Skillnader i vatten- och avloppshantering inom EU : En jämförelse mellan Slovakien och Sverige

The management of water resources and waste water varies between the countries of the EU. For many years, a large part of the water in Europe has been contaminated by, among other things, insufficiently treated waste water and emissions from agriculture. The EU Water Framework Directive 2000/60/EC and the Urban Waste Water Directive 91/271/EEC are intended to harmonize fresh-water management and waste water management within the whole EU, aiming at safeguarding drinking water of good quality and a high quality of all water within the EU today and in the future. There are however some problems concerning the waste-water directive. One problem is the huge investment needed in Slovakia to fulfil the demands of the waste-water directive for waste-water management in larger communities (with more than 2000 inhabitants).

Jämförelse mellan våtkompostering och andra VA-system i omvandlingsområden : en fallstudie i Norrtälje kommun.

Eutrophication of the Baltic Sea and Swedish lakes remains a major problem despite many years of effort to reduce the emissions of nutrients. One major source is waste water systems, especially Private sewage systems. These sewages accounts for a very large share of nutrients per capita in comparison with citizens connected to larger sewage treatment plants. Norrtälje community has the greatest number of Private sewage systems in Sweden. Discharges of nutrients, especially phosphorus, to the Baltic Sea from these sewage systems are significant.

Rationell riskanalys inom VA-verksamhet med avseende på säkerhet, hälsa, miljö och kvalitet

This master thesis is developed based on the desire of the water and sewage department in the municipality of Karlskrona. The department, which vouches for the quality of produced drinking water and sewage cleaning, was in need of help dealing with risk analysis.The water and sewage department is obliged to identify and assess risks according to Swedish legislation. However, no guides for this purpose regarding safety, health, environment and quality were available. The aim of this report was to accomplish a guideline for the performance of risk analysis within water and sewage plants. If the guideline is used, the requirements in the legislation will be obtained.

Sammanställning och utvärdering av små avloppsanläggningar utifrån tillförlitligheten hos angivna reningsgrader

The Private sewage systems in Sweden releases around 600 tons of phosphorus per year, compared to about 350 tons from municipal sewage treatment plants, and they account for approximately 21% of the total anthropogenic discharge of phosphorus into Swedish waters. About 40% of Sweden's nearly 1 million Private sewage systems are inferior with respect to emissions to surface and groundwater. The technology of small sewage plants is under development and knowledge of treatment effects for different solutions is poorly consolidated. Municipal authorities lack resources to keep up with the technologic development and assess the reliability of the treatment performances that suppliers report for their products. The thesis aims to conduct a market review and evaluation of wholly or partially prefabricated small sewage plants, to make it easier for municipalities and property owners to assess different technical solutions. The goal is a compilation of the products on the market, evaluated on the basis of the reliability of specified degrees of reduction.Information on sampling procedures and test results were collected through a questionnaire to all active suppliers and the responses were then used to classify the products.

Kraven på ägare till minireningsverk skiljer sig åt mellan olika kommuner

Discharge of inadequately treated waste water containing nutrients such as phosphorus and nitrogen as well as organic matter and bacteria is associated with a risk of eutrophication and contamination. The Swedish government has decided upon several Environmental Quality Objectives aiming to reduce the emissions of nutrients to water bodies.In Sweden, there are between 675 000 to 1 000 000 on-site sewage systems. Recent studies have shown that the function of small sewage treatment plants is in many cases insufficient. To prevent this regular service and supervision by a professional is needed. The focus of this study are small sewage treatment plants which use a technique where mechanical, chemical and/or biological reduction of pollutants is being used in the same facility to reduce nutrients in household wastewater.The aim of the study is to investigate how different municipalities ensure that small sewage treatment plants fulfill the requirements and reduce pollutants as efficient as the manufacturers claim.

Utvärdering och framtagande av åtgärdsförslag för de mindre avloppsreningsanläggningarna i Laholms kommun : En studie av fem avloppsreningsanläggningar upp till 500 pe

The aim of this project was to describe and to evaluate five small sewage treatment plants in the municipality of Laholm, Sweden, in order to investigate the treatment efficiency and to evaluate if effluents comply with discharge permits. The treatment systems were designed to treat effluents from 90 to 500 population equivalents. A report on the design and the present state of each sewage treatment plant has been made. This was made based upon previous documentation on water quality and by new sampling campaign as there were only a few previous measurements. Data has been evaluated and remedial actions proposed for those treatment plants that don?t fulfill discharge permits.

Miljösystemanalys av VA-system i omvandlingsområden : fallstudie i Värmdö kommun

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.

