Assessing the partitioning of pharmaceuticals and personal care products in secondary wastewater treatment and fate to the receiving environments
… in liquid and solid streams in a conventional secondary wastewater treatment plant and compared to predicted partition loadings and toxicity levels. The predicted partitioned loadings derived from the model were significantly different from partitioned loadings within the treatment plant. …

The capacity of native fish and a freshwater mussel species to control suspended solids in wastewater stabilization ponds
Stocking herbivorous aquatic organisms in wastewater treatment ponds specifically to control phytoplankton biomass and reduce suspended solids can provide small, rural communities with inexpensive, secondary wastewater treatment. The capability of several native fish species and the freshwater …

The operation of a completely mixed activated sludge pilot plant employing alum addition for phosphorus removal
… surface waters has created a need to upgrade wastewater treatment processes. New treatment objectives, in general, relate to the removal of phosphorus, achieving nitrification, and essentially eliminating the carbonaceous oxygen demand of wastewaters prior to discharge. The objective of this …
