• Resumen

  • Composting is a very effective process in waste treatment. Very good results are obtained in mass and volume loss, moisture reduction, organic matter stabilization as well as making possible agricultural uses for the final product. Some parameters as nutrients (C/N ratio), pH, temperature and oxygen content are pointed as the most important for the process. Some composting systems are mentioned but finally tunnel system is shown as the best. Its great advantage is that measurements from main parameters are given continuously to the control comuter, so process optimization is done at the moment. The Vila-Seca sludge composting plant is described. This plant can treat 30.000 tones/year from three water treatment plants. The expected 50% on organic matter reduction and 70% on dry matter content has been achieved after only 3 months since it starting up. Finally, in September 1995 will start the construction of another sludge composting plant were the same technology, belonging to GICOM and represented by G.T.R. in Spain, will be installed.
