“…4 give demonstrations of up-climaxdown trend, suggesting that charge neutralization effect (Pal et al 2011) plays an important role in the flocculation process. In order to investigate the flocculation mechanism further, the ZPs of the final supernatants after reaching flocculation equilibrium as a function of dosage at various pH levels have been measured, as showed in Fig.…”

“…At pH 7, RC of Cu(II) decreased with the rise of dosage before reaching the minimum value at corresponding optimal dosages, then remarkably increased. This phenomenon indicated that charge attraction was possible to play an important role in the flocculation process [35,36], because excessive flocculant engendered restabilization effect due to the electrostatic repulsion. At pH 8, besides the lowest RC as aforementioned, the flocculation window also became much wider, which was believed to be a notable advantage for simplifying the operation difficulty in real water treatment works.…”

“…(Crini, 2006). Flocculation is a process that destabilized the finely divided particles, accelerate to make large flocs, so as to be settled and separated from the wastewater (Chang, Hao, & Duan, 2008;Pal, Ghorai, Dash, Ghosh, & Udayabhanu, 2011). Earlier, inorganic coagulants like alum, ferrous sulphate, poly AlCl 3 , ferric chloride have been used for wastewater treatment.…”
