TL;DR: In this article, the authors investigated the removal of silver in five publicly owned treatment works (POTWs) and the fate of Ag in effluent receiving streams, finding that the percentage of total Ag removed was independent of the influent Ag concentration.
Abstract: We investigated the removal of silver in five publicly owned treatment works (POTWs) and the fate of Ag in effluent receiving streams. Comparisons were made to several other metals. Silver was removed efficiently (>94%) in all POTWs. The percentage of total Ag removed was independent of the influent Ag concentration, while the concentration of Ag in effluents was directly related to influent concentration. A good correlation (r 2 =0.77) between metal removal (%) and partition coefficient (K d ) indicated that differences among metals in removal efficiency were controlled mainly by metal partitioning (sorption) to particles removed by settling and/or filtration. A large fraction (19-53%) of Ag in the filterable ( 0.05 μm), and the percentage filterable Ag was directly related to DOC concentration (r 2 =0.96). Effluent Ag concentrations (0.06-2.6 μg/L) were several orders of magnitude higher that typical background stream levels (1-2 ng/L), but Ag discharged to streams was rapidly dissipated by dilution and incorporation into stream sediments.

TL;DR: Most target PhACs were not completely removed before discharge into Lake Pontchartrain, although their collective annual loading was reduced to less than 1kg and down to ppb with significant potential for dilution in the large lake.

TL;DR: The results indicate that functionally stable wastewater treatment bioreactors have stable microbial community structures under normal operating conditions but are able to adapt in response to perturbations to sustain high effluent quality.

TL;DR: Three aquatic plants Eichhornia crassipes, Lemna minor and Spirodela polyrhhiza were used in laboratory for the removal of heavy metals from the coal mining effluent and analysis results showed that plant roots have accumulated heavy metals approximately 10 times of its initial concentration.
