A Critical Review on Flocculants and Flocculation

open access: yesNon-Metallic Material Science, 2019
The article critically reviews the applications of biopolymers in the area of water treatment. A number of biopolymers were reported for their flocculation behavior for treating the wastewater and making it suitable for various industrial as well as agricultural purposes via chemical alteration onto its backbone.

The flocculation mechanism and treatment of oily wastewater by flocculation [PDF]

open access: yesWater Science and Technology, 2017
Abstract In the present study, the performance of compound flocculants composed of different concentrations of polyaluminum chloride (PAC) and cationic polyacrylamide (CPAM), the influencing mechanism of the flocculation process and the effects of temperature, settling time, and speed and time of stirring were investigated.

Describing Mining Tailing Flocculation in Seawater by Population Balance Models: Effect of Mixing Intensity

open access: yesMetals, 2020
A population balance model (PBM) is used to describe flocculation of particle tailings in seawater at pH 8 for a range of mixing intensities. The size of the aggregates is represented by the mean chord length, determined by the focused beam reflectance ...

Applying a logistic growth equation to model flocculation of sediment in the presence of living and dead organic matter

open access: yesFrontiers in Marine Science, 2023
In the present study, we aim to parameterize a flocculation model, based on a logistic growth equation, by conducting laboratory experiments. The flocculation experiments are performed using two types of natural sediments and different flocculating ...

Modeling of Flocculation and Sedimentation Using Population Balance Equation

open access: yesJournal of Chemistry, 2019
Flocculation is a special phenomenon for fine sediment or silt in reservoirs and estuaries. Flocculation usually results in changes of size, morphology, and settling velocity of sediment particles and finally changes of bed topography of reservoirs and ...
