Pharmaceuticals and personal care products are increasingly being detected in the environment and little is known of the effects to the environment. Thirty pharmaceuticals and personal care products were measured 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. Concentrations discharged from the treatment plant were below predicted and known toxicity levels for aquatic and terrestrial receiving environments. Together, these findings suggest the estimation model is ineffective for predicting partitioning loadings in secondary treatment, concentrations are not likely to be toxic in the marine environment around the outfall, and secondary wastewater treatment does have a positive impact on the removal of pharmaceuticals and personal care products during secondary wastewater treatment.

An evaluation of wastewater treatment technologies for the purpose of recirculation in aquaculture facilities with a focus on an unsubmerged bioreactor Collins, Stephanie Lorraine (2017-07-14)As aquaculture continues to grow worldwide, land-based aquaculture facilities can be ideal because a large volume of fish can be produced in a small area. With growth comes the concern of water usage and wastewater management. ...
