The “Agència Catalana de l’Aigua (ACA)” has awarded Cadagua with the service of operation, conservation and maintenance and supplies of the Terrassa Wastewater Treatment Plant and the network of collectors, with a duration of 4 years, and a possible additional year of extension. The amount awarded is over 11 million € with the potential extension.
The plant has a treatment capacity of 75,000 m3 / day, through biological reactors, combining suspended and fixed cultivation (IFAS), and another 15,000 m3 /day through MBR, anaerobic sludge digestion, co-digestion and co-generation with an electrical nominal production capacity of 831 kWh. Currently, this plant produces 3,248 MW per year, which would be equivalent to the annual consumption of 1,000 homes.
The technical proposal includes the commitment to the implementation of new generation technologies for the elimination of nitrogen in the different existing flows in the WWTP with a high content of this nutrient. All this seen from the point of view of increasing the overall disposal performance of the installation while optimizing energy efficiency to the maximum.
With this award, Cadagua remains as one of the top companies in wastewater treatment, managing 32 WWTPs with a treated yearly flow of 64,000,000 m3 only in Catalonia.
