What is non ionic polyacrylamide flocculant used for?

Dissolving non-ionic polyacrylamide flocculant into a concentration of 0.3% and adding it to a crosslinking agent can play a role in sand control and consolidation when sprayed on the desert. Soil moisturizing agent It used as a soil moisturizing agent and the basic raw material for various modified polyacrylamide flocculants.

Can cationic polyacrylamide flocculants be used in river water?

The amount of flocculant added is 1/50 of that of inorganic flocculants, but the effect is several times higher than that of inorganic flocculants. For river water with severe organic pollution, it is better to use inorganic flocculants in conjunction with cationic polyacrylamide flocculants.

How does anionic polyacrylamide (Apam) work?

Anionic polyacrylamide (APAM) carries a negative charge, and its molecular chain contains polar groups such as carboxyl groups. These groups can neutralize charges with positively charged particles in water and form larger flocs through bridging, thus accelerating the sedimentation of particles in the suspension.

Why is anionic polyacrylamide important in water treatment?

These groups can neutralize charges with positively charged particles in water and form larger flocs through bridging, thus accelerating the sedimentation of particles in the suspension. Anionic polyacrylamide plays a significant role in water treatment in the following aspects:

What spectroscopy is used to identify anionic polyacrylamide flocculant?

The anionic polyacrylamide (APAM-T) flocculant was characterized by Fourier transform infrared spectroscopy (FTIR), 1 H nuclear magnetic resonance spectroscopy (1 H NMR), and scanning electron microscopy (SEM). Furthermore, the X-ray photoelectron spectroscopy (XPS) was conducted to measure the elemental composition.

What is anionic polyacrylamide used for?

Anionic polyacrylamide is suitable for treating positively charged particles such as suspended solids and colloids in wastewater. Compared to cationic PAM, anionic polyacrylamide is usually less expensive and is suitable for large-scale use.
