  • 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.
  • Do poly aluminum chloride and poly ferric sulfate affect was digestion?
  • Poly aluminum chloride (PAC) and poly ferric sulfate (PFS) are widely used in wastewater treatment and sludge dewatering, resulting in their amounts being accumulated substantially in waste activated sludge (WAS). Till now, however, little information about their influence on WAS digestion is available.
  • Does iron-equivalent ferric sulfate inhibit PFS?
  • Compared to PFS, the iron-equivalent ferric sulfate showed less inhibition (11.1% versus 32.0%), and this gap might be ascribed to the “hydroxyl polymers” to some extent.
