<p>Organic material having a high bacteria concentration in an aqueous medium, is subjected to an aenerobic conversion, in order to abtain methane gas and valuable bacteria sludge. Said conversion occurs in a fermentation vessel (1) comprising a plurality of successive superimposed precipitation spaces (5, 5a, 5b, 5c), each space comprising a gas outlet (6) and a sludge outlet (11). The precipitation spaces are surrounded by an annular fermentation vessel-space (9).</p> |
