Per- and Polyfluoroalkyl Substances in Toilet Paper and the Impact on Wastewater Systems

Environmental Science & Technology Letters, Journal Year: 2023, Volume and Issue: 10(3), P. 234 - 239

Published: March 1, 2023

Here, we evaluate a perhaps unexpected contributor of per- and polyfluoroalkyl substances (PFAS) to our wastewater, an input anticipated at every wastewater treatment facility─toilet paper. In this study, both toilet paper sludge were characterized explore the magnitude potential PFAS loading into systems from sludge, 6:2 fluorotelomer phosphate diester (6:2 diPAP) was most prevalent detected, usage estimated contribute 6.4 80 μg/person-year diPAP wastewater–water systems. Our results suggest that should be considered as potentially major source entering

Evaluation of Per- and Polyfluoroalkyl Substances Leaching from Biosolids and Mitigation Potential of Biochar through Undisturbed Soil Columns

ACS ES&T Water, Journal Year: 2024, Volume and Issue: 4(2), P. 413 - 426

Published: Jan. 25, 2024

Land application of biosolids recycles nutrients and reduces the need for commercial fertilizers. However, per- polyfluoroalkyl substances (PFAS) may leach from biosolids, resulting in groundwater contamination. We measured PFAS leaching land-applied through undisturbed soil column trials evaluated treatment potential amending with biochar. Synthetic rainfall was applied weekly to columns four regions Wisconsin, including two fields a history biosolid application, simulating annual precipitation. The treatments consisted control (soil only), amended receiving mixture Concentrations total leachate were significantly affected by location site One-time result contamination, as concentrations exceeded local standard (a combined perfluorooctanoic acid perfluorooctanesulfonic concentration 20 ng L–1) at three locations. Legacy pose risk human health years after an intensive standards.

Biochar facilitate sustainable use mitigation long-chain leaching, pending long-term field evaluation.

Current understanding on the transformation and fate of per- and polyfluoroalkyl substances before, during, and after thermal treatment of biosolids

Biosolids (stabilised sewage sludge) are the final solid residues of wastewater treatment process and generally applied on agricultural land in many countries, including Australia. Per- polyfluoroalkyl substances (PFAS) a group synthetic fluorinated chemicals with ubiquitous applications consumer products persist environment. Globally, PFAS have been detected biosolids considered source discharge to The thermal is gaining increasing interest water sector. Therefore, viability techniques for safe destruction has received substantial research attention last few years. Recent studies suggest that can be removed potentially destroyed during combustive (such as incineration) non-combustive treatment, such pyrolysis, gasification, hydrothermal carbonisation/liquefaction. However, there limited understanding fate transformation degradation across overall from feed pre-treatment gas cleaning (post-thermal treatment) stage. This review consolidates current knowledge transformation, destruction, before, during, after biosolids, covering lab, pilot scale, industrial studies. It suggested mechanisms may differ established pathways pure salts, given complex organic inorganic matrix typically low concentrations. Among all techniques, pyrolysis extensive investigations at different scales operation. temperatures residence time need sufficiently optimised designing realistic large-scale systems relevant biosolids' compositional peculiarities destruction.
