Electrocoagulation–flotation (ECF) for microalgae harvesting – A review

Harvesting has been recognized as a major bottleneck in any microalgae-based technology, making it a relevant research topic in the field. Among applicable technologies, electrocoagulation-flotation (ECF) has been devoted a lot of attention as an effective alternative to conventional metal salts addition. This paper reports and comments the relevant available literature on ECF, aiming at retrieving and assessing the main parameters affecting...
