Research on Composite Flocculant Improving Substrate Sludge Dehydration

Abstract:

The dewatering effects of FeCl₃, AlCl₃ and PAM as flocculants for substrate sludge in Poyang Lake of SCAU were tested. The indexes, such as the filtrating volume, the moisture content, etc, were compared in order to achieve the best composite flocculant. The results showed that, when FeCl₃ was used with PAM in the ratio of 4:1, the highest filtrate volume 75mL was obtained. At the same time, when the dosing quantity is 3%, we obtained the best dewatering performances, such as the fastest velocity of filtrate, the highest degree of clarity with 88%, which were better than other flocculants.
