Study of Pilot-scale Filtration at Minneapolis Water Works

Abstract

Minneapolis Water Works (MWW) in Minnesota, United States, have experienced occasional taste and odor episodes with their river water source. This thesis investigates the potential benefits of installing granular activated carbon (GAC) filters at MWW, replacing existing anthracite medium filters and eliminating the need for powdered activated carbon as taste and odor protection. Pilot scale filters of GAC and anthracite media have been studied and batch reactor tests have been performed projecting the potential filtration and sorption capacity of GAC filters at MWW.
