An innovative new treatment system has been designed and constructed for the lower discharge of Saxman Run. The treatment system uses the activated iron sludge (AIS) process in a sequencing batch reactor (SBR). In this process the iron oxide sludge produced during remediation is used as catalyst the oxidation of Fe+2. The treatment system has been in operation for about two years, and is capable of remediation about 40 GPM of flow in a 10,000-gallon reactor. We will discuss the performance of the reactor, and its ability to treat acidic waters using alkaline additions directly into the treatment reactor. Economics of direct addition of alkalinity versus installation of an ALD will be compared.



Daryle Fish is Assistant Professor of polymer and inorganic chemistry at St. Vincent College in Latrobe, PA. He received B.S., M.S., and Ph.D. degrees from the State University of New York. His research interests include new ways of synthesizing plastics and space aged materials and controlling their physical properties. His research also includes environmental chemistry of iron compounds as it relates to remediation of mine drainage. His work also focuses on passing on skills to students with one-on-one and small group research projects. He enjoys playing with his two sons, fly fishing, and gardening.
