Demonstrates improved turbidity reduction in kaolinite suspensions using cellulose as a flocculant, indicating safer environmental applications.

The aim is to evaluate the effectiveness of cellulose dissolved in sodium hydroxide as a flocculant for kaolinite suspensions.
Conducted experiments on kaolinite suspension treatment using cellulose and magnesium chloride.
Evaluated turbidity reduction after varying settling times (10 minutes and 20 hours).
Utilized response surface models to assess the impact of cellulose and magnesium chloride doses on turbidity.
Initial turbidity of 3200 NTU reduced to 4.7 NTU after 10 min with 20 ppm cellulose and 0.5 mM magnesium chloride.
Cellulose solution remains effective in saline water up to 0.5 M sodium chloride.
Demonstrated significant increase in particle size and settling rate of kaolinite.
