How it works
The Z3900 is characterised by its step-by-step movement. The
drive bar moves forward and returns, the blade being fastened to
a slide that is moved forward stage by stage by the drive bar.
A system of levers on the slide changes its direction of movement
when it reaches its end position. This means that it is possible to
install several blades in series in one tank, the scum being passed
from one blade to the next on its way to the scum pipe.
Drive
Bar

Each blade is angled upwards 90° during its return.

To obtain maximum scum dry solids content, the Z3900 should
be combined with a Z6300 or Z6500 scum pipe or a Z6900 scum
beach.
