Abstract (en)
[origin: WO2012123632A1] The present invention relates to the field of wastewater treatment, and more particularly to a method and an arrangement for wastewater sludge treatment in a wastewater sludge handling process. An arrangement for wastewater sludge treatment in a wastewater sludge handling process according to the present invention has a pipe channel (11), through which pipe channel (11) a specified portion of the wastewater sludge is lead through, which pipe channel (11) has a cross section of an essentially regular polygon, and which pipe channel (11) has vibration elements (12-17), (18-21) arranged essentially side-by-side and uniformly bonded to the wall on each side of the pipe channel (11), said vibration elements (12- 17), (18-21) providing a mode of vibration, where essentially all of the side wall of the pipe channel vibrate with a uniform forth and back movement.
