Iron(III) sulfate (or ferric sulfate), is a family of inorganic compounds with the formula Fe 2 (SO 4) 3 (H 2 O) n.A variety of hydrates are known, in fact are the most commonly encountered form of "ferric sulfate". Solutions are used in dyeing as a mordant, and as a coagulant for industrial wastes.It is also used in pickling baths for aluminum and steel.
Get PriceA novel inorganic polymer flocculant, poly-ferric sulfate (BPFS) was prepared by oxidation of ferrous sulfate using domestic Thiobacillus ferrooxidans (T·f) under acid condition.The optimal conditions for the preparation were pH value of 1.5, (NH 4) 2 SO 4 dosage of 0.5 g/L, initial Fe 2+ concentration of 45g/L, inoculum 10%, rotating speed of 120 r/min, …
Get PriceSodium-jarosite is a type of industrial waste that results from hydrometallurgy and inorganic chemical production. The iron content of jarosite residue may be utilized to produce theoretically the ferrous materials. The difficulty in production of high quality poly-ferric sulfate (PFS) is how to remove impurities contained in jarosite residue. This paper proposes …
Get PriceThe aim of this work was to produce a ferric sulphate rich solution from acidic coal mine drainage that could be used as coagulant. Precipitating the iron at pH 3.8, followed by dissolution in sulphuric acid, produced a coagulant consisting of 12.4% iron and 1.3% aluminium. Water treatment tests proved that this coagulant was as efficient as the coagulant chemicals …
Get PricePoly 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.
Get Price10%The difficulty in production of high quality poly-ferric sulfate (PFS) is how to remove impurities contained in jarosite residue. This paper proposes a novel method for disposing sodium-jarosite which can be used to synthesize PFS, a very important reagent for treating waste water.
Get PricePoly 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 availa …
Get PriceAmong Al-based and Fe-based flocculants, prepolymerized coagulants such as poly aluminum chloride (PAC) and poly ferric sulfate (PFS) have been used worldwide in recent decades (Bratby, 2016). PAC is made from partial hydrolysis of AlCl 3 solution in a specific reactor, generally consists of Al monomers, dimer, trimer, Al 13, and inert large ...

Get Price10%In the work conducted by Rao et al. ( 1992) on an AMD from a Canadian polymetallic mine, ferric sulphate (FS) was produced by the reaction of ferric hydroxide recovered from the AMD with sulphuric acid. To avoid the co-precipitation of undesirable metals, amine was used to reduce the co-precipitation at pH 3.5–3.6.
