Polyaluminum Ferric Chloride (PAFC)
Polyaluminum ferric chloride (PAFC) is a composite inorganic coagulant combining the charge neutralization of aluminum with the strong flocculation of iron species. It offers enhanced turbidity and color removal compared to single-metal coagulants, particularly effective for treating high-color surface waters and oily wastewater.
