Flocculation is a water and wastewater treatment technology whereby the large aggregation
of flocs in water can be formed and be later separated through sedimentation. This review …

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 …

Biopolymer-based flocculants have become a potential substitute for inorganic coagulants
and synthetic organic flocculants due to their wide natural reserves, environmental …

In recent years, the use of chitosan and its derivatives as flocculants in water treatment has
received considerable attention due to their many advantages, including their widespread …

Graft modified flocculants have recently received increasing attention in the field of water
treatment as they have the combinative advantages of synthetic and natural polymeric …

Polymer flocculants are used to promote solid–liquid separation processes in potable water
and wastewater treatment. Recently, bio-based flocculants have received a lot of attention …

Contaminants in real water are normally complicated. Surface charges of suspended
colloidal particles can be either negative or positive. In this work, a series of amphoteric …

In recent years, close attention has been paid to microbial flocculants because of their
advantages, including safety to humans, environmental friendliness, and acceptable …

Plant-based coagulants/flocculants are foreseen to be a major progress in water treatment
technology owing to their safety, biodegradability and availability, unlike synthetic chemical …

To achieve economical and efficient decolorization, two novel flocculants, weakly
hydrophobic comb-like chitosan-graft-poly (N, N-Dimethylacrylamide)(CSPD) and strongly …
