cationic flocculant polyacrylamide
Cationic Polyacrylamide Flocculant/ Powder
The polyacrylamide is a synthetic cationic polymerization flocculants and so mainly related to chain length and the charge of the dewatering performance of polyacrylamide excessive dosage, the positive charge on the ion polyacrylamide adsorption, due to electrostatic repulsion, it will reduce the sludge settling performance, we should pay
Cationic Polyacrylamide-wastewater treatment chemical
Cationic polyacrylamide (CPAM for short) is a linear polymer composed of cationic monomer and acrylamide. Agent has functions of flocculation, decolorization, adsorption, turbidity removal, adhesion, etc. It can be used as a sludge dewatering agent and papermaking aid.

These cationic flocculants are also offered in a range of molecular weights. This enables the customer to select the optimum polymer depending on application needs, such as low molecular weights for low shear applications (e.g. gravity belt thickener) to very high molecular weights for high shear environments (e.g. centrifuge decanters).

Cationic polyacrylamide CPAM. Cationic polymeric flocculant is a kind of linear macromolecular compounds dissolve in water, the molecular weight between 600-12 million, cationic PAM in acidic or alkaline medium is electropositive, such can effectively suspended particles in the sewage wastewater with negatively charged for flocculation
Flocculants | Brenntag
Zetag ® Flocculant Technology. For many years cationic polyacrylamide flocculants have been used in the sludge dewatering process. Optimising the dewatered biosolids is essential to maintain the sustainability and efficiency of the process. Higher cake solids reduce the energy required for transporting and disposing at a landfill.
Synthesis, Characterization, and Flocculation Properties
The branched cationic polyacrylamide can be used as a novel flocculant in water and wastewater treatment. Acknowledgment This work received financial support from NWPU Basic Research Fund (JC20120249).
Synthesis of cationic polyacrylamide by low-pressure UV
Meanwhile, effective organic polymer flocculant, especially cationic polyacrylamide (CPAM), was developed and extensively used for turbidity separation because of their satisfactory solid-water separation performance . Generally, cationic polyacrylamide is copolymerized by acrylamide (AM) and cationic monomers in an aqueous solution.
The difference of anionic, cationic and Non-ionic
Polyacrylamide is not the only acrylamide unit, the acrylamide unit is mostly called polyacrylamide. Thus, polyacrylamide may contain structural units that can be ionized or hydrolyzed in water to carry charges. As a result, there are cationic, anionic, non-ionic, amphoteric ion type of various polyacrylamide anionic polyacrylamide
In wastewater treatment, polyacrylamide-based flocculants are commonly used. Because they can contain potentially toxic acrylamide residues, flocculants based on natural biopolymers are preferred over synthetic polymers. An effective biopolymer flocculant for harvesting microalgae is chitosan, which is prepared by deacetylation of chitin
Polyacrylamide - Wikipedia
Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N '-methylenebisacrylamide.In the cross-linked form, the possibility of the monomer being present is reduced even further.
