The contract works to rehabilitate the Paredes de Coura Wastewater Treatment Plant aims to double the treatment capacity of the unit.
Currently the existing biological treatment aeration system does not meet the current needs of aeration in high season, and does not allow fine control of the treatment process and its energy consumption.
Furthermore, the equipment has reached a useful life of 15 years. Therefore, a new diffused air injection system fed by air compressors will be installed, and the construction of a new building is planned for this purpose.
It is also planned to replace the groups of pumps for recirculation and extraction of sludge from biological treatment, the group for lifting the effluent from septic tanks, the group of service water booster and respective network to the dehydration building, and the automatic unit for preparation and dosing of polyelectrolyte, and respective dosing pumps and dilution panel.
It is also contemplated the reinforcement of the sludge dewatering stage, through the installation of a sludge dewatering centrifuge, in order to adapt the extraction of sludge to the current production of WWTP sludge in peak season, which is undersized.
