The innovative technology is composed of an instrument (LESSDRONE) for monitoring the oxygen transfer efficiency (OTE) in operating conditions and a user-friendly protocol for converting complex process information in actions aimed at minimizing WRRFs CFP and energy demand.
The reduction of energy costs and the minimization of GreenHouses Gases (GHGs) emissions, complying with the quality effluent limits, will improve the environmental and economic sustainability of WRRFs while reducing associated costs for citizens and industries.
The applicability and the suitability of the innovative tool will represent a crucial issue of the project in order to ensure the transferability to other WRRFs also operating in different contexts and industrial sectors.
In July 2020, the first of the 2 measurement campaigns planned at the San Colombano WRRF was completed. The campaign, which was intended to measure oxygen transfer and the production
Action B4 continues: Development of the protocol for the reduction of energy consumption and greenhouse gas emissions. The biokinetic and hydrodynamic models have been implemented by UNIFI and UGENT respectively,
A scientific article on the experimentation carried out in the Lesswatt project has been published in the technical-scientific journal with free consultation Ingegneria dell’Ambiente (n.2 / 2020). The article can
Aerobic activated sludge processes are the most used technology for wastewater treatment. Therefore, the optimization of the oxygen transfer process can significantly reduce energy costs and Carbon FootPrint (CFP).
The innovative technology foresees the implementation of a protocol, a model based user-friendly tool, which integrates data from the LESSDRONE, processes information and external inputs, and translates these in applicable actions aimed at minimizing CFP footprint.
The size of the plant is significant from both organic load and influent flow point of view. The protocol optimization in different WRRFs around Europe will ensure the transferability of the technology. The innovative tool will be implemented and optimized during the project activity in 3 Italian WRRFs (S.Colombano, Tuscany; Sestri Ponente, Liguria and Roma est, Lazio) and 2 north European WRRFs (Eindhoven and Tilburg, The Netherland).
