  • Are activated carbon-based processes a viable alternative to urban wastewater treatment?
  • Activated carbon-based processes and ozonation are so far the most viable advanced treatment options for enhanced removal of organic microcontaminants of emerging concern from urban wastewaters. This is evidenced by their increasing full-scale implementation in urban WWTPs in Europe, mainly in Switzerland and Germany.
  • What is a biological wastewater treatment plant (WWTP)?
  • The discharge of industrial water requires the removal of its pollutants, where biological wastewater treatment plants (WWTPs) are the most used systems. Biological WWTPs make use of activated sludge (AS), where bacteria are responsible for the removal of pollutants.
  • Can activated carbon adsorption be used with a good quality wastewater?
  • Experimental data modelled with the Freundlich isotherm. Since the activated carbon demand to achieve the desired removal of target microcontaminants highly depends on wastewater DOC content, adsorption is recommended to be used with a good quality wastewater (ideally DOC < 10 mgC/L) which will favor a good performance-dose balance [38, 47].
  • Are activated carbon-based processes and Ozonation a viable advanced treatment option?
  • 17.5. Final remarks and research needs Activated carbon-based processes and ozonation are so far the most viable advanced treatment options for enhanced removal of organic microcontaminants of emerging concern from urban wastewaters.
