  • How PAC is used in water and wastewater treatment plants?
  • The preferred capability of PAC in water and wastewater treatment plants is the removal of colloids and suspended particles, metal ions, phosphates, organic materials, hazardous metals, and even color . Currently, PAC is available on the market as either liquid or powder product .
  • Does PAC leak into wastewater treatment plant effluent?
  • Particle measurement yields a high amount of data on effluent particles. However, PAC was found to be in the same size range as many typical microbiological wastewater constituents, and analyses are thus non-selective. In order to assess PAC leakage into the wastewater treatment plant effluent, PAC-selective analytical methods have been developed.
  • Does PAC addition enhance phosphorus removal in wastewater treatment?
  • The average inhibition rate of DHA and OUR was 32.1 and 55.3%, respectively. PAC addition gave proof to the increase of MLSS by some 40%. Results obtained from the present work confirmed that PAC addition, despite the toxicity and inhibition on micro-organisms, favored phosphorus removal in wastewater treatment.
  • Are there practical recommendations for Pac separation processes in wastewater treatment?
  • A range of different PAC separation processes is available today, but a systematic method comparison and derivation of practical recommendations is still missing. 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.
