BACKGROUND: Various methods, including centrifugation, filtration, electroflocculation, flocculation and flotation, have been developed for harvesting microalgae. However, some economic or technical problems still remain with current methods for algal recovery, such as high capital, energy and running costs, flocculant toxicity or low separation efficiency. Therefore, there is great interest in developing new efficient approaches for harvesting microalgae.
RESULT: An efficient electroflocculation method integrated with dispersed-air flotation has been developed for harvesting
Botryococcus braunii. The recovery efficiency of B. braunii reached 93.6% after 30min using an electroflocculation process.
Microalgae recovery was improved significantly when the electroflocculation process was integrated with dispersed-air
flotation; the recovery efficiency of B. braunii reached 98.9% after 14min.
CONCLUSION: The present work demonstrated that electroflocculation integrated with dispersed-air flotation is a promising method suitable formicroalgae harvesting. The strategic air supply obviously shortened the algal recovery time in the process of electroflocculation due to facilitating algal aggregation and flotation to the solution surface. 迅数F200浮游生物计数仪 迅数新F100浮游生物计数仪 迅数Algacount C100藻类计数仪 迅数Z100浮游动物计数仪 迅数Algacount S300藻类智能鉴定计数仪 R100藻类辅助鉴定计数仪 S200藻类智能鉴定计数仪 M500多功能生物监测仪 迅数Algacount M200多功能生物监测仪 M300多功能生物监测仪 菌落计数/筛选/YJ圈测量联用仪 浮游生物/菌落分析仪
