Prototype at Kaja Student Dormitories in Norway
The Norwegian University of Life Sciences (UMB) follows the vision of a zero-emission campus. A first step towards this vision has been realized at Kaja Student Dormitories that have been equipped with a source separating sanitary system. Water from kitchen and washing facilities is collected separately and treated in a constructed wetland.
Less water consumption
Jets™ vacuum toilets are providing the students the same bathroom comfort as at home at 20% of the water consumption of a conventional toilet system. The blackwater (wastewater from toilets) is pumped to the UMB environmental test and demonstration laboratory where it can be used for different experiments and prototype testing. UMB is a Nordic competence centre for ecological sanitation.
Membrane technology
The SANBOX prototype to be tested at the Kaja Student Dormitories will be a novel solution for the numerous weekend houses and tourist lodges over the whole of Scandinavia. Due to the northern latitude, Scandinavia differs from the Alps and the Mediterranean area and solar radiation will not be sufficient to evaporate wastewater. The prototype at Kaja Student Dormitories will therefore focus on high treatment performance using membrane technology to reach excellent effluent quality with low energy consumption. Solid residues will be composted so that they can be reused for local agriculture
