bestämning av flödesvägar och åtgärdsförslag för optimal fosforbindning vid avloppsrening med reaktiva filter
… good phosphorus binding capacity. To test blast furnace slag as a reactive filter media for phosphorus separation in a full scale experiment, a wastewater treatment plant has been built behind the picnic area at Ångersjön alongside the road E4 in central-eastern Sweden. The …
… technique for removing uranium from drinking water is adsorption to reactive filter materials. Reactive filters represent a kind of low-cost technology that is intended to utilise a minimum of energy and chemicals. The filters may have specific physical and chemical properties …
IIR-filter är överlägsna traditionellt skapade FIR-filter på många punkter. De klarar sig med en klart lägre ordning för att realisera ett filter med samma egenskaper. En nackdel är däremot att filtret är klart känsligare för koefficient kvantisering och förlorar sina egenskaper …

test av olika filtertekniker avsedda för enskilda brunnar
… of this master’s thesis is to test some of the current commercially available filter techniques that are used to remove As from ground water. In addition, the national geographic distribution of arsenic and factors governing that distribution are discussed. Experiments regarding …
algoritmutvärdering och implementationsförslag
I den här rapporten utvärderas ett antal olika collaborative filtering algoritmer för att ta reda på vilken av dess som lämpar sig bäst för att implementera åt PlanEatSmile i en PHP/MySQL-miljö. Målet är att hitta en algoritm som klarar av att skapa rekommendationer i realtid …
… department is the final step in the chemical recycling unit. There, the filtered green liquor is mixed with lime to recover the cooking chemicals used in the pulp factory. The cooking liquid is called white liquor. As a residue from the recycling of the white liquor you get lime …
… contains biodegradable materials, which are often measured as BOD7. Trickling filters are sometimes used as a purification step for BOD-reduction. A trickling filter is a tower, which is filled with a carrier material. Microorganisms grow on the carrier material in the form of a …
fallstudie i Värmdö kommun
… They include three systems that are being used today in Värmdö community; Sand filter systems, Local waste water treatment plant and Conection to large scale waste water treatment plant. Three other systems considered to have a good purifying potential have also been studied …
en utredning om utsläpp av fenolföreningar samt metallsorption
The filters used today to purify water are often expensive and the need to find new filter materials is substantial. Studies of pine bark have shown that this is a material that may be used as an alternative to conventional filter materials, such as activated carbon. However …
Simulations of simulink models using Kalman filters are often very time-consuming. This problem depends mainly on the fact that the Kalman correction has to be performed at each sample instance through the whole simulation. The goal for this thesis work is to reduce that …
En undersökning av reningseffekt med avseende på järn och mangan
… The aimwith the project is to investigate the purifying effect of percolation filter due to iron andmanganese. The overall goal was to investigate how the parameters surface load,sandfractions, and burden time affect the purifying effect. The expectation is to optimize thedesign …
… The purpose of this thesis was to collect isocyanates in air with impinger-filter samplers and solvent free samplers. Furthermore the isocyanates were to be analyzed with liquid chromatography-mass spectrometry. The solvent free sampler consists of a polypropylene tube and …
<em>En studie om hur män och kvinnor skildras i samhällsmagasinen Filter och Fokus</em>
