A novel polyamidine-grafted carboxymethylcellulose
AbstractThis study facilitates the synthesis process of a novel graft copolymer (flocculant) using carboxymethyl cellulose, acrylonitrile and N-vinyl formamide as raw materials. The carboxymethyl cellulose graft polyamidine (CMC-g-PAMD) can be used as new flocculant to replace the traditional polyacrylamide flocculant, which manifested its excellent flocculation and degradation efficiency.

It means that a high molecular weight polymer material can be grafted onto an active site, such as polyacrylamide (PAM), to enhance its flocculation performance [14,15]. It is well known that the sludge colloid has a negative charge. The cationic polyacrylamide (CPAM) flocculant is positively charged and is suitable for charge neutralization.
However, a dual starch-polyacrylamide polymer system used during ballasted flocculation was able to significantly reduce the required polyacrylamide dosage (around 70% for surface water) without

Non-ionic PAM: It is the most appropriate to use NPAM, when the sewage is acidic. It is also used as agents for the textile pulp, paper chemicals, water shutoff agent, and etc.Because of its non-ionic functional group, PH value and salts have a little influence on NPAM’s flocculation.
