Grafted flocculants
WebThe performance test of grafted flocculants was done by clarifying the artificial wastewater kaolin suspension (10 g of kaolin in 1000 mL of aquadest). The grafted flocculant (10 mg) was dissolved into 20 ml aquadest. Then, a certain dosage of flocculant solution (4 ml) was poured into 500 ml of kaolin suspension. WebJul 5, 2024 · But, natural flocculants are needed in large dosage due to its moderate flocculating efficiency and shorter shelf life. Thus, in order to combine the best properties of both, synthetic polymers are grafted onto the backbone of natural polymers to obtain tailor-made grafted flocculants.

WebThe flocculation performance of these two flocculants, including flocculants dosage, settling time and floc size, was carefully studied and compared. Results suggested that poly (N,N-dimethylacrylamide) grafted cellulose nanocrstyals showed better flocculation performance than polyacrylamide grafted ones. WebWe hypothesize that, if grafted poly(acrylic acid) chains can form IPC complexes with these flocculants (PDAEC and PDADMAC), it should absorb onto the PCG surface and result in a net change to the observed swelling of the film when removed from the supernatant.
