Effects of different coagulants in treatment of TiO2-humic acid (HA) water and the aggregate characterization in different coagulation conditions

- Coagulation behaviors by PACl and nano-Al13 displayed less variation.
- Nano-Al13 produced larger flocs under smaller dosage.
- Fractal dimension formed by nano-Al13 and PACl was larger.
- Strength factor increased with increasing the coagulant dosage using AS.
