Volute Dewatering Press without Sludge Conditioning Tank (GS Series)

1Flow Control Tank
Sludge Conditioning Tank

Sludge feed is regulated with the overflow pipe, returning excess volume to the sludge storage tank.

2Flocculation Tank
Flocculation Tank

Polymer and sludge are stirred and mixed, forming flocks suitable for Volute.

3Cylinder Unit
Cylinder Unit

Sludge is instantly thickened at the thickening zone in the precedent stage, and dewatered at the dewatering zone in the subsequent stage under increasing inner pressure.
*Thickener contains no dewatering zone.
