چکیده انگلیسی


• The proper amount of PAM was 1 mg/L when combined with PTS.
• PTS-PAM attained better NOM removal and PAM-PTS attained better turbidity removal.
• Floc size, strength and recovery ability was significantly enhanced by the PTS-PAM.
• PTS-PAM floc had a looser structure than that of PTS, while PAM-PTS floc had a more compact structure.
• Photocatalytic activity of sludge reused TiO2 was enhanced by the addition of PAM.

This study focused on the application of polyacrylamide (PAM) as a coagulant aid of polytitanium sulfate (PTS) in humic acid-kaolin water treatment. Coagulation performance and floc properties were all measured in terms of dose amount and dose sequence of PAM and PTS which is meaningful for the practical application. Results showed that PTS-PAM (PTS dosed firstly) attained better natural organic matter (NOM) removal and PAM-PTS (PAM dosed firstly) attained better turbidity removal. Floc size was significantly enhanced by the PTS-PAM, while floc size of PAM-PTS attained similar size as that of PTS alone. Floc strength and recovery ability were also significantly improved by PTS-PAM. Moreover, PTS-PAM floc had a looser structure than that of PTS, while PAM-PTS floc and PTS floc had similar and more compact structure. The effect of PAM on the sludge reuse process was also studied. Results showed that the addition of PAM had a positive effect on the photocatalytic activity of sludge prepared TiO2.
