Table 2 Comparison of microalgal harvesting techniques for protein production
Method | Efficiency | Energy demand | Cost | Suitability for large-scale production | References |
|---|---|---|---|---|---|
Sedimentation | Low | Low | Low | Suitable for dense cultures with high settling velocity | [43] |
Centrifugation | High | High | High | Suitable for high-value applications | [44] |
Filtration | Moderate | Moderate | Medium | Effective for large-cell algae but prone to clogging | [45] |
Flotation | Moderate | Moderate | Medium | Effective but requires chemical additives | [46] |
Flocculation | High | Low to Moderate | Low | Cost-effective but may introduce impurities | [47] |
