CORPI GIA has executed the project of replacing a centrifugal decanter for the dehydration of secondary sludge at the wastewater treatment plant in Olot, through a public tender by the Consell Comarcal de la Garrotxa.

The centrifuge installed by CORPI GIA has a dehydration capacity of 40 m³/h at 2.5%, resulting in a mass load of 1000 kg/h. The chosen centrifuge is a GEA machine with dual motors regulated by frequency inverters, which allows optimizing the dehydration result by maximizing dryness and improving the reject water. Among other features, the centrifuge has an automatic lubrication system, bearing temperature control and a vibration level detector.

The dehydrated sludge reaches a dryness greater than 18%.
