A review on chemical coagulation/flocculation technologies for removal of colour from textile wastewaters.
TL;DR: Some novel pre-hydrolysed coagulants such as Polyaluminium chloride (PACl), Polyal aluminium ferric chloride (PAFCl), Polyferrous sulphate (PFS) and Polyferic chloride (PFCl) have been found to be more effective and suggested for decolourisation of the textile wastewater.

Natural organic matter removal by coagulation during drinking water treatment: A review
TL;DR: Most of the NOM can be removed by coagulation, although, the hydrophobic fraction and high molar mass compounds of NOM are removed more efficiently than hydrophilic fraction and the low molarmass compounds.

Recent Advancement of Coagulation–Flocculation and Its Application in Wastewater Treatment
TL;DR: In this article, a critical review on recent studies of coagulation-flocculation treatment processes of various industrial wastewaters is presented, where the limitations and challenges for the coagulated-fluctuation process such as toxicity and health hazard posed by inorganic coagulants, production of large amount of toxic sludge, ineffectiveness in removing heavy metals and emerging contaminants, increase in effluent color, inefficient pollutant removal using natural coagULants, and complexity of scaling up procedure are presented.

Flocculation properties of some water-soluble cationic copolymers toward silica suspensions: A semiquantitative interpretation of the role of molecular weight and cationicity through a “patchwork” model
TL;DR: In this paper, the authors examined the sedimentation rate, the clarification and the height of the sedimented bed in connection with some operative conditions (stirring), some physicochemical measurements (adsorption isotherms, electrokinetic potential), and the characteristics of the flocculant (M w, cationicity).
Humic macromolecules in natural waters
TL;DR: One of the more important characteristics of humic substances is their ability to form water-soluble and water-insoluble complexes with metal ions and hydrous oxides and to interact with clay minerals and various organic compounds such as alkanes, fatty acids, and toxic organic substances such as pesticides.
Super-stoichiometric charge neutralization in particle-polyelectrolyte systems.
TL;DR: The adsorption of poly(vinylamine) (PVA) on poly(styrene sulfate) latex particles is studied, and its consequences on the charging behavior and suspension stability are investigated.
Manipulation of micrometer-scale adhesion by tuning nanometer-scale surface features.
Natalia Kozlova,Maria M. Santore +1 more
TL;DR: It is demonstrated how the adhesion rates of micrometer-scale particles on a planar surface can be manipulated by nanometer-scale features on the latter, and at the threshold, the length scales of the patch spacing and of the interactive surface area between the particle and the surface become similar.
