a feasibility study
… build aprocessing plant that will segregate the waste into recyclable, inert, organic and burnablematerial. The inert and organic waste will be processed further into bricks and compost,which will be sold on the open market. The burnable material will be processed into a …
jämförelse av befintlig pastörisering med integrerad termofil hygienisering på Kungsängens gårds biogasanläggning i Uppsala
… owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion all substrate is sanitized by one …

undersökning av fosforhalter
… also show that much of the measured phosphorus is bound to particles or organic material. 3. Is the soil type the reason why the phosphorus level vary within the catchment? This was one of the first questions that came up when the project started. But due to lack of data, a …
soil carbon and yield modelling for crop rotations with rye
… term biogas digestate refers (in this case) to the slurry that remains after organic material, primarily food waste or animal manure, has been used for biogas production. For rotations with ley, a case where ley was used for biogas production and the resulting digestate was …
litteraturstudie om reningsmetoder samt pilotförsök med jonbytesteknik
… in water chemistry between the two locations was the amount of dissolved organic matter (DOM). There seemed to be an inverse relationship between the concentration of DOM and the capacity of the resin. This indicates that the chemistry of the untreated water is of great …
generell beskrivning, förekomst av traktorspår samt kvicksilverhalter i körpåverkat ytvatten
… the stream. Machine tracks that enter the stream can increase the amounts of organic and inorganic material transported to the stream. The aim of this thesis was to collect the general characteristics of the riparian zones along small forest streams of first order in Värmland …
en jämförelse av klor och UV-ljus
… is the production of unwanted by-products when the free chlorine reacts with organic matter. These by-products, e.g. trihalomethans, THM, have shown to bee carcinogenic. This was one of the reasons that contributed to the changeover to disinfection with UV-light, at one of the …
en studie utförd vid Hovgårdens avfallsanläggning i Uppsala
… the municipality of Uppsala needs improved knowledge of the contents, mostly organic compounds in the leachate and they also want to find a method to minimize the emissions of these compounds. The purpose of this study was to find a practical and economical method based on …
… related studies of BOD show that the microorganisms need five days to degrade organic material and the hydraulic retention time in the aerated lagoon has to be guaranteed.
… control for sodium hydroxide was examined. The leachate had a small content of organic matter and nutrients, but had a large content of halogenated substances (AOX) and the heavy metals nickel and copper. High concentrations of contaminants were reduced better than low …
test av olika filtertekniker avsedda för enskilda brunnar
… total concentration of As and other elements forming oxyanions, dissolved organic carbon (DOC) and pH. Silica (H2SiO40) can compete with arsenic for adsorption sites in filters based on metal (hydr)oxides. Sulphate (SO42-) can be a competitor through anion exchange in filters …
… organs from bumps and punches. Fat is insoluble in water but soluble in organic solvents. The properties of a fat depend on its structure. The most common fat in human food is triacylglycerides. Linolic acid and linoleic acid are the essential fatty acids and have to be …
En litteraturstudie och rötning i labbskala
… Analyses of gas production, gas composition, content of dry matter and organic matter, carbon / nitrogen-ratio and pH have been performed.The results from lab scale digestion show that the pea residue has a methane potential of 300-400 liters of methane per kg VS during 25 days …
… 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 …
