Abstract
Wastewater from a U.S. research pharmaceutical facility with a large contribution from sanitary wastewater of animal and human origin was treated at a conventional activated sludge plant. The plant utilized the addition of ferric chloride to the primary clarifier for phosphorus control followed by extended aeration, sand filtration and chlorine disinfection prior to discharge to a stream (see Figure 1). The key discharge permit conditions included stanpliance. The paper reports on results of the investigation into causes of the poor UV performance.
