Abstract�� This study was about to remove humic acid from seawater by enhanced coagulation with micro-size materials SiO_2,FeCl_3 and PAC.The results showed that the removal rates of turbidity and humic acid by mixed FeCl_3 and PAC were more efficient than they were used respectively.With the optimum ratio m(Fe)/m(Al_2O_3)=2 and micro-size materials,the removal rates of turbidity and humic acid were increased to 94% and 95%,respectively.The sedimentation time was shortened and the floccule could be separated from the water more completely.The mixed flocculant is applicable in a wide range of water temperature and pH value.
