Research on the removal of algae by inorganic-organic compound modified bentonite

Abstract-By the new environment-friendly surfactant (C₁₂ Alkyl glucoside quaternary ammonium) and inorganic modifier (aluminum chloride) modified bentonite, study on the removal of algae with the dosage of organic and inorganic modifier, the concentration of modified bentonite and pH value. The result shows the modified bentonite provides a good condition in the removal of algae after the modified bentonite has been greatly improved in the structure and performance. Under the AlCl₃ · 6H₂O dosage of 4mmol/g, organic modifier dosage of 8mmol/g, modified bentonite concentration of 250mg/L and pH value of 6 to7, the effect on removal of algae will reach best.
