  • How much PAC do you need for wastewater treatment?
  • Operational experience has shown that for wastewaters with DOC below 10 mgC/L a 10–20 mg/L PAC dose is usually necessary for PAC set-ups downstream the biological treatment (1–2.5 mgPAC/mg DOC), while one needs 15–30 mg/L for PAC dosing directly into the biological treatment reactor (2–3 mgPAC/mg DOC) [35, 42, 44].
  • What is powdered activated carbon (PAC) adsorption?
  • One of them is adsorption [1–7]. To improve the removal of organic compounds, the addition of powdered activated carbon (PAC) in advanced conventional water treatment processes is commonly used in full-scale water treatment plants.
  • Can PAC be used in the field of wastewater treatment?
  • To fill this gap, we reviewed 27 pilot-, large- and full-scale PAC applications in the field of wastewater treatment with a specific focus on the implemented PAC separation processes. The operating conditions and removal efficiencies of all set-ups were collated and summarized.
  • What is the Doc normalized PAC dose for WWTP effluent?
  • However, as only three identical PAC doses have been tested in the different steps, different ranges of DOC normalized PAC doses are covered. Due to the high DOC concentration in the WWTP influent, the maximum tested specific dose was 1.2 mg/mg (100 mg/L PAC) while the lowest specific PAC dose for the WWTP effluent was 1.8 mg/mg (20 mg/L PAC).
