Al-based and Fe-based salts are widely used inorganic coagulant in water treatment.
However, the residual Al in finished water has accumulation harm to human body and animal tissue [3].
In addition, it has been widely recognized that removal of OMs by Fe-based coagulant was superior to that by Al-based salts [4].
