Remaining humidity in the sludge: A problem, which becomes more actual in connection with the height of the disposal costs. Because each litre of liquid recovered from the mud reduces the volume (and thus the disposal costs) of the mud by a kg

The sludge is pulled between the press-band and the main drum and pressed out with a pressure of up to 4 bar. At the end of the (continuous) process, the fixed sludge is stripped by the scrapper falls there into a trash can. 
A patent, fully automatic, electronically controlled tape operation correction prevents the Band from skewing.
