The product, Dodola, is an installation of intricately shaped filtration modules which purify water of contaminants as small as bacteria. It’s made of clay, mixed with organic material and fired in a way which increases its porosity. It is many times more efficient than already available ceramic filters because of the used technologies and principles such as the gyroid structure and Archimedes screw. The filtration system is self—operating and doesn’t need constant maintenance. The objects are mostly submerged underwater where the porous structure filters water as it passes through the material. Because of the river’s 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 incorporating the gyroid minimal surface, which can also be observed in natural phenomena — such as beetle shells and crystal structures. The structure used in the water filter increases the area of permeability by a manifold, which consequently accelerates the water filtration. Furthermore, using this structure makes the objects statically reinforced. The flow of the water is used to turn the filters, which then transfer the water from a lower to a higher plane through an Archimedes screw. By using the flow of water to power the rotation of the filters, the device can be installed in remote areas where there are no power connections. The product was developed under the Museum of architecture (MAO) for the Biannual of design BIO27.
PJORKKALA, a group of three students of Industrial design and two students of Graphic design, studying at the Academy of Fine Arts and Design in Ljubljana, who are working with experts from different fields. As a group of different individuals, they are connected by an interest in environmental and social issues and potential solutions with which they could co—create the future. Each member is trying to integrate the mentioned principles into projects. One example of that was the challenge of reverse logistics, which was focused on research on the topic of food waste in Slovenia. The project was on display at Dutch Design Week in Eindhoven and was part of Barcelona Design Week and Expo in Dubai. Another example is the project which was designed for the Biennial of Design in Ljubljana (BIO27). They were tackling the topic of water contamination in Slovenia and were trying to implement vernacular principles in work. The latest project is a collaboration with the Floating University, Berlin for the Tbilisi triennial where they are going to be presenting a filtration device. They consider these kinds of projects as essential to achieving positive changes, furthermore, they believe that the field of design is marked by the fact that it lies at the crossroads between the humanities and sciences, therefore giving the skills required to coordinate both sides which are crucial in the context of solving problems.
