The VoR Sludge Dehydrator brings revolutionary technology to sludge
This process has made possible the direct dewatering of low concentration
oxidation ditch or waste activated sludge. The already proven superior
performance of the Sludge Dehydrator is the result of joint research
by the developers of the technology with the Japan Sewage Works
The unique design of the Sludge Dehydrator allows 24 hr unattended
operation 7 days per week, eliminating the need for larger and more
expensive dewatering plants that can only be operated 7 hours per
day 5 days per week.
The Sludge Dehydrator consists of a series of aligned rings with
a variable pitch auger running through their center.
Every second ring is fixed to a barrel assembley and seperated
by spacers. Intermediary rings are free to move. The internal diameter
of the fixed rings is larger than the diameter of the auger. The
intermediary rings have an internal diameter slightly less than
the auger and hence are moved in an orbital motion as the auger
The movement of the intermediary rings constantly cleans the barrel
assembly allowing free drainage of water.
This arrangement allows for extremely low power
Dilute sludge is introduced into a flocculator tank at the rear
of the unit and mixed with a polymer solution to produce floccs.
The floccs overflow into the barrel and are drained of free water
as they are transported along the auger.
Final compression of the sludge cake at the end of the auger is
enhanced by decreasing both the pitch of the auger and the spacing
between the fixed and intermediary rings.
This arrangement eliminates the need for high pressure sprays and
any accompaning noise and “misting” that is always a problem
with the use of spray systems.
