In this study, an efficient electro-flocculation process for Dunaliella salina with energy production by aluminum-air battery has been successfully applied. The formed aluminum hydroxide hydrates during discharging of battery were positively charged, which have a great potential for microalgae flocculation. The precipitation of aluminum hydroxide hydrates by algae also could improve the performance of aluminum-air battery. The harvesting efficiency could reach 97% in 20mins with energy production of 0.11kWh/kg. This discharging electro-flocculation (DEF) technology provides a new energy producing process to effectively harvest microalgae.
在这项研究中，成功应用了一种高效的电絮凝工艺，利用铝空气电池来生产能源，对杜氏盐藻进行处理。电池放电过程中形成的氢氧化铝水合物带正电荷，对微藻絮凝有很大的潜力。藻类对氢氧化铝水合物的沉淀也可以改善铝空气电池的性能。通过 20 分钟的沉淀，收获效率可以达到 97%，能量产量为 0.11kWh/kg。这种放电电絮凝（DEF）技术为有效收获微藻提供了一种新的能源生产工艺。
