This poster paper presents information on a small system pilot study for iron and manganese removal. The scope of the pilot study included: a review of oxidation alternatives including aeration, chlorination, permanganate, and detention; a review of filtration alternatives including four medias, greensand, treated dual media, manufactured greensand, pyrolusite, and filtration rates and filter run times; a review of residuals production including backwash rates, backwash duration, and settleability; a review of water stability including pre-filter tendency for scaling, and post-filter corrosivity. The presentation provides treated water results, filter media characteristics, and pilot study results. Includes tables, figures.
