this study evaluates the effectiveness of adsorption process by granular activated carbon (gac) compared with a novel formulation of coagulation - flocculation process for dye removal from textile wastewater. in this regard, acidic, reactive, disperse and direct red dye are used to prepare the synthetic dye. dominant wave length for each dye is determined by spectrophotometeric method. using ga...

Acacia gum (AG) was grafted with polyacrylamides different catonic ratios obtained by using amounts of acrylamide (AM) and methacrylatoethyl trimethyl ammonium chloride (DMC (cationic monomer)). The thermal properties these products were investigated differential scanning calorimetry (DSC) thermogravimetric (TGA) analyses. formation confirmed FTIR spectroscopy analysis. effects cationic polyacr...

We report the use of near-infrared (NIR) radiation to trigger the irreversible flocculation of poly(oligo(ethylene glycol) methacrylate)-stabilised polypyrrole nanoparticles in physiological buffer.

Introduction: The most important environmental problem of automotive industries is the produced wastewater due to its various processes. The flocculation and coagulation along with chemical sequestration are among important processes for removing contaminants from wastewaters. The aim of this study is to investigate the efficiency of coagulation and flocculation process along with chemical sequ...

The model based on logistic growth theory, that was introduced in Chassagne, Claire, and Zeinab Safar. “Modelling flocculation: Towards an integration large-scale sediment transport models.” Marine Geology 430 (2020): 106361, can be used to the time evolution of either particle (floc) size or concentration particles a given size. In present article, we show how this easily linked many studies p...
