Depuración alternativa, con aporte térmico de energía solar

SUMMARY The location of the Balearic Islandsʼ University Campus, isolated from the city of Palma, has made possible the construction of an on-site wastewater treatment plant to remedy the scarcity of water. The plant runs with natural wastewater systems mixing three well known technologies: waste stabilization ponds, constructed wetlands and tree fi lters. The innovation in this fi eld is done by a thermal regulation to avoid the destratifi cation events that causes bad odours in the main pond. It involves taking advantage of the residual heat of solar air-conditioning facilities installed in a nearby building. The residual heat is used to increase the stratifi cation on the pond to avoid the thermal destratifi cation.
