1、 Application field
River dredging sediment contains a large number of inorganic and organic colloidal particles with high mass fraction and obvious interaction, resulting in large settlement resistance. The river dredging flocculant will destabilize, aggregate, flocculate and precipitate the sediment, fine particles and colloids through the functions of compressing double electric layer, electric neutralization, adsorption bridging, sediment sweeping (net capture), so as to realize dehydration and separation, so as to achieve the purpose of river dredging, reducing pollution and improving water quality.
2、 Product characteristics
River dredging flocculant is a low cationic product, which has the characteristics of fast reaction speed, short settlement and consolidation time, low water turbidity, low silt moisture content, non-toxic, pollution-free and environment-friendly.
