The Usage of The Polyacrylamide in The Paper Making
The anionic polyacrylamide is mainly used as the flocculant. For The anionic polyacrylamide is mainly used as the flocculant. For the suspended particles, the coarse, the high concentration and the particles with the positive charges, and the waste water with the PH value as neutral or alkaline, the anionic polyacrylamide can accelerate the settlement of the particles suspending in the water

Polyacrylamide
Polyacrylamide (abbreviated as PAM) is a polymer with the formula (-CH2CHCONH2-). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for wa

- What is a Pam flocculating product?
- These flocculating products are used with active or passive BMPs. They’re exceptional on construction sites with slope or embankment washouts and where de-mucking sediment basins is required. With their negative charges, none of our PAM products change the water’s PH.
- What are new flocculants based on?
- Development of new flocculants based on carbon and non-carbon nanomaterials (e.g., dendrimers, zeolites, hyperbranched polymers, or graphite oxide) have also been discussed in works on desalination of sea water and treatment of surface and groundwater [ 225, 226, 227 ].
- Why are polymer flocculants used in water purification?
- Therefore, in modern water purification technologies, polymer flocculants are increasingly used. Polymer flocculants cause the formation of large, coherent aggregates (so-called flocs) that settle in the solution. Synthetic polymers are highly effective flocculants at low dosages but have poor shear stability.
- Are plant extracts a useful flocculant?
- Coagulation/flocculation studies were carried out on water samples taken from local drinking water sources. The results show that the plant extracts effectively remove water turbidity and are disinfecting, therefore may be a potential useful flocculants in near future.
