文摘

Ti-based coagulants were compared with FeCl3 for algal turbid water treatment. TiCl4 and PTC achieved good flocculation over a broader pH range and coagulant dose. Turbidity removal efficiency was similar amongst the tested coagulants. PTC showed the fastest floc growth rate and also the largest floc sizes.
