesses. Visits were made with interviews and questionnaires application in each establishment, industrial solid wastes were collected in four establishments of each type of enterprise and then these wastes were characterized. The wastes classification was made by chemical tests. Most products used in studied enterprises were classified as class l-hazardous products. Nevertheless, the collected wastes were classified as non-hazardous waste, class II A- non inert, possibly due to the dissolution of hazardous products. Some indicators have been developed from processing of obtained data. Sometimes indicators proved more efficient when examined together with others. When Consumption Indicators are worked with Output Indicators, for example, the dimension of profits and losses from social, financial and above all environmental area can be provided to the venture. Indicators showed investment in researches and technologies, as well as in training for improvements in quality, environment, social and workers safety would ensure sustainable development in the enterprises.
