Airports and Environment: Proposal of Wastewater Reclamation at São Paulo International Airport

Abstract

One way to reduce water consumption in urban areas is by using alternative sources of supply that can be provided by collecting rainwater and reusing wastewater for less restricted purposes. Thus, this study evaluated the characteristics of effluents produced by the wastewater treatment plant (WWTP) of São Paulo International Airport (SPIA), Brazil, in order to reuse it in non‐potable situations. The results achieved, indicated high efficiency in the biological system utilized by SPIA. The removal rates is equal to or >90% for most of the parameters analyzed, among them, fluoride, salinity, nitrite, nitrate, ammonium nitrogen, total nitrogen, phosphorus, sedimentable solids, turbidity, conductivity, apparent color, chemical oxygen demand, biochemical oxygen demand, total organic carbon, fecal coliforms, and oils and greases. Despite the final effluents were good enough to be launched in the local streams, they shall be submitted to a complementary treatment in order to fit some quality parameters to be reused for specific demands (landscape irrigation, toilet flushing, vehicle washing, fire fighting, and dust control).

Optimizing Airport Runway Capacity and Sustainability through the Introduction of Rapid Exit Taxiways: A Case Study

“…Research on airport sustainability is actually increasing, despite the fact that the interest of most authors is focused on global greenhouse gas emissions from airfield pavements and energy management strategies for airport buildings [25][26][27][28][29][30][31][32][33][34]. Less attention is given to other issues, such as water conservation [35][36][37][38][39], climate change resilience and weather resilience [40][41][42][43], and waste management [44][45][46].…”
