In many sludge treatment projects, the real challenge is not choosing a machine —
it’s understanding the operating conditions behind it.
In one project, sludge concentration fluctuated significantly, space was limited, and stable operation mattered more than peak capacity.
Instead of locking in equipment too early, the system was evaluated as a whole: sludge characteristics, process layout, and long-term operation.
The result was not just equipment that “works”, but a system that runs steadily with lower operational risk and lifecycle cost.

Struggling with high sludge disposal costs or unstable dewatering performance?

An efficient sludge dewatering system can significantly reduce:• sludge volume• hauling costs• polymer consumption

Our sludge dewatering solutions are designed based on actual sludge characteristics, not assumptions — whether for municipal wastewater or industrial applications.

✔ Compact footprint✔ Stable operation✔ Low operating cost✔ Suitable for continuous operation

If you’re planning a new project or upgrading an existing WWTP, selecting the right dewatering technology makes a real difference.

Sludge treatment is not just about choosing a machine.
In many projects, operating issues appear not because of equipment quality,
but because sludge characteristics were not fully considered at the beginning.
Solids concentration, variability, upstream processes, and space limitations
all affect long-term performance.
A system-based approach usually results in:
more stable operation
lower operating cost
easier maintenance over time
📌 Equipment works best when it fits the process — not the other way around.

In sludge treatment projects, choosing equipment too early often leads to higher operating costs later.

In many projects, equipment is selected before sludge characteristics are fully understood.
Factors like solids concentration, sludge variability, and footprint constraints are often underestimated.

A system-based evaluation usually leads to more stable operation and lower lifecycle cost.

Drum thickener-dewatering systems are often applied when sludge concentration is low
and stable, continuous operation is required.

By integrating thickening and dewatering into one unit,
the system helps reduce footprint and simplify upstream sludge handling.

Typical applications include:
• Municipal wastewater treatment plants with low MLSS
• Sludge lines with limited space
• Projects where operational simplicity and automation are priorities

As with any sludge handling solution,
equipment selection should be based on sludge characteristics and overall process design rather than a single performance parameter.

In sludge dewatering projects, equipment type is often decided too early.
Many projects start by comparing belt presses, screw presses or centrifuges.
But in practice, the final performance is usually determined by factors beyond the machine itself.
From engineering experience, three points are often underestimated:
1️⃣ Sludge concentration before dewatering
Low or unstable inlet concentration can limit any dewatering equipment, regardless of brand or type.
2️⃣ Upstream process stability
Fluctuations in flow rate and solids loading often explain why the same equipment performs very differently across projects.
3️⃣ Operation & maintenance capability
A technically “advanced” solution may not be the most reliable one if daily operation conditions are ignored.
In many cases, the optimal solution is a system-level decision, not just a machine selection.

Volute Screw Press for Sludge Dewatering

A volute screw press (multi-disc screw press) is a sludge dewatering device widely used in municipal and industrial wastewater treatment plants, especially in projects requiring stable operation and low maintenance.
The equipment adopts a screw shaft combined with fixed and moving rings, forming a continuous self-cleaning structure. During operation, sludge is gradually thickened and dewatered under increasing pressure, allowing water to be discharged while reducing clogging risks.
Compared with belt filter presses, volute screw presses feature compact design, low washing water consumption, and enclosed operation. They are particularly suitable for oily sludge, low-concentration sludge, and facilities with limited space or low operator availability.

✔ Low water consumption
✔ Continuous automatic operation
✔ Suitable for oily and biological sludge

Belt Filter Press for Sludge Dewatering

Sludge dewatering plays a key role in wastewater treatment, as it directly affects sludge disposal costs and overall plant operation efficiency.

A belt filter press is a continuous mechanical dewatering device widely used in municipal and industrial wastewater treatment plants. After proper flocculation, sludge is evenly distributed onto moving filter belts and dewatered through gravity drainage, wedge zone compression, and high-pressure squeezing.

Due to its stable operation, high treatment capacity, and relatively low energy consumption, belt filter presses are especially suitable for large-scale sludge dewatering applications.

✔ Continuous and stable operation
✔ High sludge throughput
✔ Low energy consumption
✔ Easy operation and maintenance

Belt Press VS Screw Press
Belt Press:
• Large treatment capacity
• Suitable for high-flow municipal or industrial plants
• Lower investment cost, but requires more washing water and maintenance

Screw Press:
• Compact and enclosed design
• Low washing water consumption
• Ideal for oily sludge, low-concentration sludge, and unmanned operation scenarios
