WebFerric chloride (FeCl3) is the most common iron salt used to achieve coagulation. Its reactions in the coagulation process are similar to those of alum, but its relative solubility and pH range differ significantly from those of alum. Both alum and ferric chloride can be used to generate inorganic polymeric coagulants. WebIt is noncombustible. When wet it is corrosive to aluminum and most metals. Pick up and remove spilled solid before adding water. It is used to treat sewage, industrial waste, to …
WebOptimized GVL/water/FeCl 3 pretreatment (70% GVL/300 mM FeCl 3 in 30% water at 120 °C for 3 h) resulted in high delignification (74%) and hemicellulose dissolution (85.6%).

WebFeCl3 was found to be superior to other coagulants tested. At pH 4 and 12, fair removal of suspended solids was observed at a reasonably low coagulant dose, i.e., 600 mg L (-1); hHowever, about 2500 mg L (-1) of coagulant was required to achieve good removals at pH 6. Better removals were achieved at higher temperature. In the largest application iron(III) chloride is used in sewage treatment and drinking water production as a coagulant and flocculant. In this application, an aqueous solution of FeCl3 is treated with base to form a floc of iron(III) hydroxide (Fe(OH)3), also formulated as FeO(OH) (ferrihydrite). This floc facilitates the separation of suspended materials, clarifying the water. Iron(III) chloride is also used to remove soluble phosphate from wastewater. Iron(III) phosphate is i…
