Fly-Ash Vs. Industrial Alum: A Comparative Study of Flocculation CharacteristicsAuthor(s): Dinesh Prakash Upadhyay
A comparative study of flocculation characteristics of industrial alum and the fly-ash based alum has been performed. The fly-ash based alum can replace the industrial alum. However higher concentration would be required than the industrial alum. Moreover, since the fly-ash alum is more acidic, therefore, more lime dozing is also required to compensate pH decrease.
