With the help of Triglav National Park administration we found out that local users collect water from the naturally occuring springs because they believe that water is healthier than tap water. In order to enable that behavior we wish to offer filtration systems by developing a prototype based on ceramic filtration.

The final product Dodola is an installation of intricately shaped filtration modules which purifies water of contaminants as small as bacteria.

Dodola is multitude more efficient than already available ceramic filters, because of the used technologies and principles such as gyroid structure and archimedes screw. The filtration system is self-operating and doesn’t need constant maintenance.
Dodola is a pagan tradition found in the Balkans, South Slavs used to organise the Dodola / Perperuna festival in times of drought, where they worshipped the goddess named Dodola and prayed to her for rain.
The objects are mostly submerged underwater where porous structure filters water as it passes through the material. Because of the rivers flow the objects rotate, and by doing so transport the water towards the upper part of the module, where it leaves the system to be used as potable water.

To increase the permeability of water, the filter was designed by incorporation of the gyroid minimal surface, which can be observed in beetle shells and paths of butterfly’s wings mid flight.

The structure used in the water filter increases the area of water permeability by a manyfold, which consequently accelerates the water filtration. Furthermore using this structure makes the objects statically reinforced.

We use the flow of the river to turn the filter with an archimedes screw, which then transfers the water from lower to higher plane. By using the flow of water to power the rotation of the filter the object can be installed even in remote areas where there are no power connections.

Water travels up.
