  • Is poly-aluminum chloride a good coagulant for wastewater treatment?
  • As a common and low-cost coagulant, poly-aluminum chloride (PAC) may be widely used for wastewater treatment. In this article, the impacts of PAC on activated sludge and the treatment efficiency of sequencing batch reactor were investigated over 100 d for domestic wastewater treatment.
  • Does poly-aluminum chloride affect sludge production?
  • The economic potential of poly-aluminum chloride (PAC) at full-scale sludge treatment plant and its impact on sludge production was explored in this study. The effect of recycling water on major… Effects of Al3+ on the microstructure and bioflocculation of anoxic sludge. International Journal of Environmental Science…
  • What is waste activated sludge (WWTP)?
  • As a byproduct of biological wastewater treatment, large amounts of waste activated sludge (WAS) are inevitably produced, which is becoming a big problem faced by wastewater treatment plants (WWTP) nowadays , . WAS is one typical type of solid wastes and easily causes secondary pollution if it is treated inappropriately.
  • Does polyaluminum chloride affect microfauna in activated sludge?
  • Hansen and Schuurman (1999) mentioned that polyaluminum chloride had a negative effect on the microfauna of activated sludge only at extremely high concentrations. However, the authors used other PAX coagulants, and they did not mention the species of observed ciliates and rotifers.
