Återvinning av näringsämnen från hushållsspillvatten med omvänd osmos

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.

Digitala kläder? : En studie om traditionella klädföretags it-strategier 

This paper focuses on traditional clothing enterprise IT strategies. The purpose was to investigate the correlation between traditional clothing companies IT strategies and their brand. In a market where the competition is high it has become more important that the company targets a customer segment. To reach their targeted customers the company builds their brand with different corporate strategies. This segmentation is necessary because of the high exposure to competition, and a well-established brand could be a prerequisite for profitability.  In today?s market, IT has a major impact on the clothing business.

Empowerment : En studie om empowerments påverkan på frontpersonalen i tjänsteföretag.

This thesis is about how the front-staff in two service companies experience empowerment. Competition for business in today's society is becoming increasingly fierce, which means that they must find a way to differentiate themselves from competitors. Service has become a way to compete. Front-staff competence and ability to offer a good service is a crucial factor when the company's success is being measured.Empowerment in business is used as a tool to create motivation and satisfaction of individuals at work. Companies using empowerment can create the freedom and opportunities for employees to act at their own intelligence and discretion.

Europeiska mötesdestinationer : En jämförelsestudie om professionella möten & mötesindustrin i Stockholm, Warszawa & Rom

The meeting industry is a growing industry around the world, and the technological development in recent decades is one of the contributing factors to the increased travel opportunities and meeting industry's expansion. It can be assumed that the technology could replace some of the personal meetings, but humans have always had a need to meet in physical locations in work related purposes, therefore there is no evidence that personal meetings will disappear. Technological development should be seen as complementary rather than a substitute to the existing professional meetings. Public and private sectors within countries has drawn attention to meeting industry's potential, as favored destinations in terms of economic administration, image creation, expansion and acquisition of further market share in the global market. Meeting industry is complex precisely because there are so many different actors and stakeholders that integrate.

Dissekering av ett lokalsamhälle : En studie av sociokulturella mönster på småländsk landsbygd 1838-1845

Following essay examines the social and cultural patterns of southern rural Sweden between the years 1838-1845. The study is based on records from trials held by the district court of the district Norra Möre, which provides an insight to the everyday life in rural local community. Emphasis is put on exclusion and inclusion: the basis for community, codes for inclusion and exclusion, meaningful attributes, social and cultural capital etc. Questions concerning gender are raised as well as intents to discover whether modern ideas contrast early-modern, especially considering the process of individualization. Results show that concepts of confidence and trust were extremely valuable and possessed significant meanings.  Confidence, which established itself on virtuous and honest life, created the framework for most aspects of social society: for example credibility inside and outside of court, maintenance of friendship and company, capacity of upholding a working life. Forfeit of trust, through extensive dissolute, mischievous and ill-considered way of life meant exclusion from the community and great vulnerability.

Produktivitetsanalys ur ett LEAN-perspektiv : En studie hos OPPC, AstraZeneca

The objective of this thesis is to map the resources and methods used at the department OPPC, at AstraZeneca, and derived from that give suggestions on possible solutions that will increase their productivity.Mapping of the product flow, as well as gathering of process data, has mainly been done using observations, but consultation with the process technicians has also played a great role. Further have theoretical methods been used, based on literature studies, within the areas of Lean production and statistics.The work has incrementally gone forward since the steps taken has been restricted by the irregularity of production which led to the need of creating a fictive production flow. This has affected the lead-time calculations in the way that they are meant to give an indication, rather than an absolute truth, on how different methods described shall be used.The current state analysis showed multiple areas of improvement when defining capacity as value adding time in relation to total throughput time. Using the "standard scenario" as a basis showed that the actual production flow only constituted 50% of the total project time. Further it showed that the workflow contained more non-value adding activities than value adding activities, which is a result of how the work is distributed within the department as well as in the different projects.

Att ta vara på solens fulla uppvärmningskapacitet

The purpose of this bachelor´s report is to expand the knowledge about heat supply of a small house in Malmö. The heat supply will be provided from solar panels in combination to two accumulator tanks which will storage the up heated water and a pellet boiler.The technique used here is warmth storage in water over seasons, which will provide the total need of heating for the house. Accumulator tanks in combination to solar panels gets more and more common in Sweden but this far it´s unusual to use it for storage over seasons. This report will highlight many of the difficulties associated whit heat storage and give information about a system's possible design and function.The design of this system is decided early on. An accumulator tank is placed 2 meters down in the earth on the backside of the house.

