Anionic polyacrylamide

Introduction:

Anionic polyacrylamide (HPAM) has the appearance of white powder particles, with a molecular weight ranging from 5 million to 25 million. It has good water solubility, can be dissolved in water in any proportion and is insoluble in organic solvents. The effective pH range is 7 to 14. It has the characteristics of a high polymer electrolyte in a neutral alkaline medium, is sensitive to salt electrolytes, and can be cross-linked with high-valent metal ions to form an insoluble gel.

Uses:

Industrial wastewater treatment has the best effect on suspended particles, high concentration, positively charged particles, neutral or alkaline pH value of water, steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing plant wastewater and other wastewater treatment.

Drinking water treatment:

Many water plants in my country source water from rivers, which have high sediment and mineral content and are relatively turbid. Although they have been precipitated and filtered, they still cannot meet the requirements. Flocculants need to be added, and the amount added is 1/50 of that of inorganic flocculants. But the effect is several times that of inorganic flocculants. For factories with serious organic pollution, it is better to use inorganic flocculants and our cationic polyacrylamide together.

Recovery of lost starch in starch plants and alcohol plants:

Many starch plants now have a lot of wastewater containing a lot of starch. Anionic polyacrylamide is now added to flocculate and precipitate starch particles. Then the precipitate is filtered through a filter press to become a cake, which can be used as feed. The alcohol in the alcohol plant can also be dehydrated with anionic polyacrylamide and recovered by filtering.
