摘要: Abstract The floc strength and regrowth properties of TiCl4, FeCl3, Al2(SO4)3 were comparatively evaluated using humic acid–kaolin synthetic water sample. At the given optimum dosage (20 mg/L as Ti, 8 mg/L Fe, 2 mg/L Al, respectively), growth, breakage investigated by use a laser diffraction particle sizing device. Jar tests conducted to investigate impact shear force period on re-aggregation potential. Results indicated that responses flocs increasing depend coagulant used. ability resist decreased with increase force. Floc also measured in response force, results suggesting order was TiCl4 > FeCl3 > Al2(SO4)3. these three coagulants after exposure high limited, formed TiCl4 displayed weakest recoverability. Similar obtained when different.
