Abstract
Like many other municipal wastewater treatment facilities, the South Shore Wastewater Treatment Plant (SSWWTP) utilizes the addition of iron solution for the removal of phosphorus. The addition of iron to the wastewater treatment process results in the precipitation of inorganic phosphorus compounds, permitting the plant to meet its Wisconsin Pollution Discharge Elimination System (WPDES) effluent requirement of 1mg/L total phosphorus. Traditionally iron solution has been added to the raw plant wastewater stream as pickle liquor. Pickle liquor is a waste product from the manufacturing of steel products, consisting of about 7 percent sulfuric acid with dissolved ferrous sulfate or ferrous chloride. Pickle liquor has been the preferred product for removal of phosphorus due to its availability and low cost. However, recent reduction in pickle liquor availability has necessitated the use of ferric chloride as an alternative iron source. The increased costs of phosphorus removal, as a result of ferric chloride addition, led to an evaluation of biological phosphorus removal (BPR) and chemical optimization at the SSWWTP.
