Sludge Dehydrator Description

The advanced range of sludge dewatering decanter centrifuges is ideal for making significant contributions to a sustainable environment. Its innovative design delivers peak performance at all times while reducing total power consumption by up to 40%. This improvement leads to substantial reductions in CO2 emissions during the sludge dewatering process.

Sludge Dehydrator Process

The initial section of dewatering drum is the thickening Zone, where the solid-liquid separating process takes place and where the filtrate will also be discharged. The pitch of the screw and the gap between the rings decrease at the end of dewatering drum, hence increasing its internal pressure, end Plate further increases the pressure, so as to discharge dry sludge cake.

Sludge is first flow into the Control Tank and then flows down into the Flocculation Tank, Where polymer coagulant is added.

From there, the flocculated sludge overflows into the dewatering drum where it is filtered and compressed. The entire operation sequence, including sludge feed control, polymer makeup, dosing and sludge cake discharge are controlled by the built-in timer and sensors of the PLC.

Sludge Dehydrator Advantages

Low Power Consumption
The screw press operates at a low rotational speed (typically 2–5 RPM), resulting in significantly lower power usage compared to centrifuges or belt presses. This leads to reduced operational costs.

Minimal Water Usage
Unlike belt presses which require a constant flow of wash water to clean belts, it uses self-cleaning rings that reduce water usage dramatically.

Continuous and Automated Operation
Designed for 24/7 operation, IT has minimal operator requirements. Most models include automatic polymer dosing, sludge feeding, and cake discharge systems.

Compact and Space-saving Design
Its compact footprint makes it ideal for plants with limited space. The enclosed design also minimizes odor and improves plant hygiene.

Low Noise and Vibration
With slow operation and fewer moving parts, it generates minimal noise, creating a safer and more pleasant work environment.

High Dewatering Efficiency
Depending on the type of sludge and polymer used, it can achieve solid contents in the range of 18% to 30%, making it competitive with traditional systems.

Sludge Dehydrator Application

Screw press dewatering machines uses a screw mechanism to squeeze and press the material to separate liquids from solids. These machines are suitable for processing animal waste, biogas slurry, paper pulp and other organic materials. The material is fed into the screw press, and as the screw turns, it moves the material along its length. With the decreasing pitch of the screw, the material is compressed. This compression helps to separate the liquid from the solid. The separated liquid flows out through the screen while the solid retains in the screen and continues to move along the screw. And they are finally discharged at end of the machine.
