① Screw Press

♧ Screw Press is?

• Dehydrator is designed so that sludge entering through
the inlet moves at a constant speed through a screw
that has a decreasing pitch and dehydrated by
a itration part whit decreasing distance.

• This type of structure maintains a certain gap between the exterior
of the screw and the interior of the ring which prevents wear and
tear of the screw and the ring. Additionally due to left and right
rotation of the moving ring, foreign substances in the gap can be
permanently removed.


1. Screw Press ★KS-ST TYPE★

Sludge enters into the bottom of the thickener
in order to be blended by an impeller in it.

• With the process of blending with occulant and ferric sulfate,
compounded sludge moves to the upper side of the thickener.
Floc and residue are being seperated and form to bigger
sludge with spiral ow by the impeller.

• The separated oc and residue are being drained to residual
discharging device which is in the upper central side of thickener.
Concentrated sludge moves into dewatering machine.

♧ Structure
• Thickener
• Multi-Disk Type Screw Press
• Moving Rings & Fixed Rings


2. Screw Press ★KS-RT TYPE★

RT-Type which is suitable for relatively high concentrated sludge,
this type is structure with dehydrator body aggregation
and mixing tank.

• RT-Type's principle is as sludge into the mixing tank's inlet
part by sludge feed pump from the sludge storage tank
and mixing with polymer.

• Sludge flowing into the bottom side of mixing tank is stirred
by an agitator which is installed top of the tank.

• The aggregated sludge will be separated out as floc
and remaining water.
This treated floc and water enter into multi-disk type screw.

• Multi-Disk Type Screw Press
• Moving Rings & Fixed Rings
• Mixing Tank (Coagulation Tank)
