Project goals and concerns for each site are provided, along with biological treatment challenges, Pilot Testing Overview for individual sites, and cost savings. Presentation conclusions for biological iron and manganese filtration indicate that:it provides a cost effective alternative totraditional oxidation-adsorption or oxidation-precipitation-filtration treatment in systemswith high iron and manganese levels;it greatly reduces the need for chemicals andoperating costs; and,it provides a safe alternative in situationswhere chlorine exposure is not acceptable. Includes figures.
