Calcium hydroxide is used as a flocculant for treating both industrial and wastewater treatment plants.
The flocculation is a solid-liquid separation process, which consists of adding a flocculant into the raw water, after which finely divided or dispersed particles are aggregated or agglomerated together to form large particles of such a size (flocs) which settle and cause clarification of the system [4].
PAM is a commonly used flocculant in wastewater treatment facilities.
In addition to flocculant dosage, the effects of pH on turbidity and zeta potential were explored at the optimal dosage of 2.0 mg [l.sup.-1].
The dirty process water is pumped into the clarifier as flocculant is added via an automated system.
