Flocculants for River-bed Sludge Dredging


Riverbed dredged sediment contains large amount of inorganic and organic colloidal particles, with high mass fraction and obvious interaction with each other, resulting in great resistance to sedimentation. The sediment dredging flocculants can destabilize, aggregate, flocculate, settle the sediment, fine particles and colloids via compressed double electric layer, electric neutralization, adsorption bridge, sediment roll sweep (net capture) and so on,  so as to realize the purpose of dehydration separation, river dredging, reduce pollution and improving the water quality.

˜Product Characteristics

The flocculants for river dredging has low cationic degree. It has the characteristics of fast reaction speed, short settling and consolidation time, low turbidity of water, low water content of sludge, no poison, non toxic and pollution and friendly environment.
