Ferric Chloride – Fecl3
Ferric Chloride – Fecl3
Ferric chloride also called
Iron(III) chloride, is an industrial scale commodity chemical compound.
Chemical Formula : Fecl3
In water Treatment it is used coagulants or flocculants, for odor control to minimize hydrogen sulfide release, for phosphorus removal, and as a sludge thickening, conditioning and dewatering agent
In this application, FeCl3 in slightly basic water reacts with the hydroxide ion to form a flocculant of ferric hydroxide, or more precisely formulated as FeO(OH)−, that can remove suspended materials.
[Fe(H2O)6]3+ + 4 HO− → [Fe(H2O)2(HO)4]− + 4 H2O → [Fe(H2O)O(HO)2]− + 6 H2O
