Does cationic polyacrylamide flocculate Phaeodactylum tricornutum?

However, Nguyen et al., observed high flocculation efficiency of marine microalgae Phaeodactylum tricornutum with a cationic polyacrylamide flocculant (FO3801). The discrepancy in the literature suggested that a future flocculation study using one type of polymer with multiple marine species. 4. Conclusions

Which cationic polymer has the best flocculation efficiency?

The PAmPTAC polymer had an optimal dose at 252 mg/g dry biomass. The difference in flocculation efficiency between two polymers is likely due to the differences in molecular weight. In the flocculation process by cationic polymers, charge neutralization of microalgal cells initiates floc formation.

Does polyacrylam IDE and cationic (k-1384) remove oil?

The DAF system was operated as a batch study using DAF jar-test wi th a pressure of 4–5 atm. a nd recycle ratio o f 30%. Results indicated that the use of polyacrylam ide and cationic (K- 1384) did not offer a good solu tion. adhesion and the overall DAF performance. The best removal rate for oil removal was obtained

Can cationic polymer flocculants be developed using photo-polymerization technique?

In this study, we utilized recent developments in the photo-polymerization technique to develop two cationic polymer flocculants by polymerizing two types of monomers for harvesting Chlorella vulgaris (C. vulgaris) and Porphyridium purpureum (P. purpureum), which are freshwater and marine microalgae species, respectively.

Can polyacrylam IDE be used in DAF jar test?

coagulated solids and emulsion droplets (otation collector). The DAF system was operated as a batch study using DAF jar-test wi th a pressure of 4–5 atm. a nd recycle ratio o f 30%. Results indicated that the use of polyacrylam ide and cationic (K- 1384) did not offer a good solu tion. adhesion and the overall DAF performance.

Which cationic polymers are used to harvest freshwater microalgae?

Two positively charged cationic polymers including poly [2 (acryloyloxy)ethyl]trimethylammonium chloride (PAETAC) and poly (3 acrylamidopropyl)trimethylammonium chloride (PAmPTAC) were synthesized using the UV-induced radical polymerization, for harvesting both freshwater and marine microalgae.
