This invention is a construction for processing a fluid, especially for extracting methane gas from the fluid through biological breakdown of the constituents in such. The construction has at least one processing chamber (2a, 2b), one reservoir (1) for the unprocessed fluid, a second reservoir (3) for the processed fluid, a pump device (4) for transporting unprocessed fluid from the first reservoir to the second reservoir, and a heat exchanger (7) to transfer heat from the processed fluid to the unprocessed fluid during said transport. The pump device (4) includes at least 2 work chambers (4a, 4b) and at least one pressure device (50), which varies the volume of the chambers during operation of the pump device. During filling and emptying of the processing chamber and during a work cycle of the pressure device, the one work chamber (4a) is designed to receive unprocessed fluid from the first reservoir (1) and then send such to the processing chamber. The other work chamber (4b) is designed to receive processed fluid from the processing chamber and then send such to the second reservoir (3). Valves (17-24) alternately bring each of the work chambers (4a, 4b) in communication with the processing chamber. One of the reservoirs and the pressure device (50) are designed to during one work cycle vary work chamber volume to the same extent as the amount of fluid that is supplied or led away from the processing chamber.<IMAGE> |
