HAUS DDE Series Decanter Centrifuge for Wastewater Treatment and Sludge Dewatering

What Is the HAUS DDE Series Decanter Centrifuge?

The HAUS DDE Series Decanter Centrifuge is an industrial centrifugal separation system designed for municipal and industrial wastewater treatment, sludge dewatering and potable water treatment applications.

The DDE Series features a horizontal rotating bowl, two-phase separation configuration, continuous solids discharge and a dual-drive system with variable differential speed.

By separating suspended solids from liquid streams, the equipment supports sludge concentration and dewatering processes in wastewater treatment facilities.

How Does the DDE Series Decanter Centrifuge Work?

The DDE Series operates using centrifugal force generated by a horizontal rotating bowl.

During operation, suspended solids are separated from the liquid phase and move toward the bowl wall. An internal screw conveyor continuously transports the separated solids toward the discharge outlet.

The clarified liquid is discharged separately, allowing continuous solid-liquid separation within the wastewater treatment process.

The dual-drive system with variable differential speed allows the relative speed between the bowl and screw conveyor to be adjusted according to sludge characteristics and separation requirements.

Wastewater Treatment and Sludge Dewatering Applications

The HAUS DDE Series is designed to support solid-liquid separation requirements in water and wastewater treatment processes.

• Municipal Wastewater Treatment: Dewatering of sludge generated during municipal wastewater treatment processes.
• Industrial Wastewater Treatment: Separation and concentration of solids from suitable industrial wastewater streams.
• Sludge Dewatering: Removal of liquid from sludge to increase the concentration of discharged solids.
• Potable Water Treatment: Treatment and dewatering of residual sludge generated during drinking water purification processes.
• Wastewater Sludge Management: Separation of liquid and solid phases to support subsequent sludge handling and disposal operations.

Municipal Wastewater Sludge Dewatering

Municipal wastewater treatment plants generate sludge containing water and suspended solid materials.

The DDE Series Decanter Centrifuge separates liquid from sludge through centrifugal force, increasing the concentration of the discharged solid phase.

This process can reduce the volume of water retained in sludge and support more efficient sludge handling, transportation and disposal.

Industrial Wastewater Treatment Applications

Industrial wastewater streams can contain suspended solids and other process residues that require separation before further treatment or disposal.

The HAUS DDE Series can be integrated into suitable industrial wastewater treatment processes to separate solid materials from the liquid phase.

The appropriate equipment configuration depends on the characteristics of the wastewater, solid concentration, required throughput and treatment objectives.

Potable Water Treatment and Residual Sludge Processing

Potable water treatment facilities can generate residual sludge during clarification and purification processes.

The DDE Series supports the dewatering of suitable water treatment sludge, separating liquid from the solid phase and increasing the concentration of discharged material.

This separation process can support subsequent sludge handling and treatment operations.

Continuous Processing and Sludge Dewatering

The HAUS DDE Series is developed for continuous processing of wastewater sludge and other suitable solid-liquid mixtures.

The equipment combines centrifugal separation with continuous solids discharge, supporting processing operations across small, medium and large wastewater treatment facilities.

Achievable separation performance and sludge dryness depend on sludge composition, operating conditions, polymer conditioning and selected centrifuge configuration.

Advantages of the HAUS DDE Series

• Continuous Operation: Supports continuous processing of suitable wastewater and sludge streams.
• Solid-Liquid Separation: Uses centrifugal force to separate suspended solids from liquids.
• Sludge Dewatering: Increases the solids concentration of discharged sludge.
• Dual-Drive Technology: Enables differential speed adjustment according to process requirements.
• Sludge Volume Management: Can reduce the amount of liquid retained in discharged sludge.
• Application Flexibility: Supports municipal, industrial and potable water treatment applications.
• Process Integration: Can be incorporated into suitable wastewater treatment and sludge management systems.

How to Select the Right DDE Series Decanter Centrifuge

Selecting the appropriate DDE Series Decanter Centrifuge requires an evaluation of the wastewater treatment process and sludge characteristics.

Important selection criteria include sludge flow rate, solids concentration, particle characteristics, required dryness, liquid clarification objectives and operating conditions.

The appropriate centrifuge model and operating configuration should be determined according to the technical requirements of the treatment facility.

DDE vs. DDF vs. DDI Decanter Centrifuges

HAUS offers different decanter centrifuge series developed for specific industrial separation applications.

• DDE Series: Designed for wastewater treatment and sludge dewatering applications.
• DDF Series: Developed for food and beverage processing, including juice clarification and pulp dewatering.
• DDI Series: Intended for demanding industrial applications, including chemical processing, mining, oil and gas, and material recovery.

The selection of the appropriate series depends on the characteristics of the processed material and the objectives of the separation process.
