The belt fiter press is widely used in the sludge dehydrating,
however, some problems are being with this machine, such
as the large quantities of water consumption, operation requirement
is high etc. But,the screw type sludge dehydrator is a new
type sludge dehydrator. With its advantages, such as energy saving,
operaton stable, highly automation it is quickly recognized
and accepted by the market.

Advantage
1. One-in-all design, fits in small facility
Multi-plate Screw Press adopted the unified structure that serves
two functions, thickening
and dewatering in the single machinery. The drum filter, because of
the clog-free, realizes
higher speed of filtering phenomena per filtering area as compared
to other methods. For this
reason, low concentration sludge of about Total Solids 0.2%, as
well as thickened sludge, can
be directly fed without pre-thickening.
2. Wide range of line-up/Small footprint
The model of sludge dewatering press based on the customer needs
can be selected from a
wide range of line-up, and can be installed in places where
placement would not be possible
with other technologies for reasons such as low building ceilings
or limited area. This makes
Multi-plate Screw Press suitable to customers who are considering
the replacement of existing
dewatering equipment.
3. Easy operation/Easy maintenance
Full automatic 24-hour operation without an operator on-site is
possible with automatic
operation control using various sensors. With this function, manual
operation, such as starting
or stopping, is not required. Moreover, daily maintenance is
minimized, requires no skilled
labor neither special knowledge, so that everybody can use it
easily.
4. Power and water saving
The screw which is the main component rotates very slowly at a rate
of 2 to 4 rpm, so that it
consumes very low power and thus economical. Multi-plate Screw
Press prevents filter mesh
from clogging with its unique self-cleaning mechanism, removing the
need for huge amounts
of water for clogging prevention.
