Urban Sustainable Development Solution for Irrigation Systems of Green Spaces Located on Buildings Based on a 3D Catalyst Immobilized on Fixed Support
Résumé
Green spaces located on buildings are an important part of urban environment, improving the quality of life through their aesthetic and functional advantages. However, they consume large amounts of resources from cities' water supply systems. Moreover, rapid urbanization and population growth amplifies the issue on clean water supply, increasing the necessity for efficient solutions enabling wastewater treatment and reuse. This paper focuses on demonstrating of an innovative wastewater treatment method, based on reusable catalyst materials on fixed supports, and their potential application to supply the irrigation scheme of the green spaces located on buildings. The investigations were conducted on a highly persistent organic compound, namely Clofibric Acid, frequently identified in urban wastewater in Europe. The obtained results confirmed that the 3D Hybrid Catalyst has a degradation efficiency of the compound up to 45% in visible light and up to 92% after 7 cycles of reuse, under UV irradiation.
