  • Which electrochemical processes are used in wastewater treatment?
  • Popular electrochemical processes include electrocoagulation, electroflotation, electrodialysis, electrolysis, electrochemical oxidation, electro-Fenton, etc. However, to apply these electrochemical methods to a large scale, more research is required. The following section summarized recent research on electrochemical treatment of wastewater.
  • Can persulfate irradiation be used to treat saline petrochemical wastewater?
  • Ahmadi, Haghighifard, Soltani, Tobeishi, and Jorfi ( 2019) explored an integration process of persulfate and ultrasonic (US) irradiation with EF. Results showed that persulfate-added EF (PUEF) was a promising technology for treatment of saline petrochemical wastewater, whose aromatic pollutants were degraded to simpler and aliphatic molecules.
  • Do wastewater treatment plants reduce anthropogenic stressors?
  • Wastewater treatment plants have been identified as an opportune barrier to reduce plastic-based anthropogenic stressors before they enter the aquatic environment 3, 4, 5. In particular, aggregation processes that occur through a physico-chemical treatment followed by settling can lead to high removal of nanoplastic.
  • Who performed the experiments with synthetic wastewater?
  • S.A.F., M.L. and R.S.K. performed the experiments with synthetic wastewater. S.A.F., Z.L. and B.B. sourced the municipal wastewater influents, activated sludge-treated samples and aerated lagoon water samples and performed the relevant experiments. M.L. designed and constructed the reactor for pilot-scale experiments.
