View the article online for updates and enhancements. Abstract. Polymeric aluminum ferric sulfate (PAFS) was a novel inorganic composite coagulant, prepared by direct oxidation process using aluminum oxide (Al2O3) and ferrous sulfate heptahydrate (FeSO4·7H2O) as typical materials.
Is polymeric aluminum ferric sulfate a good coagulant?
Furthermore, Polymeric aluminum ferric sulfate (PAFS) as a novel inorganic composite coagulant can obviously speed up the sedimentation rate, decrease costs, color and toxins, which was superior to PAC, PFS and PFSS.
Which coagulant is prepared by polymeric aluminum ferric sulfate (PAFs)?
Therefore, many Al–Fe composite coagulants have been prepared such as Polymeric Aluminum Ferric Sulfate (PAFS), Polymeric Aluminum Ferric Chloride (PAFC) etc. Polymeric Ferric Sulfate (PFS) is a pre-hydrolyzed coagulant, prepared by partially neutralization of ferric sulfate.
What is poly ferric sulfate?
Poly ferric sulfate is a kind of superior performance of inorganic polymer flocculant, is light yellow amorphous solid,easily soluble in water. Widely used in drinking water, industrial water, all kinds of industrial wastewater and urban sewage purification treatment, sludge dewatering, etc.
What is polymeric ferric sulfate?
Polymeric ferric sulfate is widely used in drinking water, industrial water, all kinds of industrial wastewater and urban sewage and sludge dewatering purification treatment. Polyacrylamide (PAM) is a linear polymer, chemical formula is (C3H5NO) N.
Why is sulfuric acid used in oxidation of ferrous sulfate?
That mainly because oxidation reaction of ferrous sulfate was conducted in acid condition, a certain dosage of sulfuric acid is advantageous to the reaction, which could improve the ability of flocculation. The optimum SO42-/Fe molar ratio was 0.35, and the turbidity and HA removal efficiency reached 95.6%, 90.4%, respectively. Figure 2.
