Pilot-Scale Evaluation of Microfiltration/Ultrafiltration, Ozone, and GAC for Arsenic, Taste and Odor Control, and DBP Precursor Removal in a Southwest Surface Water
西南地表水中微滤/超滤、臭氧和GAC对砷、味道和气味控制以及DBP前体去除的中试评估
This paper summarizes the results of a 6-month pilot-scale evaluation of microfiltration/ultrafiltration, ozone, and granular activated carbon (GAC) for arsenic, taste and odor (T&O) control, and precursor removal for the City of Scottsdale's future Salt River Project (SRP) water treatment plant. Membrane filtration with in-line ferric sulfate coagulation followed by GAC contacting achieved the water quality and operational goals of the City. Ozone oxidation was not deemed necessary for the full-scale design. Includes 2 references, tables, figures.
