- Which polyacrylamide is best for flocculation?
- Cationic polyacrylamides performed the best in terms of high flocculation efficiencies and low optimum flocculant doses.
- What is the maximum flocculation efficiencies of polyacrylamide?
- In general, the maximum flocculation efficiencies recorded for all polyacrylamide variants ranged from 94 to 100% for flocculant doses varying from 45 mg/L to 1.66 mg/L, respectively, for freshwater Chlorella vulgaris suspensions.
- Can cationic polyacrylamides trigger microalgae flocculation?
- Effective flocculation performance may be achieved at salinity concentrations below 5 g/L . The diminishing competence of cationic polyacrylamides to trigger microalgae flocculation in marine and brackish media is attributed to the coiling of polymer chains under high ionic strength conditions.
- Why is polyacrylamide-microalgae flocculation important?
- Flocculation is the most versatile, energy-efficient and cost-efficient harvesting process. Polyacrylamides exhibit high harvesting performance at different operation scales. Comprehensive analysis of polyacrylamide-microalgae flocculation was presented. Properties of polyacrylamide and microalgae culture influence the flocculation process.
