    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).

    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.

    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

    Flocculants

    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 (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.
