  • How to use ferric sulfate as a coagulant?
  • Here, using a magnetic mixer stirrer, 500ml of raw water was mixed with a certain dosage of ferric sulfate in that used as the coagulant at a certain pH in a beaker glass through a high-speed mixing (240 rpm) for five minutes and low-speed mixing (60 ppm) for 10 minutes, respectively. Subsequently, the absorption was measured using UV/Visible.
  • Can polymeric iron sulphate be used for industrial effluent treatment?
  • The combination of PFS with other chemicals or natural coagulants has high potential in treating water or wastewater. This is due to their greater effectiveness and cheaper cost compared to inorganic coagulants and organic flocculants . Previous studies of composite polymeric iron sulphate for different industrial effluent treatments
  • Is ferrous sulfate a coagulant?
  • Ferrous sulfate is often used in as a coagulant in wastewater applications as it is cheaper than ferric chloride. However, as was shown in Eq. (4), once dosed it undergoes a two-step reaction to form the iron hydroxide needed to react with inorganic constituents.
  • Can aluminum sulfate and ferric chloride improve the flux of MF treatment?
  • Although aluminum sulfate and ferric chloride could improve the flux of the ensuing MF treatment, the optimal coagulant dosages to achieve effective pretreatment were different: 2–30 mg/L for aluminum sulfate and >15 mg/L for ferric chloride.
