This report is about the experiments with mixing of the separated Water and the vacuum pump seal Water at Hellisheiði power plant. This is done to prevent silica scaling and clogging in pipes and reinjection wells as well as eliminating vacuum pump seal Water from the plant. The experiments were done in four stages: the first stage comprised of tests with different flows of separated Water at 70°C, the second stage was carried out by mixing the separated Water at 70°C and the seal Water with different amounts of the seal Water, the third and the fourth stages were like the first and second but with the separated Water at 120°C. The results show that this method is good if the mixture is around 50/50 separated Water and seal Water, to control the silica scaling in the separated Water and to be able to reinject the seal Water with the separated Water. This does not eliminate the silica scaling in all of the separated Water because the amount of separated Water is much more than the amount of seal Water that comes from the plant. .

We all know that Water is very important for both animals and humans. When we are weaning the piglets from the sow we must guarantee that the piglets can start to drink more Water instead of sow milk. The first thing to check is always the quality of the Water that is to be used. To secure that, you must take a Water sample. If the Water is inadequate it can bring a lot of problems and diseases.

Water is an important food and an important natural resource. In order to protect these are the Environmental Code and the EU directive given to Water protection and related Water protection regulations will be established for all Water sources until 2010. Those who will prepare a Water protection and related Water protection regulations is the municipality or person responsible for Water supply. The person then decides and declares the area as Water protection and related Water protection regulations are municipal or provincial government. The idea of creating a Water protection is to protect the Water supply and the body of Water against pollution caused by point sources, diffuse sources and accidents combined.

The objective of this report was to analyse and compare vulnerability and preparation in Swedish municipal drinking Water production, in case the commonly used Water sources were inoperative. Methods used were a questionnaire and a less extensive study of regulations for Water protection areas. The questionnaire was answered by 41 Swedish municipalities. A handful of them were companies co-owned by a few municipalities. Only one out of four municipalities had source protection areas to all their Water sources and for many sources the protection was not satisfactory.

This project is focusing on a future park that will surround Hyllie Water tower in the outskirts of Malmö. The Water tower will be located in the central part of the new building area Hyllievång. The park will function as a town park with a special focus on Water. The Water council of the municipality, Va-verket, has for the last 7 years built up and been in charge for a pedagogical programme in the Water tower, were schoolchildren come to learn about the cycle of Water and how we use Water in our daily life. In the park they want to build a new part that gives experience of Water, as a compliment to the information in the tower. What will that park look like, and what shall it be constructed of? How do you bring Water to the surface in a park? How can landscape architecture work to enhance the presence of Water and make people more interested in Water issues? In the search to find the answers to all my questions I have meet with people, read books and visited different places.

Coastal areas are popular for housing, both for permanent living and holiday houses. At the same time, thin sediments and small storage capacity in the bedrock makes the ground Water resources limited. The limited ground Water resources combined with too large withdrawals of ground Water makes salt Water intrusion a problem in many coastal areas. This study examine the risk of salt Water intrusion in drinking Water supplying wells on the island Södra Finnö in S:t Anna archipelago, Östergötland, Sweden. A calculation of the relation between ground Water recharge and withdrawal is obtained to analyze the ground Water balance in the area.

The purpose of this study was to examine whether an inventory of the vegetation overgrowth could be used to indicate a locally nutritional impact. The study was conducted at Märstaån where the Water runs through a number of agricultural lands that could lead to an increased amount of diffuse emissions of nutrients. The vegetation overgrowth in the Water was also studied in relation to shade, meandering and Water flow effects on the vegetation. With this method, no definitive conclusions could be drawn.Where the Water was shaded, no vegetation overgrowth could be found. Therefor trees should be planted to prevent any future overgrowths.

In this report the importance of irrigation scheduling in dry climate is shown, how it can save Water and energy; how this method can improve crop yield by supplying the right amount of Water at the right time. It is shown how irrigation scheduling and irri-gation technology together increase the irrigation efficiency..

