Fosforavskiljning i reaktiva filter vid småskalig avloppsrening

An excessive input of nutrients to lakes and other water bodies has created a problem with eutrophication in Sweden. Untreated, or partially treated, domestic sewage is a major source for discharge of phosphorus (P), which is the nutrient most frequently responsible for eutrophication of most Fresh waters and the Baltic Sea. The waste water can be cleaned by filter materials, which have a high P-retention ability and which after saturation may be used as fertilizers. Four potentially suitable filter materials were tested in batch- and column experiments in this study. In the batch experiments, the following materials were shaken with waste water in time series ranging from 5 seconds to 60 minutes: coarse (1-4 mm) and fine (0-2 mm) Polonite® (heated bedrock from Poland); Filtralite® (light expanded clay aggregates with limestone added before burning); water cooled blast furnace slag (BF-slag) and BF-slag mixed with 10% burned limestone.

Mjölkningsfrekvensens påverkan på mjölkproteinets sammansättning och kvalitet :

In modern dairy production the milking frequency is increased in some herds due to introducing of automatic milking systems or the farmers decision to milk high producing dairy cows more than two times a day. With more frequent milkings the milk yield increases while the content of fat and protein decreases. However, how the composition of protein is influenced is not fully evaluated. The purpose of this study was therefore to see if a higher milking frequency had any impact on the milk production and especially on the protein composition. This study was conducted as a half udder experiment.

Sortimentsinriktad avverkning

Forest enterprises have always searched for ways to improve efficiency. For the past few years there has been an emphasis on stock-keeping levels. Increased demand for Fresh round timber and the need to decrease the amount of tied-up capital has made the forest industry reduce its inventory levels. This has brought on a higher demand on the timber supply from the forest management districts concerning both delivery in time and assortment output. As a result, the flow of timber has fluctuated a lot with serious consequence for the timber supply during 1994.

Kvarteret Veiberg : från sluten innergård till öppen mötesplats

The object of the thesis is to propose a new design for the neighbourhood of Veiberg that is situated in the small Norwegian town Jessheim. My approach was to first make an analysis of the whole community and the structure of the town, and then gradually focus on the actual neighbourhood to continue the research there. On the basis of my research the block will be redesigned. The research will lead to a well-planned design of the neighbourhood, which will adapt it to its surroundings in a sustainable and constructive way. The project will lead you through the history of the town and the intentions and aims of the municipality. The project also examines the structure of the town and the function of the neighbourhood in the town today as well as investigation of the history, the structure and the qualities in the area.

Bevattning av lagrat virke vid svensk skogsindustri : omfattning och miljökonsekvenser

Most of the saw and pulp industries have stored wood nearby their production, the main reason is to have a continuous wood flow to the production. Wet storage of wood is of great importance to keep the wood quality. Without water sprinkling the risk of drying outand decomposition through biological activity increases significantly and will result in a negative effect on future production and quality. One drawback of wet storage of wood is the leaching of chemical substances into the surrounding recipient. The log yard run-off contains phosphorus, nitrogen, phenols and organic substances. These substances can cause problems for the surrounding environment. The main objective of this project is to gain an understanding of the wet storage used by the Swedish wood industry and estimate the environmental consequences that run-off water will have on the recipient.

Individers upplevelse av att bo och leva i bostadsomra?det Kronoparken

This is a qualitative study made to find out individuals experience of life in the residential Kronoparken in Karlstad. The study is a part of a municipality supported project aiming to find points of improvement and work for the area's development. This study is a first step to hear in what way the residents themselves describe their neighborhood and their lives. A total of thirteen people participated in focus groups with semi-structured interviews as data collection and the study was based on an availability sample which in this case meant that citizens of the residential Kronoparken were asked to participate. Data were analyzed through thematic analysis and in the analysis three themes appeared that summed up what the participants talk about and emphasized most: a divided area, anticipation and valuation as well as a comfortable and healthy every day living.

Delta X : Utveckling av värmeväxlare

Stockholms vattenskärning AB in Kungsängen has through the acquisition of a company begun to design and produce aircraft heaters whose origin is early 1970s which follows a high inefficiency in terms of energy consumption and size.The aircraft heater, which is sold worldwide, serves its purpose for customer satisfaction and has done so ever since it was developed in the 70s.Stockholms vattenskärning AB is now investigating the possibility in making the aircraft heaters more efficient, both in terms of energy consumption but also on a more efficient design with the belief that it would lead them to an edge in the market. The aircraft heater consists of several main components whose function altogether is to keep passenger aircrafts warm while they are on the ground.This project has been limited to the further development of the heat exchanger package which accounts for the conversion of the hot medium to the Fresh air being carried in to the aircraft cabin. Work has been divided into different phases in order to create a better understanding of the project range and to make it easier to divide the various elements in the time available, 10 weeks. These phases are literature review, situation analysis, concept generation, CAD, concept comparison and writing reports.After the initial literature review was made, a fundamental theory was written which is essential in understanding the remaining parts of the project.With the theoretical part as support, measurements and calculations were made on the current heat exchange package in a situation analysis to ensure its operation and efficiency.In the concept generation phase, the collected facts from the literature review was used as the basis for creating a matrix. The purpose of the matrix was to indicate the two most suitable types of heat exchangers to develop four new concepts out of.In the CAD phase the four concepts was drawn up and then described with text and images.The last phase is the concept comparison where a concept selection matrix is used to function as a decision basis for further production at Stockholms vattenskärning AB. The four concepts have been developed based on the current heat exchanger and is gradually changed into a design of a cross-flow heat exchanger constructed out of stainless sections. The purpose of this is to have gradual upgrading of the heat exchanger as an option, in order not to saturate the market..

Hållbar vattenförsörjning i områden med vattenbrist : Sustainable water supply solutions for areas affected by water shortage

In some coastal areas in Sweden water shortage sometimes appears because the withdrawal of groundwater is greater than the groundwater recharge. It creates a situation where the available groundwater is insufficient to support residents and businesses with drinking water. The high withdrawal of groundwater also creates a risk for saltwater intrusion to drinking water wells. The problem most commonly occurs during the summer when the groundwater recharge is low, but the population is high, due to tourism and summer residents.The purpose of this study was to investigate how local water supply in areas affected by water shortage can be solved as sustainable as possible. The work was divided into three parts where the first part comprised of a literature review on water systems in which four different options were investigated: artificial groundwater recharge, rainwater harvesting, desalination and water reuse.

Vaselin som kontroll vid försök med 1 % väteperoxidkräm i färska hudsår på häst

Wounds on horses are common and sometimes difficult to treat. The wounds are often big and could be discovered too late for primary sutures, which have to be applied within 8 hours from time of accident, before bacteria has been able to infiltrate the surrounding tissue. The healing is often complicated by delayed healing and wound infection with consequences like phlegmone, fistulation and proud flesh formation.To avoid these consequences, the traditional practice has been to administer systemic antibiotics alone, systemic antibiotics in combination with topical antibiotics or topical antibiotics alone. Because few antibiotics can be used in horses, is it important to household with the few substances that are available. In veterinary medicine today, the increasing resistance amongst pathogenic microbes such as MRSA presents a growing problem.
