Abstract: Apparatus for treatment of wet organic matter to produce biogas, comprising a closed reactor (11) for anaerobic digestion of the wet organic matter. The anaerobic reactor comprises two vertical 5 tubes, a vertically arranged outer tube (14) defining a first reactor chamber (111) enveloping a vertically arranged inner tube (15) which is divided into a first region (112a) and a second region (112b) of a second reactor chamber (112) by a vertical partitioning wall (16). The first reactor chamber comprises a particle retaining unit (31) connecting the first and the second reactor chambers. The anaerobic reactor (11) exhibits a top discharge pipe (18) for gas developed in either 0 of the two reactor chambers (111, 112). A method for treatment of wet organic matter is also contemplated.

Abstract: The invention relates to a process for reducing the amount of sulphur compounds in a sulphur compounds contaminated wastewater stream, using a granular sludge treatment system (10) comprising anaerobic microorganisms, wherein the process comprises the steps of adding an aqueous nitrate solution to the wastewater stream, contacting the wastewater stream with the anaerobic microorganisms, and anoxic oxidation of at least part of the sulphur compounds in the sulphur compounds contaminated wastewater stream by the anaerobic microorganisms, resulting in a sulphur compounds depleted wastewater stream. The invention furthermore relates to such a granular sludge treatment system (10).