ABSTRACTThe aim of this study is to analyse if the UN today constructs the Water issue as a security issue and to argue about in which way the organization in that case does so alternatively why it can be said that the UN doesn?t construct the Water issue as a security issue.In order to reach this purpose the following questions will be answered:?Does the UN construct the Water issue as a security issue today?-If yes, in which way?-If no, why can it be said that the organisation doesn?t?The methods used are qualitative literature studies of policy documents on Water from the UN. The focus is to analyze the ideas about Water and to apply my theory on the concept of security, which is Barry Buzan?s framework on security, to these ideas.The main results showed that the UN strongly constructs the Water issue as an environmental security issue for environments and species and in relatively strong terms also constructs it as an environmental security issue for civilisations. In rare cases the organisation constructs it as a societal security issue, but the UN doesn?t construct the Water issue as a military, political or economic security issue..

Fresh Water has become more and more of a scarce commodity. Water scarcity isn't first and foremost a cause of drought and wasting, but a cause of inequality and mismanagement. This is not only a problem for developing countries, and there can also be variations within countries. The municipality of Gotland has a development program called Vision Gotland 2025, with goals for growth and sustainable development. The aim of this study is to examine whether the use and management of Water resources on Gotland and Vision Gotland 2025 is conformed to the Water Framework Directive and the Ecosystem Approach in terms of sustainability.

AbstractThis study deals with preschool children's ideas about Water in our body. Ten children with the age of four to five were interviewed individually, the interviews were qualitative. The children were also asked to draw their answers and answer questions about a picture that represented the excretory system. The results of my study show that children did not have any knowledge about the Water being vital for us. Preschool children had no knowledge of why it is important to drink Water.

This paper is intended to provide a picture of which associations Water can wake in the human mind from the perspectives of garden history as well as from that of environmental psychology. I hope to paint a fairly broad picture of our perception of Water that can serve as a basis for discussion and as a starting point for different forms of design work in landscape architecture. The historical perspective emphasizes the importance of Water as a condition for the emergence of gardens and in a wider perspective the importance of Water in early cultures. Also, I describe a picture of how Water has been used throughout the history of gardens from early Egypt to the baroque era. The garden history analyzed from an art historical perspective gives a picture of human associations to Water, and the history behind these associations is presented. As a compliment to the art history approach, I have chosen to highlight our associations with Water from the perspectives of environmental psychology and evolutionary science.

The Water company MittSverige Vatten (?MidSweden Water?) located in the Medelpad, Sweden was in need of a moreexclusive Water carafe for restaurants and conference in the region. Current design solution was not able to cope with thedemand of a more exclusive setting and was not promoting the company in a good way. In the beginning of the projectit became clear thru an intense interview period that there was at least three directions for design solutions the companycould go for.? A carafe (exclusive settings)? A pitcher (conference and lunch servings)? A Water dispenser type (serving of larger amounts of Water during a certain brief periods of time.)It was decided to go for the exclusive one.Small pieces of rock from the last ice age turned out to be a vital component of the new design concept for the company..

To guarantee protection of our drinking Water, Water catchment protections are established. These are divided into three different zones and in the first zone it is most likely that an activity, such as agriculture, will contaminate the Water resource. Hence the activities are strongly regulated or banned. The EU communion is working towards a sustained Water quality through several directives; Nitrate Directive, Waterframwork directives and Sustainable use of pesticide directive. The main purpose is to regulate the diffuse pollution from agriculture.This thesis is about how Denmark, Germany and France are working towards a sustainable agriculture within Water protection areas.

The discharge from Lake Mälaren is regulated to keep the lake Water level within limits set by a Water decree. Despite this, in the year 2000 the lake Water level rose above the upper limit. Studies conducted at the climate modeling unit Rossby Centre at the Swedish Meteorological and Hydrological Institute (SMHI) indicate that the inflow to the lake may increase in the future. A flood in the area will, among other things, strike infrastructure and residential districts.The aim of this study was to investigate the Water levels of Lake Mälaren in future climates. In addition to this possible future expansion of the lake discharge though the sluice gates in order to keep Water levels below limits set by the Water decree and to prevent flooding of the shoreline were discussed.
