This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.

Hammarby Sjöstad is a new district in Stockholm with high environmental standard. Stockholm Water Company evaluates a local wastewater treatment plant with cutting edge technology. The first step is an experimental treatment plant (Sjöstadsverket) with four parallel lines of treatment, each with a capacity to treat wastewater from 150 persons. Within the membrane technology subproject the possibility of using reverse osmosis (usually called RO) to regain nutrients is examined.Reverse osmosis separates the incoming water in a clean permeate and a concentrate that, as the name indicates, is a more concentrated version of the incoming water. Using this method in wastewater treatment, a solution high in nutrients can be obtained without the use of chemical precipitation agent and with no production of sludge.

The fishing port of Bläsinge is located on the east coast of Öland, Sweden?s second largest island. Today the port has a limited supply of freshwater. The economic association of the fishing port wants to expand their business, so that they will also include tourist services. To do this the harbor will need a more independant source of freshwater, with a higher quality than the present well.

The continuous process of urbanization results in demands on research and development for ecological and sustainable city development. Because of this, the current systems for wastewater treatment may have to be improved. In order to evaluate new technologies for municipal wastewater treatment, a development project has been initiated for the new district Hammarby Sjöstad in Stockholm. The project is lead by the company Stockholm Water. High environmental standards have been put up for the district, as it must be twice as good as an ordinary new district.

This study looks at Laleh Bakhtiar´s ambitions when it comes to The Sublime Quran, her English translation of the Quran. It also contains a look at how it was received in English and American media, and how Bakhtiar and her like-minded defend her interpretation and translation against critics, focusing on verse 4:34..

AbstractThis essay examines the idea of unity in the early church, based on Psalm 133:1. My interest in this was awakened during a seminar with the scholar Sr. Dr. Michaela Puzicha OSB, who proposed that St. Benedict of Nursia in his Rule, RB 42, alludes to Ps.

Wastewater treatment is increasingly controlled by the Swedish environmental quality objectives, adopted by the Swedish parliament. There is a need for a sewage system that can fulfill stringent requirements concerning the environment, recycling and resource use and hygiene. Additional environmental aspects in recent years are the impact of climate change, new knowledge about the effects of pharmaceuticals in water, the need for improved wastewater treatment and increased recycling of nutrients to agriculture. This report has, from a future scenario of the year 2050, analyzed seven different systems for wastewater treatment and treatment of compostable biowaste from households in Eskilstuna. A future scenario was chosen based on that within a forty year period new challenges may arise which can result in higher demands on sewage treatment than those we see today. Another reason why the future scenario was established is that changes in wastewater treatment systems are slow to establish. The analysis is mainly focused on the economical aspects but environmental aspects such as emissions to receiving waters and potential recycling of plant nutrients has also been evaluated briefly.

During the last few years the presence of high arsenic (As) concentrations in ground water has been of major concern both internationally and in Sweden. Much evidence has been reported about toxic effects caused by arsenic. The carcinogenic effects and the possibility to measure the toxic impacts at low concentrations made the World Health Organisation (WHO) to reduce the guideline value from 50 to 10 ?g l-1 in 1993. In Sweden the corresponding reduction was implemented in 2003. Several surveys in Sweden have shown that high arsenic concentrations may occur in ground water.

My working process is craft based and influenced by devotion for the textile material and techniques, but the concept is just as important. I mainly do sculptural objects where I treat fascination, frustration and disgust for the human body from a personal perspective. I am also deeply fascinated with Michael Jackson; an iconic figure that I adore above all else. A man with an inner musical ability, dedicated his entire life to tame and signify it through his body. My master work is an investigation where I look upon similarities and connections between my fascination with the body and the admiration and fascination with Michael Jackson.

Nanofiltration is a proper way of preparation of drinking water. The process has a lot in common with reverse osmosis where a semipermeable membrane is used to separate a pure water flow from the remaining water. A pilot plant was used to ensure that nanofiltration is a suitable technology for a specific waterworks station in Glemmingebro, Ystad. The purpose was also to find out if a pH-adjustment is needed for feed water in a possible full scale plant.  In this case nanofiltration is used mainly to remove sulphate and calcium since the raw water contains concentrations of these substances which exceed the limits for potable water. It is important to receive a high recovery (RC), otherwise the deliviery of water won?t be high enough.

The aim of this study is to analyse how pornography is used in the American comics X-Men, published by Marvel under the authorship of Chris Claremont.I have applied Butler and MacKinnons theories about pornography as a performative speech, to this special art form. I have also investigated how censorship has influenced the comics evolution and whether it has affected the way women and sexual and ethnical minorities are represented. To corroborate how these theories apply, I have analysed three main female fig-ures in The X-Men comics - Storm, Phoenix and Shadowcat - and I have tried to identify how they relate to existing stereotypes.The conclusion of this essay is that the women characters in X-Men break the existing stereo-types and create new implications. This reinforces Butler?s theory about the possibility to re-verse hate speech and diminishes MacKinnons perspective of pornography as an imperative..

Wastewater handling of private sewage systems has become an all increasing matter. In Stockholm region the 90 000 private sewage systems contribute with larger phosphorus flows to the Baltic Sea than the two biggest sewage plants in the area, Henriksdal and Käppala, contribute together, even though these two plants purify wastewater from more than one million inhabitants. When summer house areas turn into areas for permanent living ? transition areas ? the load on the existing systems increases, systems that already often are unsatisfying. In those areas it is not clear what the best system choice is; On-site systems for single households; Local collective systems or Connection to central systems.

The aim of this study is to explore the approach and views on female genital mutilation(FGM) among young women from Somalia, and how they perceive the tradition afterimmigration to Sweden. This is structured under the following questions: What do theyknow about FGM? What are their experiences? And what do they reckon about FGMtoday? The study is based on one recorded interview with a group of young femalesfrom Somalia. The data were analysed using qualitative content analysis. The women?sfeelings were ambivalent though they on one hand opposed FGM because of serioushealth risks, but on the other hand were conscious of the tradition?s great influence inthe social network and daily life.

Abstract/Sammanfattning Syftet med detta arbete är att med en narratologisk metod undersöka hur femininitet och maskulinitet representeras i relation till våld i serien Firefly och filmen Serenity. Detta görs med fokus på huvudkaraktärerna Malcolm ?Mal? Reynolds och River Tam. Som teoretisk grund används teorier om och kring representation, stereotyper, genussystemet, samt maskulinitet och våld. Våldet undersöks utifrån tre aspekter, hur karaktärerna utsätts för våld, hur de använder sig av våld och vilka motiven är i deras våldsutövande.
