Igensättning av långsamfilter i Östby vattenverk i Kramfors

studie av påverkande faktorer

Examensarbete, avancerad nivå · Uppsala universitet

… bed increases with time after a cleaning. This indicates an accumulation of particles which increases with the load. Observations of the filter surface before cleaning showed that it was covered by a brown, jelly-like film. The internal resistance in the filter beds increases …

Rening av avloppsvatten efter skärprocess

Kandidatuppsats · Blekinge Tekniska Högskola

… far larger applications. As the process water contains quite large amount of particles, it is necessary to perform the filtration in different steps. The process water purifier is therefore composed of a module of coarse filtration and one of micro filtration. In the module of …

Navigering, sensorfusion och styrning för autonom markfarkost

Examensarbete, grundnivå · Linköpings universitet

… with Kalman filtering using an error model and the other is a centralized particle filter using an all-embracing model of the vehicle. The two methods have been evaluated and compared. Test results show that the two methods perform equivalently. The autonomous travel is …

Induktiv provning av ferritiskt rostfritt stå

Masteruppsats · Högskolan Dalarna
