Ferric coagulants may be cheaper, it rather depends on what is available in the area. One advantage that they may have is that it is possible to have grades with different acid contents which may make getting the pH right easier. Also iron doesn't increase in solubility at higher pH as Al does. If you do get iron coming through it is often more visible. Ferric coagulants may be more corrosive though. To get a more pH tolerant coagulant though you may have to go to poly
aluminium chloride or similar.

Ferric Chloride is not cheaper but worse ferric chloride absorbs moisture how do you store that? Also, what about the ferric Bacteria but worse the smell? Water Treatment is dependent on quality and economy .
