An endless filter belt screen( A ) runs over a drive and guide roller at each and ( B and C ) like a conveyor belt. The upper side of the filter belt screen is supported by several rollers ( D ). 

Filter belt screen ( E ) which above the filter bed runs in the same direction and the same speed. The drive roller for this belt ( F ) is coupled with the drive roller ( B ) of the filter. By means of a pressure roller system the press belt can be pressed on the filter ,  then rollers ( G ) can be individually adjusted horizontally and vertically. 

The sludge to be dewatered ( H ) is fed on the upper face of the filter belt  screen and is continuously dewatered between the filter and press belts. Note how the supporting rollers of the filter belt and the pressure rollers of the pressure belt are applied for such a way that the belts and the sludge between them describe an S - shaped curve. 

This configuration induces parallel displacement of the filter belt screen relative to each other because the difference in radius producing shear in the cake. The sludge is removed by a scraper ( I ) after dewatering in the shear zone .
