#### The Val Estérel Mediterranean Agglomeration Community, strongly committed to the energy transition of its territory, has entrusted OTV Sud with the implementation of a methanization unit and the valorization of biogas into biomethane at the Reyran water treatment plant in Fréjus. #### CLIENT’S NEEDS - To reduce the volume of sludge and the constraints and costs of disposal - To limit GHG emissions - To produce biogas from sludge and transform this biogas into biomethane that can be injected into the GRDF (French electricity company) network - To produce high quality sludge for the agricultural sector ### THE SOLUTIONS - Integration of an anaerobic digestion unit and biogas valorization into biomethane on an existing site - Complete sludge treatment process: thickening + digestion + centrifugation (existing dehydration) - reducing the volume of sludge to be evacuated by at least 30%. - Biogas valorization: - [MemGasTM](/en/technologies/memgas-archived "MemGas™") membrane technology: state-of-the-art separative technique to purify biogas (64% methane) into biomethane (>97% methane) - Energy recovery: Energido - Veolia's innovative solution for recovering heat from wastewater. The hot water produced keeps the sludge in the digester at 35°C. ### THE ADVANTAGES - **High performance**: 99% of the biogas is transformed into biomethane - **Easy to operate**: fully automated - **Compact**: easy to integrate on an existing site (container) - Reduced carbon footprint: 1500T CO2 equivalent - reduction of road traffic. - Production of green energy generating a significant annual income ### *KEY FIGURES* - *350,000 P.E.* - *10 million m3 of treated wastewater* - *10,000 tons of sludge recovered on site* - *556,000 Nm3/h of biomethane produced* - *6,000 MWh/year produced* - *2,000 households heated* - *750,000 €/year generated by the resale*
