Comparison between costs, application and surfaces (R. Cervera and J. Pioz)
We present a real project designed to be built on the outskirts of Madrid, is an
urban fountain to be implanted in a roundabout. It is a type Open Pond photo-
bioreactor formed by circular ponds with stirring blades in the centre to ensure the
movement of the crop. The source also has decorative elements that in turn work
with the operation of the photo-bioreactor as water curtain arches with LED lights
(Fig.
7.14
).
The source moves a volume of 23 m
3
of water with algae and achieves bio-
fixation every year to about 337 kg/year, which represents emissions of a gasoline
car that travels at about 1,700 km (Fig.

).
