Prozesu Katalitikoak eta Hondakinen Balioztatzea

Ikerketa Taldea

PROCAT-VARES taldeak energia eta ingurumena oinarri moduan duten ikerketa proiektuen proposamenean, aurrerapenean eta berrikuntzan lan egiten du. Taldearen helburu nagusia gizarterako gaur egun garrantzitsuak diren eta garapen iraunkorrera bideratuta dauden Erreakzio Kimikoaren Ingeniaritzaren ikerketa-lerroak garatzea da nazioarteko mailarik altuenean. Jarduera honen garapenari esker, ikertzaileak eta teknologoak trebatzen dira. Gainera, nazioarteko komunitate zientifiko-teknologikoari jakintza zientifikoa transmititzen zaio interes akademikoa, teknologikoa, soziala eta industriala duten argitalpenen bidez eta industri sektorearekin duen lankidetzaren bidez.

[New paper] Modelling and simulation of subsurface horizontal flow constructed wetlands (Open Access)

As a consequence of the poor implantation of sanitation systems, more than 80% of the wastewater from human activity is dumped, which poses a threat to public health and generates water stress. In contrast, its depuration and reuse for irrigation improves the efficiency of the water management cycle and reduces the use of fresh water. In the context of grey water purification in rural areas of Europe, constructed wetlands are the preferred option. Furthermore, in developing countries, they are particularly attractive as an alternative to conventional purification systems. The design of such facilities tends to avoid the complexity of the interactions between solids, pollutants, microorganisms, and plants. In this work, a more rigorous mathematical model is proposed, which considers the mass balances of the substrate and the microorganisms, in addition to the degradation kinetics typical of biotechnological processes, the life cycles of microorganisms, and their horizontal and vertical transport processes. This model was tuned based on the responses of already installed systems located in Zapote (Costa Rica) and San Salvador (El Salvador). The model foresees start-up times close to three months, in addition to depuration efficiencies reaching above 90%, which corresponds with previously reported values. The developed simulation tool is also employed to study the response of the model to various disturbances, such as punctual stops or seasonal variations in the incoming flow.
