  • What is poly ferric sulfate (PFS)?
  • Poly ferric sulfate (PFS) with the general formula of [Fe2 (OH) n (SO4)3-n/2] m (n < 2, m > 10) is a relatively new kind of inorganic coagulant. It has been reported by several researchers that it e...
  • Does poly ferric sulfate affect methane production?
  • Poly ferric sulfate (PFS), one of the typical inorganic flocculants widely used in wastewater management and waste activated sludge (WAS) dewatering, could be accumulated in WAS and inevitably entered in anaerobic digestion system at high levels. However, knowledge about its impact on methane production is virtually absent.
  • What is the chemical formula for PFS?
  • Generally, PFS is dark brownish red in colour [23, 31], more viscous than other commercially available inorganic coagulants, less corrosive [31, 41, 54], and leaves less iron residue over a wide pH range [41, 55]. PFS has the chemical formula [Fe 2 (OH) n (SO 4) 3−n/2] m , where n < 2 and m > 10 [38, 47].
