01. Product Overview

KEHENG Slow Speed Mixer for Wastewater Sludge Treatment is designed for industrial wastewater treatment facilities, municipal sewage plants and sludge processing systems requiring reliable and controlled mixing performance. This industrial sludge mixer helps maintain uniform solids distribution, reduce unwanted sediment accumulation and support consistent process conditions in treatment tanks.

Unlike applications that depend on high-speed turbulence, slow speed mixing focuses on controlled fluid movement and bulk circulation. The agitator can be configured according to tank dimensions, sludge concentration, rheological properties and the required process objectives.

As an industrial agitator manufacturer, KEHENG provides customized mixing equipment for new installations, process upgrades and suitable replacement applications across the wastewater treatment industry.

02. Key Features and Benefits

03. Working Principle and Mixing Performance

The slow speed industrial agitator transfers mechanical power from the motor and gearbox to the agitator shaft and impeller. As the impeller rotates, it generates fluid flow that promotes circulation and distributes suspended solids within the tank.

Depending on the process conditions, the wastewater sludge mixer can be designed to support the following objectives:

• Sludge Homogenization: Promotes a more uniform distribution of solids and liquid phases.

• Bulk Fluid Circulation: Encourages movement throughout the effective mixing zone.

• Suspended Solids Management: Helps reduce sedimentation where the selected mixing intensity is sufficient.

• Process Consistency: Supports more uniform tank conditions for subsequent treatment and transfer operations.

Engineering note: Actual mixing performance depends on sludge concentration, viscosity, yield stress, tank geometry, impeller configuration and operating speed. Final selection should be based on the specific process requirements.

04. Wastewater Treatment Applications

05. Engineering Considerations for Mixer Selection

Selecting a slow speed mixer requires more than determining motor power or rotational speed. Wastewater sludge can exhibit complex flow behavior, particularly at high solids concentrations. A suitable agitator must be evaluated against both process performance and mechanical requirements.

Sludge Characteristics

Solids concentration, viscosity, yield stress, temperature and composition influence the resistance encountered by the impeller and the circulation pattern developed in the tank.

Tank Geometry and Impeller Configuration

Tank diameter, liquid depth, bottom profile, internal obstructions and inlet or outlet positions should be considered when determining impeller diameter, mounting position and operating speed.

Motor, Gearbox and Torque

The drive system should be selected according to calculated power demand, required torque, starting conditions and operating duty. Low rotational speed does not automatically mean low torque demand.

Material and Corrosion Resistance

Carbon steel or suitable stainless steel grades may be considered according to chemical composition, corrosion potential, abrasive solids and maintenance requirements.

Operating Objectives

Solids suspension, homogenization, chemical blending and sediment control may require different mixing intensities. The design should reflect the actual process objective rather than a generic mixer specification.

06. Customized Wastewater Sludge Mixing Solutions

KEHENG develops industrial agitator solutions according to project-specific operating conditions. For wastewater sludge applications, customization may cover the drive unit, shaft dimensions, impeller arrangement, wetted materials, mounting structure and installation interfaces.

For new projects, KEHENG can coordinate agitator design and manufacturing with the available process data. For existing facilities, the mixing arrangement can be reviewed to address inadequate circulation, sediment accumulation, unsuitable drive selection or equipment replacement needs.

07. Technical Information Required

To evaluate a suitable wastewater sludge mixer, please provide the following information where available:

If some parameters are unavailable, preliminary evaluation may begin with the existing process data. Final selection is subject to confirmation of the critical operating and mechanical requirements.

08. Why Choose KEHENG Mixing?

A reliable sludge mixing system requires coordinated consideration of process conditions, mechanical design and installation requirements. KEHENG combines industrial agitator manufacturing experience with application-oriented engineering to support different wastewater treatment projects.
