  • Which coagulant, Fe(Cl)3, alum, or PACl is better at removing arsenic?
  • Is arsenic removal limited by the mass transfer of arsenic to a precipitated coagulant surface, or by capture of the precipitated coagulant by plate settlers and filters?
  • Would a floc blanket formed from coagulant precipitate enhance arsenic removal?
  • Does addition of a small amount of clay enhance flocculation and arsenic removal?
  • How can we reduce the amount of coagulant loss to the reactor walls? (contact chamber, clay)
  • What is arsenic removal correlated with? What is the limiting factor?
  • Due to the geometry of arsenic flocs, should we consider a coagulation-filtration system rather than attempting flocculation and sedimentation?
