Title: Successful mercury reduction in pilot study at Seminole (Golder presentation at EUEC)

Summary: Pilot testing successfully reduced effluent Mercury concentrations to < 225 ng/l. Pilot influent concentrations were lower than historical maximums. Pilot test process reduced effluent Mercury to < 40 ng/l after flocculation and settling unit operations were improved. Results obtained in October 2014 (higher effluent Mercury) need further review (ratio of organosulfide:ferric iron may be a key). Substantial colloidal fraction of Mercury was present. Effective chemical addition, flocculation and settling are necessary so that sand filters (current Seminole polishing process) can be utilized. Tighter membrane filtration might be needed.
