We basically take waste water with algae of our choice in it, and we circulate it through this floating structure, this tubular, flexible plastic structure, and it circulates through this thing, and there's sunlight of course, it's at the surface, and the algae grow on the nutrients.
Metemos lá dentro as águas residuais com as algas que escolhermos e circulamos essa água pela estrutura flutuante, esta estrutura tubular de plástico flexível. A água circula através desta coisa e, claro, apanha a luz solar, porque está à superfície. As algas crescem com os nutrientes.
