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.
Pegamos o esgoto com a alga de nossa preferência, e o circundamos através dessa estrutura flutuante, tubular de plástico flexível, e ela circula através desta coisa, e há a luz do sol, claro, na superfície, e a alga cresce com os nutrientes.
