  • Can activated sludge remove heavy metals from wastewater?
  • The long-term treatment of Pb 2+ -, Cu 2+ -, and Ni 2+ -containing wastewater by activated sludge a SBR activated sludge system was continuously carried out for 123 days, and the mechanism of heavy metal removal by activated sludge was discussed through static adsorption experiments and sludge characteristics.
  • Can waste-water treatment technologies remove heavy metals?
  • In this article, current development in recent waste-water treatment technologies to remove heavy metals has been reviewed and summarized.
  • What methods are used to remove heavy metals from wastewater?
  • Conventional wastewater treatment methods for heavy metal removal include physicochemical and biological methods (Fu and Wang 2011; Jacob et al. 2018 ).
  • Are heavy metals toxic to activated sludge?
  • However, the SBR activated sludge system was significantly affected by heavy metals, showing that heavy metal showed biological toxicities to activated sludge.
