Avalon Screw Dehydrator

Advanced Sludge Dewatering Technology by Avalon Separation

The Avalon Screw Dehydrator (ASD) is a next-generation sludge dewatering solution designed to deliver high efficiency, low operational cost, and reliable performance across industrial and municipal wastewater treatment applications.

Developed with advanced engineering and smart automation, the Avalon Screw Dehydrator eliminates common challenges faced in traditional dewatering systems such as clogging, excessive power consumption, high maintenance, and operator dependency.

What is the Avalon Screw Dehydrator?

The Avalon Screw Dehydrator is a fully enclosed, continuous sludge dewatering system that utilizes a slow-speed screw shaft combined with moving and fixed rings to achieve effective solid-liquid separation.

Unlike belt presses, centrifuges, or filter presses, this technology:

Operates at very low RPM
Consumes minimal water and electricity
Requires minimal supervision
Offers clog-free operation

The system gradually increases pressure along the screw shaft, producing high dry solid content with minimal odor and noise.

Why Avalon Screw Dehydrator is Superior

Clog-Free Self-Cleaning Design

The moving and fixed ring structure continuously self-cleans during operation, eliminating blockages and reducing downtime.

Ultra-Low Energy Consumption

Operating at only 2–4 RPM, the system consumes up to 90% less energy than centrifuges and significantly less than belt presses.

No Fresh Water Requirement

Unlike conventional systems, ASD does not require continuous washing water, drastically reducing water consumption.

Compact & Space-Saving Design

Ideal for retrofitting existing plants or installations with space constraints.

Fully Automatic Operation

PLC-controlled automation enables:

One-touch start & stop
Unmanned 24/7 operation
Remote monitoring via SCADA integration

Handles Oily & Fibrous Sludge

Perfect for sludge with high oil, grease, and fiber content.

Key Benefits of Avalon Screw Dehydrator

Low power consumption
Reduced capital investment
Minimal maintenance requirement
High resistance to oily and sticky sludge
No skilled operator required
Odor-free operation
Noise-free working environment
Long operational life
Environmentally friendly process

Automation & System Integration

The Avalon Screw Dehydrator is designed for complete process automation and can be easily integrated with:

Polymer dosing systems
Sludge feed pumps
DAF systems
Conveyors
Central PLC & SCADA

The system supports:

Automatic startup & shutdown
Alarm management
Emergency interruption
Remote monitoring

This ensures maximum safety, reliability, and process optimization.

Direct Dewatering from Oxidation Ditch

Traditional sludge treatment requires pre-thickening before dewatering.

The Avalon Screw Dehydrator eliminates this requirement.

Thanks to its advanced filtration structure, it can process sludge with as low as 0.4% solids concentration, enabling direct dewatering from oxidation ditches without additional thickening tanks.

This results in:

Reduced infrastructure cost
Smaller plant footprint
Lower energy consumption

Clog-Free & Odor-Free Operation

The rotating screw shaft causes continuous separation between moving and fixed rings, preventing clogging.

This also ensures:

No accumulation of solids
No secondary pollution
No unpleasant odors

Ideal for indoor installations and urban environments.

Energy-Efficient Performance

The Avalon Screw Dehydrator operates with:

Power consumption as low as 0.01–0.1 kWh/kg-DS
Up to 20× lower energy usage than centrifuges
Up to 8× lower than belt presses

This significantly reduces operational expenses and carbon footprint.

Compact Design – Small Footprint

The compact footprint allows installation in areas where traditional systems cannot fit.

It is ideal for:

Retrofit projects
Space-restricted plants
Mobile treatment systems

Ideal for indoor installations and urban environments.
