The sediment from river dredging is particles containing a large amount of inorganic and organic colloids, with high mass fraction and obvious interaction, resulting in large settlement resistance. The river channel desilting flocculant will make the sediment, fine particles and colloid in it destabilize, aggregate, flocculate and precipitate, realize dehydration and separation, and achieve the goal of river dredging, reducing pollution and improving water quality by compressing the double electric layer, electric neutralization, adsorption and bridging, and sediment sweeping (net capture).
The river dredging flocculant is a low cationic degree product with the characteristics of fast reaction speed, short settling and consolidation time, low water turbidity, low water content of sludge, non-toxic and pollution-free, and environmentally friendly.

① First add lime or alkali to adjust the pH value to 7-9
② After adding inorganic flocculant polyaluminum chloride, the sludge will produce small flocs
③ Finally, polyacrylamide is added to separate the muddy water from the river sludge quickly
① Generally, 0.1%~0.3% water solution can be prepared during use, and it is appropriate to use neutral water without salt impurities;
② Put the product into the mixed water evenly, and control the mixing speed at 100-300rpm to make it fully dissolved (do not add dry powder before adding water);
③ The solution of this series of products should be prepared and used immediately. After preparation, it should not be placed for more than 24h. When preparing, transferring and storing this product, equipment made of stainless steel, plastic, glass or fiberglass should be selected;
5.Packaging, transportation and storage
25kg per bag, It can also be customized according to user needs, The shelf life is 2 years. The product is easy to absorb moisture and should be stored in a cool, ventilated and dry warehouse.
