Abstract [en]

The balance of the costs for capital, energy, maintenance and boundarylayer polymer injection is described in a model for life cycle cost assessmentsof pumping sewage sludges at a solids content (TS) in the range of15 to 35 %. A design tool for sludge pumping with solid contents of up to8 % is also described. Tests with centrifugal pumps for TS-values of up to10 % are presented.

Abstract [sv]

Kostnadsbalansen mellan kapital, energi, underhåll och glidfilminjicering av polymerer beskrivs i en livscykelbaserad modellansats för torrslamspumpning. Vidare beskrivs ett dimensioneringsverktyg för slampumpning vid torrsubstanshalter (TS) upp till 8 %. Tester med centrifugalpumpar för TS-halter upp mot 10 % presenteras.
