  • 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.
  • Does PAFC coagulate municipal wastewater?
  • Since PAFC is synthesized based on poly ferric and poly aluminum, PAFC has the advantages of a vigoroso bridging ability and a broad coagulation pH range . However, few studies reported that PAFC flocculated municipal wastewater as an A-stage to capture carbon.
  • What is PAFC from coal gangue?
  • The XRD and FT-IR spectra showed that the prepared product is a mixture of PAFC with different degrees of polymerization. The preparation of PAFC from coal gangue can realize the resource utilization of gangue. It is mainly used for the treatment of coal industrial wastewater and the treated water can be recycled.
  • Do surface characteristics of PAFC and flocs affect coagulation mechanisms?
  • However, there was lack of systematic research on the surface characteristics of PAFC and the flocs generated in water treating process and their effect on the coagulation mechanisms.
