  • What is poly aluminum-ferric chloride (PAFC)?
  • Author to whom correspondence should be addressed. Poly aluminum-ferric Chloride (PAFC) is a new type of high efficiency coagulant. In this study, high iron type gangue is used as a main raw material. It is calcined at 675 °C for 1 h and 3% CaF 2 is added to the calcined powder and reacted with 20% hydrochloric acid at 93 °C for 4 h.
  • Is polyaluminum ferric chloride an inorganic coagulant?
  • 1. Introduction Polyaluminum ferric chloride (PAFC) is an efficient inorganic polymeric coagulant [1], [2]. Many studies [3], [4], [5] have demonstrated that inorganic polymeric coagulants were more effective than conventional inorganic coagulating salts in coagulation due to their resistances to the influence of wastewater initial pH.
  • Is ferric chloride a better coagulant than alum?
  • Ferric chloride is a more efficient coagulant than alum at different ranges of turbid water. In this study, the effects of employing a natural coagulant such as “Walnut coat” with PACl and synthetic polyacrylamide with PACl for removing turbidity are compared to using PACl alone.
  • 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.
