myllning och surgörning som metoder för att minska avgång vid spridning
… used by the crop. The focus of this study has been emissions from spreading slurry where the loss can vary widely depending on slurry-, soil-, and weather conditions. There are mainly two different ways to reduce the emissions. One is to inject or mix the slurry into the ground …
evaluation of methods, microbial activity and agronomic implications
… traits of four different BR and to find a viable procedure for evaluating slurry fertilizers. Two experiments where soil respiration and soil potential denitrification activity (PDA) was measured at fertilizer addition were performed. As controls pig slurry (PS) was used in both …
… different suspended solid concentrations(8%, 10% and 12%) of pretreated birch slurry which contained 16 % total suspended solids.Two different hexose fermenting yeast strain (Ethanol Red) and pentose fermenting yeaststrain were used.Quantifying the concentration of chemical …
… conditions with a retention time of 20 days. Screw crush technique gave a slurry with a methane yield of about 440-490 mL / g VS, which was slightly higher than the yield of 300-350 mL / g VS from the slurry pretreated with Food Waste Mill. The methane concentration was slightly …
… in the incubation for four organic fertilisers: chicken manure, cattle slurry, Biofer (bonemeal) and Vinasse (waste product from the yeast industry). The objective was to evaluate whether these methods could reliably predict mineralization under field conditions. Incubation …
Metoder för slurrytillverkning
… AB, Händelöverket in Norrköping. The report shows methods to manufacture slurry consisting of fly ash and water. The slurry shall be pumped into several former oil storage rock shelters that E.ON has put into operation for the specific purpose. The ash mixture also develops …
The influence of calcium and magnesium on the expellation of arsenic in the fluidized bed furnace
… with high arsenic levels in the fluidized bed furnace, the addition of slurry from the lead kaldo furnace should be avoided. The slurry, which is normally added during roasting, contains large amounts of calcium oxide which has proven to be an inhibitor of the expellation of …
… processes of nitrogen were studied in an incubation experiment. Cattle slurry and broiler litter were placed in the soil with three procedures for incorporation including placement on top of the soil (TOP), in the middle of the soil (MID) and mixed homogenously with the soil …
planering för om-, till- och nybyggnad
… The milking parlour is of the type ”tandem” and the manure is handled as slurry. In booth solutions, the working hours and the work tasks whit high work load are minimized. The cost for the first solution comes down to 46,137 SEK per cow and for the second solution 75,062 SEK …
… läge. Slutet läge innebär att utrymmet framför borrhuvudet trycksätts av en slurryblandning med åtta bars mottryck som begränsar vatteninläckaget samt stabiliserar fronten. Även förbehandling av bergmassan genom skölden eller genom borrhuvudet är möjlig för att begränsa …
… retained by tailings dams. The objective of tailings dams is to retain the slurry from the mining process and in that way prevent spill into the surroundings that might be harmful for the environment. Tailings dams are often constructed as staged embankments so that construction …
… kan användas i stabiliseringssyften är osläckt kalk, släckt kalk, samt kalk i slurryform. Reaktionen mellan kalk och jord sker i två huvudsakliga steg, modifiering som följs av stabilisering. I modifieringsfasen byts de kalium- och natriumjoner som normalt sett är bundna till …
… the forage was above what is recommended. The majority of the farmers spread slurry as manure on their fields. Most of them wilted their herbage before loading and about one third had engaged a machine station to help them with their harvest. Many of those in the group that had …
provtagning, analys och förslag till åtgärder
… of the pit lake. One suggested measure against high acidity is to inject a slurry of reactive lime stone and sewage sludge into the waste rock dump. This should increase the pH and facilitate reducing conditions, which should keep the heavy metals in precipitated metal …
kartläggning, analys och åtgärder
… och är en del av affärsområdet Minerals. Verksamheten i Sala tillverkar slurrypumpar samt processmaskiner och är en stor leverantör av pumpar till mineral och processindustrin. Målet för examensarbetet var att kartlägga och analysera ledtiden samt att hitta lösningar och mätetal …
