The Bari Ovest purification plant serves most of the city, its industrial area and some neighbouring municipalities. By separating and filtering pollutants, the plant obtains a clear and purified liquid suitable for sea discharge through underground pipelines.

The project plans for the optimization of the sludge pipeline servicing the treatment plant, thanks to cogeneration, a technology that produces the necessary power to heat sludge inside the digestion tanks.

The biofuel produced by the sludge during the digestion phase will be used to feed a cogenerator, that will in turn produce the power used inside the plant and the necessary thermal energy for the sludge heating process.

This technology allows for a sizeable reduction in the power costs currently faced for treatment plant operation, while also reducing the environmental impact generated by thermal plant conventional techniques.
