This powerpoint presentation presents three different project locations where issues with iron and manganese are not solved with traditional oxidation-adsorption or oxidation-precipitation-
filtration treatment. The locations include: Arugum Bay Water Supply Project, Sri Lanka, US AID -- Sri Lanka Tsunami Reconstruction
Program;
Jefferson County, Washington,
PUD No. 1 of Jefferson County -- Sparling Well
WTP Upgrade; and,
Fairbanks, Alaska,
Alaska Department of Fish and Game -- Ruth
Burnett Sport Fish Hatchery Influent Treatment. 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 to
traditional oxidation-adsorption or oxidation-precipitation-
filtration treatment in systems
with high iron and manganese levels;
it greatly reduces the need for chemicals and
operating costs; and,
it provides a safe alternative in situations
where chlorine exposure is not acceptable. Includes figures.
