New publication: electrocoagulation with an agricultural twist


Electrocoagulation is a process that involves the application of an electrical current to a solution containing microalgae, to harvest them. It is a promising method for microalgae harvesting due to its effectiveness, low energy consumption, and environmental friendliness. However, the sacrificial electrodes release salts to both the media and the harvested biomass, so it is important to chose your electrodes wisely! In this study, the effects of Fe, Zn, and Mg electrodes were evaluated on Nannochloropsis oceanica harvesting and, through elementary composition of biomass and supernatants, the salts bioavailability was assessed. Finally, the minerals were shown to be bioavailable for Solanum lycopersicum.