Expansionsmaskiner istället för strypventiler - en effektivisering

In Uppsala CHP Plant, there are six pressure reducing valves to reduce the pressure from 15 to 3 bars, before six absorption heat pumps. During the process the energy is conserved but losses occur in form of exergy. The aim of this thesis is to reduce the losses of exergy. This can be done by letting turbines replace the pressure reducing valves.In this thesis an investigation has been done of the conditions today, the conditions after the change from pressure reducing valves to turbines and a comparison of three different types of turbine solutions. The three examined solutions are one turbine, several helical screw expanders and several small turbines in parallel with asynchronous generators.The six absorption heat pumps have been divided into two groups; one group of four and one group of two absorption heat pumps.

Utvärdering av möjligheten att tillvarata energi ur processvatten : En undersökning gjort vid Olofsfors AB på uppdrag av UMIA AB.

The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.

Konstruktion av värmespridare med grafit för flygelektronik

This master thesis was carried out for Saab Avitronics, a business unit of Saab ABactive in electronic systems for military aircrafts. Reliability and weight are of crucialimportance in this environment. To improve reliability and lower the weight graphitemay be used for electronics cooling. Graphite is an anisotropic material and hasthereof high thermal conductivity in two directions (in-plane) and a relatively lowconductivity in the third direction (through thickness).The purpose of this thesis was to investigate if graphite is an adequate thermalconductor to use in PCB carriers. The carriers support and cool the PCB by divertingthe heat dissipation from the PCB components to the edge.

Effekter av ökad internationell handel på kvinnor kontra män

In the light of ever increasing international trade around the globe, affecting men and women in all countries, it is surprising that so little attention is given its gender effects. The effects of trade are said to be gender neutral, but could potentially act reinforcing on the existing gender patterns in a society. The aim of this thesis is to examine whether the implications for men and women in relation to trade liberalization can be found to differ. By stylizing some differences between men and women, this is done by examining the theoretical implications mainly via the Heckscher-Ohlin model and through a Beckerian approach. The implications found are then compared with the findings in existing empirical work.

Analys av verkstadsplaneringen : på Fläkt Woods i Jönköping

This paper is finishing part of the two-year master programme in Industrial Engineering and Management.Initially there was an inquiry of studying the queue-times that Fläkt Woods uses when they break down internal working orders. These times were assumed to be too generalised and does not apply to the actual value of the queue-times which generates incorrect data and delivery delays. During the work of this paper it has been established that it is not the queue-times that is the biggest problem. The problem is the shop floor control and the lack of manufacturing the right products at the right time. Therefore an analysis of the production planning process was made to bring forward the real problems.

Uppgradering av automatisk teststation

The climate changes that are occuring in the world have resulted in that the EU callingfor a 20 % reduction in energy consumption to the year 2020, to reach that goal theEU want the public sector to go forth as a good example. Västfastigheter owns andmanage the hospital buildings in the Västra Götaland region. To be able to reducetheir energy usage Västfastigheter has hired several consulting firms to chart out theenergy consumption on each hospital building. The biggest energy savings potentialhave been calculated and what the cost will be to perform each action. The energyaudit have been completed and stand as the decision basis for Västfastigheter?s choiceon which action packages that should be implemented.

Beräkning av pumpkapacitet samt konstruktion av pumpfundament

Ett undersöknings- och utvecklingsarbete för att lösa ett problem med att dränkbara pumpar i ett vattenavrinningssystem gick sönder med perioder på två år i genomsnitt, utfördes i samarbete med Cementa AB i Skövde. Orsak till pumpars haveri söktes och fanns vara bristande rutiner och kunskap om det underhåll pumparna krävde. För att lösa detta problem utvecklades riktlinjer för nyinköp av torruppställda pumpar för att möjliggöra kontinuerligt underhåll. Då möjligheter för placering av torruppställd pump saknades utvecklades ett pumpfundament för placering av torruppställd pump. Krav för utvecklingsarbetet togs fram i samarbete med Cementas underhållsavdelning och teoretisk dimensionering av dränkbara länspumpars dåvarande volymflödeskapacitet utfördes.