Slam ? en outnyttjad resurs i skogsbruket

Every year about 210 000 tones dry weight of sewage sludge is produced in Sweden. Most of the sludge is applied to agricultural land, plantsoil and landfill cover. Sewage sludge contains essential nutrients such as nitrogen and phosphorus. Nitrogen is limiting growth on solid ground in Sweden and can therefore be used as fertilizer to increase productivity. In order that the sludge can be spread to forest land it requires first a conversion of sludge to pellets, to make it more manageable.

Vatten- och avloppssystem i klimatförändringarnas tidevarv : - en studie om VA-situationen i Karlstads kommun, dess sårbarheter och anpassningsförmåga

This report is about the impact climate change has on the water and sewage systems in general, and the situation in the municipality of Karlstad in particular. Which vulnerabilities are linked to water and sewage systems with regard to climate change and extreme weather situations, what are the possibilities to adapt the system to this and what significance does climate adaptation of the water and sewage systems have in relation to sustainable development?To answer these questions I have studied literature on the subject and interviewed several people who work with these types of questions. The answers I have received state that there are a multitude of vulnerabilities linked to the water- and sewage systems, but that there are also many strong interests which strive to take measures and adapt to a changed climate. I have also come to the conclusion that the starting points and views of the possibilities to act differs between the people that I have interviewed, but that theses problems are built into the concept of democracy..

Undersökning av utökade användningsområden för Lotsbroverkets slam

Lotsbroverket is the largest wastewater treatment plant on the Aland Islands and it isdesigned for handling wastewater from approximately 30 000 persons. In 2011,Lotsbroverket produced about 2800 m3 of dewatered sludge. The sewage sludge that isproduced is transported to a contractor where it is processed to eventually be used e.g.in the construction of green space. This study aims to investigate available applicationoptions in terms of the sewage sludge that is produced in Lotsbroverket. The main aimis to study the feasibility of using the produced sewage sludge as a fertilizer in theagriculture of the Aland Islands.The sludge already fulfills limit values for heavy metals in accordance with the Act"The Aland Government´s directive on the use of sewage sludge in agriculture." Inorder to clarify the sludge content of pharmaceutical and organic substances it isrequired that the substances are identified and a risk assessment is performed.

Finanskrisens inverkan på styrning av private equity-bolagens styrning av portföljbolagen: En fallstudie av Accent Equity Partners

Abstract: Private equity used to be synonymous with tremendous yields and rates of return. However, the private equity market trembled in 2008, due to the financial meltdown caused by the worldwide credit crisis. Considering the current low number of exits within the private equity industry, the purpose of this thesis is to examine if there has been any change in how private equity firms control their portfolio companies since the inception of the crisis. One private equity company and two portfolio companies have been studied. The case study is prepared from interviews with senior directors in the portfolio company and investment managers in the private equity firm.

Social upphandling : Ett uttryck för public-private partnership?

The purpose of this thesis is to examine how social procurement can be a further development of public-private partnership. This is done with interviews and a case study of the social procurement Mitt Gröna Kvarter and its labor effort Boendebyggarna. The theoretical framework used in the thesis consists of public-private partnership and corporate social responsibility. It tries to answer the following questions:What does this social procurement mean by the concept of public-private partnership?What does this social procurement mean for the participants involved?How can social procurement be seen as a further development of public-private partnership?The thesis uses the theory development around the concepts of public-private partnership and corporate social responsibility and shows that social procurement does indeed have similarities to public-private partnership and could very well be a further development of it..

Värderingsmetoder ur ett Private Equity-perspektiv

Uppsatsen behandlar de investeringskriterier och värderingsmetoder som svenska Private Equity-företag använder inför företagsförvärv. Vi har gjort en kvalitativ analys av fem svenska Private Equity-aktörer. Våra slutsater är att de Private Equity-bolag vi studerat har ett fåtal övergripande investeringskriterier men att de är relativt flexibla gällande resterande. Företagen använder sig främst av multipelvärdering i värderingsprocessen. Sammanfattningsvis kan vi konstatera att Private Equity-företagen fokuserar mindre på vad företaget är värt och lägger allt fokus på hur mycket företaget kan avyttras för..

Hur påverkar en lansering av EMV det ekonomiska resultatet i en kategori -En kvantitativ studie om EMV lanseringar i sällanköpshandeln-

Private label introductions have been increasing in recent years. The main reason for this is that private labels increase the retailer's profits in the category. The purpose of this study is to examine how a private label introduction affects the category's performance. This study was conducted by studying the category's performance before and after the introduction, two categories are examined. Data have been collected at a Swedish retailer and consists of 38 stores, all located in Sweden and within the same store profile..

Att smöra för EMV kan smälta kategorin

Private labels have been increasing a lot during the last 30 years. The reason is great margins and it also works as an aid to build a store's brand. The problem is that private labels take market shares from national brands. Retailers need to have a good mix between these products and adopting category management without being influenced by opportunism, which can lower the profitability of a category. The purpose of this study is to examine and describe how private labels are prioritized in the category edible fat.
