  • METHOD AND DEVICE FOR THE TREATMENT OF ORGANIC MATTER USING THICKENING AND THERMAL TREATMENT
    Publication number: 20170313612
    Abstract: The present invention relates to a method for the treatment of organic matter, in particular sewage sludge, comprising the following steps: The organic matter is first thickened to increase the solids concentration. The thickened organic matter is supplied directly into a digester. The organic matter is then removed from the digester by way of a recirculation line, thermally treated and returned to the digester. The invention further relates to a device for the treatment of organic matter, in particular sewage sludge, comprising a digester, a thickener and a recirculation line, where the thickener is arranged upstream of the digester, and the recirculation line is designed to supply organic matter from the digester directly to the thermal treatment device, and to return the treated organic matter to the digester.
