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.

Coagulation¨Cflocculation treatment of municipal wastewater based on anionized nanocelluloses - ScienceDirect

The anionic nanofibrillated dicarboxylated cellulose (DCC) bioflocculants synthesized here showed good performance in the coagulation¨Cflocculation treatment of municipal waste water. Their turbidity reduction efficiency fell short of that of the synthetic reference polymer, but their COD removal performance was as good as the latter.

Addressing water scarcity: cationic polyelectrolytes in water treatment and purification - Wilts - 2018 - Wiley Online Library

Depending on solvent and pH, the positively charged moiety and anionic counterions dissociate, thus enabling the polymer backbone to repel itself, adopting a ridged-rod conformation and allowing interactions with other negatively charged. Scheme 1 depicts the dissociation of counterions from a CPE backbone in the presence of water.

3.3.2. Characteristics of slime water. The main characteristics of slime water were as follows: high concentration, high content of fine particles, high ash content, many negative charges on the surface of particles. These particles kept stable dispersion in the water due to the repulsion of the homoelectric charge.

Synergistic coagulation effect of the cationic coagulant and anionic flocculant on fluorite tailings - ScienceDirect

In the flocculation stage, the polar groups of anionic flocculant rely on electrostatic attraction, the van der Waals force, and hydrogen bonds to adsorb tailings particles or small flocs. The flocculant simultaneously adsorbs tailings particles or small flocs by the adsorption bridging effect, gradually growing into large flocs, as shown in Fig. 6 .3.
