    2021-2-1 · 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.

  • Novel insight into sludge dewaterability mechanism

    2020-3-1 · Today, polymeric aluminium ferric chloride (PAFC) has emerged as a low cost and efficient inorganic polymeric coagulant . This reagent coagulates particles better than PAC and PFS , potentially effectively improving sludge dewaterability, due to its stronger charge neutralization effect. However, coagulants are limited in their ability to deeply dewater sludge, because coagulants do not effectively …
