Abstract:
1. A device for treating percolate recovered from a biomass fermenter which comprises at least one fermenter ( 13 ) and a percolate tank ( 10 ) for collecting the percolate from the at least one fermenter ( 13 ), wherein the percolate tank ( 10 ) has a percolate inlet ( 10 c ) fluidly coupled to an outlet of the at least one fermenter ( 13 ) and configured for receiving percolate from the at least one fermenter ( 13 ), and a percolate outlet ( 10 b ) fluidly coupled to said percolate inlet ( 10 c ) of the percolate tank ( 10 ) by means of a flow path (P), characterized in that the flow path (P) in the percolate tank between the percolate inlet ( 10 c ) and the percolate outlet ( 10 b ) is configured in the form of a non-direct, extended flow path (P) selected from the group of flow paths consisting of a meander path, a spiral path and a helical path, said non-direct extended flow path (P) having a predetermined length and configured for providing an extended flow path (P) for said percolate received from the at least one fermenter ( 13 ), for providing a sufficiently long dwell time for the percolate at a thermophilic adapted temperature, the predetermined length of the flow path of the percolate and the temperature of the percolate along the extended flow path between the percolate inlet ( 10 c ) and the percolate outlet ( 10 b ) configured such that only sanitized percolate is drawn off at the percolate outlet ( 10 b ).
