Abstract:An study of treating heavy metal ions wastewater by lime - floeculation has been carried on. The results show that maintainning pH from 8.5 to 9.5, stir speed from 100 r/min to 120 r/min and keeping up the quantity of floceulafion from 9.0 mg/L to 10.5 mg/L can improve the rate of removal heavy mental ions.
Keywords:lime - flocculation   flocculation   heavy metal ions.
