3. Sludge Dewatering Machine

♧ Gravity dehydration section
(1st phase : Initial dehydration)

Condensed sludge in mixing tank is injected into the
charge chute through the inlet pipe and uniformly applied
to the filter cloth. The filtrate flowing through the lower part of
the filter bag is gravity dehydrated and separated from
the filter bag when contacted with the roller for removing
the filtrate attached to the gravity frame. Most of the water is removed here.

♧ Wedge dehydration section
(2nd phase : Low pressure dehydration)

Sludge from phase 1 passes through the area between
the top and bottom of the filter cloth looks like wedge.
The sludge is gradually pressurized to dehydration and
prevent pushed out during high pressure dehydration.

♧ Pressurized dehydration section
(3rd phase : mid pressure dehydration)

The sludge passed through the phase 2 passes through
a number of press rollers specially designed with the inverse
of the diameter principle. The diameter of the pressure
rollers gradually decreases, and the pressure applied to the sludge
increases as the rollers move. The resulting filtrate is effectively
dehydrated without re-infiltration into the sludge.

♧ Gravity dehydration section
(4th phase : high pressure dehydration)

The most important advantages of BPH series high
pressure dehydrator are high pressure rollers on porous
rollers and high pressure belts. The sludge is squeezed by
applying surface pressure to hydraulic syringes, cantilever and
high pressure belt, As an integrated high pressure dehydration
device, complete dehydtration is achieved by simultaneously
applying surface pressure and line pressure.

♧ Internal features

• Cake Discharge
A removable ceramic-type cake outlet that
has resistance to abrasion and great durability.

• Bowl
Capable of processing various materials precisely.

• Reduction Gear
The general-purpose reduction gear that enhance the Centrifuge.

• Screw
Has great resistance to wear on screw with tungsten
carbide welding tips.

• Body
Triangle-shaped body that ensure.

♧ 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.

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

Filter press summary

This is a slurry dehydration machine. The slurry is transferred
to the pressed filter plates by a transfer pump. The filtrate is
dehydrated through the filter cloth, and the solids remain in the
form of a cake in the filter chamber. Components are a main body,
a filter plate, a filter cloth, a filter plate transfer device, a hydraulic cylinder,
a hydraulic unit, a control panel, and a transfer pump.
