Preliminary Study on Harvesting Dunaliella salina Cells by Foam Flotation Technique
盐藻细胞泡载分离法采收的初步研究

By determining the enrichment factor and total yield of Dunaliella salina cells, the effects of different operational conditions, such as gas flow rate (vg), initial cell concentration (C0) and pH on the feasibility of foam flotation of Dunaliella salina cells were investigated. By the way, the treatment conditions were optimized. The experimental results showed that when vg was 60 ml/min, C0 was 2.58105 cells/ml and pH was 7.5, foam flotation had a high concentrating efficiency for total yield (90%~94%) and the enrichment factor reached 30~34. The foam flotation may be a simple and highly effective method for concentrating Dunaliella salina cells.
