en studie med flödesproportionell provtagning
Dagvatten kallas det regn- och smältvatten som rinner av från hårdgjorda ytor i stadsmiljön. Detta vatten för ofta med sig stora mängder av föroreningar som tungmetaller, näringsämnen och oljerelaterade ämnen, vilka kan göra stor skada om de når recipienter. För att rena …

… are: energy consumption, waste production, greenhouse gas emissions and nitrogen oxide emissions. Suggestions for companies regarding the practical work with these environmental aspects are to focus on BREEAM and to use available product databases such as BASTA, SundaHus and …
Membrane bioreactors- A future solution at Lundåkra wastewater treatment plant?
… The nutrient removal in the MBR-solution was decreased or unchanged for nitrogen-, phosphorous- and organic parameters. However, the energy demand will increase with an estimated cost of approximately 1 million SEK annually. Moreover, the extra chemical consumption is estimated …
… products and has a crucial role in the final quality. Excluding non-protein nitrogen, bovine milk contains about 3.3% protein whereas about 80% of this fraction consists of casein. There are four major members in the casein family: ?s1-casein, ?s2- casein, ?-casein and ?-casein …
Dietrekonstruktioner genom analys av stabila isotoper på tidigmedeltida skelett från Rambodal, Styrstad Sn, Östergötland
Dietary patterns has varied throughout history, both due to resource and cultural limitations. In this thesis, a study was conducted to establish the dietary patterns of eight individuals from an early Midieaval gravesite in Rambodal, Östergötland, in order to explain why they …
… 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 …
Utvärdering av nuvarande reningseffekt och simulering av mängden bildat lakvatten under 2000-talets klimatförändringar
… model. The treatment system has the ability of reducing manganese by 90 %, nitrogen by 73 % och TOC by 79 %. By the turn of this century the amount of precipitation that percolates the waste at Degermyran will be between 254 and 298 mm, depending on the amount of greenhouse …

… shows that comfrey liquid is not sufficient as a total fertilizer. The low nitrogen content makes it less suitable for organic transplant production. However, comfrey liquid can be used in fruit setting crops as tomatoes, peppers and cucumber, from the time of flowering, as it …
biobränslets och askans innehåll av tungmetaller relaterat till markernas geokemi
… Jämtland are mainly the area around the lake Storsjön. There, the content of nitrogen in the soil is high enough to allow an increase in tree growth after ash supply. A lot of biofuels are taken out from cuttings there too. This study demonstrates that minerogenic material that …
… Another factor that surely improved the yield in pig-tilled treatment was the nitrogen effect of the animal’s manure. With a slightly different experimental setup, larger differences between the pig-tilled small plots would probably be shown in the results.
… potatoes. Potato is a crop that requires a good access to water and nutrient. Nitrogen is the nutrient that has the greatest impact on the specific gravity, quality and yield of potato crop. The specific gravity is closely liked to the maturation of the potato plant. The results …
