Dehydration Properties of Different Flocculants in the Processes of Sludge Dewatering

摘要

Sludge dewatering is a crucial factor in the reduction of sludge volume and transportation costs. Different flocculants were applied in the sludge dewatering experiments and their dehydration effects were discussed. Several parameters of the sludge flocculation were presented, such as water content, turbidity, transmittance and ζ potential. The results showed that the composite flocculation could promote respective flocculation performance and AEO/PAM/PFAC had good dehydration ability.
