Main Difference – Ferric vs Non Ferric Alum. Alum is any chemical compound with the general empirical formula AB(SO 4) 2 ·12H 2 O where A is a monovalent cation and B is a trivalent metal ion. The most common monovalent cations are potassium and ammonium. The most common trivalent metal ions are aluminum and …
At any specific dosage, alum removed more DOC and UV 254, except at 30 mg/L under which the UV 254 removal by ferric chloride dramatically increased over the removal by alum. Zhou et al., found that ferric chloride effectively removed double bonds or aromatic ring unsaturated compounds [ 23 ].
This study seeks to derive a more rational approach to the use of coagulants in water treatment, particularly alum and ferric chloride, than is presently practiced. Amirtharajah and Mills2 produced a detailed design-andoperation diagram for alum coagulation. In this study, a similar operation diagram for Fe(II1) was developed by using data ...

Most studies reported that ligand exchange was the dominant mechanism of PO 4 adsorption with OH flocs regardless of whether the WTR was alum or iron based (Gao et al., 2013; Zohar et al., 2017).Additional reactions that are associated with the sorption capacity of WTR include hydroxide exchange, surface complexation, and co …
Ammonium Alum: Ammonium alum has the formula NH 4 Al(SO 4) 2 ·12H 2 O. Ammonium alum is used for many of the same purposes as potassium alum and soda alum. Ammonium alum finds applications in tanning, dyeing textiles, purifying water, and making textiles flame retardant. It's also used in the manufacture of porcelain cement, …

Background: Nitrate is an acute and well-known hazardous contaminant, and its contamination of water sources has been a growing concern worldwide in recent years. This study evaluated the feasibility of nitrate removal from water using the traditional coagulants alum and ferric chloride with lower concentrations than those used in the …
With aluminum sulfate, optimum coagulation efficiency and minimum floc solubility normally occur at pH 6.0 to 7.0. Iron coagulants can be used successfully over the much broader …
The optimum alum dosage was lower (1 g L −1) which was the lowest required dosage obtained the highest turbidity removal. The best performance of alum in removing turbidity from water was obtained at pH 7 following by pH 6. The coagulation efficiency of alum remained almost constant within the dosage range of 1–4 g L −1 at …

Liquid alum costs range from $.06 to $.20 per pound of liquid, while ferric chloride costs range from $.14 to $.21 per pound of liquid as of the spring of 2005. Alum is safer and easier to handle and less corrosive than ferric chloride. Generally, the O&M costs for chemical removal systems are greater than EBPR due to chemical addition costs.
