Demonstrating Nanobubbles Technology for more Sustainable and Efficient Urban Wastewater Treatment
Clean-up of wastewaters is a major problem into all European Countries, as the processes that are currently been used have a high energy demand and produce a big environmental footprint. There are some studies that estimate that around 1% of the global electricity usage in Europe is due to the wastewater treatment plants. This huge electricity consumption has severe consequences, not only in the environment, as the energy consumption is directly related to the Greenhouse gases emissions, but also in the costs of the cleaning up of the wastewater, what limit the installation of new treatment plants and therefore, the volume of wastewater treated, limiting the compliance with the European Directives.
In fact, between the 50% and 60% of the energy demand in an urban wastewater treatment plant is produced by the aeration systems, in the secondary or biological treatment, so it is clear that the improvement of the efficiency of such aeration systems is a key issue that must be addressed urgently.
In this context, the main objective of the LIFE-NANOBUBBLES Project is to demonstrate the technical, environmental and economic feasibility of the innovative Nanobubbles Technology as an efficient, environmentally-friendly and low cost alternative to traditional aerators in urban wastewater treatment plants.
