  • Does disperse dye water treatment improve coagulation efficiency?
  • Furthermore, the floc formed in reactive yellow wastewater treatment was larger and looser than that formed in disperse blue wastewater, with poorer strength and recovery ability, which can also interpret the better coagulation efficiency in disperse dye water treatment.
  • Is PFS a good coagulant?
  • Furthermore, it has been reported by several researchers that PFS exhibits a superior efficiency in the removal of chemical oxygen demand (COD), biochemical oxygen demand (BOD), turbidity and colour, than the conventional coagulants based on iron , , .
  • Is PFS safe for drinking water?
  • Also, it can be used in a wide range of pH and temperature, due to its strong hydrolysis. Meanwhile, some preliminary toxicity studies suggested that drinking water treated with PFS is safe for human consumption .
  • Is PFS a polymeric salt?
  • In polymeric form, PFS is one of the pre-hydrolysing metallic salts with the chemical formula [Fe2 (OH) n (SO4)3−n/2] m (where, n < 2, m > 10) and has a dark brownish red colour as well as is more viscous and less corrosive. PFS has an amorphous structure with small traces of crystallinity, containing both hydroxyl and sulphate functional groups.
