a review on application of flocculants in wastewater treatment

A review on application of flocculants in wastewater treatment

Flocculation is an essential phenomenon in industrial wastewater treatment. Inorganic coagulants (salts of multivalent metals) are being commonly used due to its low cost and ease of use. However, their application is constrained with low flocculating efficiency and the presence of residue metal concentration in the treated water.

Combined use of inorganic coagulants and cationic polyacrylamide for enhancing dewaterability of sewage sludge

Generally, adding coagulant destabilizes colloidal flocs by charge neutralization and bridge-aggregation ability is obtained with the flocculant dose (Zeng et al., 2007). As a result, use of coagulant and flocculant increased the particle size of the sludge flocs

polymer flocculants

Polymer Flocculants

Polymer flocculants are water-soluble polymers which can form flocs from individual small particles in a suspension by adsorbing on particles and causing destabilization through bridging or charge neutralization. Polymer flocculants are high molecular weight polymers and have hydrogen-bonding groups and/or ionic groups in the molecule.

Optimization of coagulant dosage and pH to reduce the turbidity and chemical oxygen demand (COD) of synthetic dairy wastewater (SDW) was investigated using a full factorial design (FFD) and full factorial design with center point (FFDCP). Two organic coagulants, polyacrylamide (PAM) and Tanfloc were used. The optimal values of coagulant dosage and pH were determined using a multiple response ...
