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

What is dewatered polyacrylamide emulsion?

.Dewatered emulsionsDewatered polyacrylamide emulsions differs from standard by the fact that they contain less than 6% water, with the result that the hydrogel has become almost the dry polymer itself. The consistency of the polymer is simi ar to plastic material. Most dewatered polyacrylamide emulsions from SNF ha

Is polyacrylamide emulsion a liquid or a solid?

the dry polymer itself. The consistency of the polymer is simi ar to plastic material. Most dewatered polyacrylamide emulsions from SNF ha e names starting by DW.In summary, all emulsions are suspens ons of solid particles. Emulsions have a liquid aspect but they are not pure li uids nor liquid blends. Nevertheless they ca

What is cationic paetac & pamptac?

Cationic PAETAC & PAmPTAC were synthesized by UV-induced radical polymerization. New polymers showed good flocculation performance of freshwater & marine microalgae. Optimal doses of PAETAC were 50 and 4.8 mg/g for C. vulgaris & P. purpureum. PAETAC and PAmPTAC produced stable flocs, supporting simple dewatering step.

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.

What type of polyethylene is used for cationic emulsions?

acidic for cationics ;zz and in certain cases, chloride ions oor very poor very poorPolyethylene is used for the transport of emulsions, but the oil has tendency to migrate in low density polyethylene decre sing the drum strength. Treated polyethylene (fluorinated microfibers) are somet mes used
