Submersible Agitator

The QJB series Submersible agitator is widely used in various types of wastewater treatment plants. Operating while fully submerged, the unit utilizes impeller thrust to agitate the liquid within the tank, thereby keeping solids in suspension, preventing sedimentation, and maintaining sludge activity to a certain extent. It effectively mixes high-viscosity materials found in municipal, agricultural, and industrial wastewater, enhancing microbial reaction efficiency and, consequently, improving overall treatment performance.

High-Speed submersible agitator - Generates directional high-velocity flow at elevated rotational speeds. Ensures continuous hydraulic circulation, activated sludge suspension, and dead zone elimination, stabilizing nitrogen and phosphorus removal. Widely used in anaerobic, anoxic, and aerobic tanks in municipal sewage treatment.

Medium-Speed submersible agitator - The medium-speed submersible agitator strikes an optimal balance between mixing intensity and flow uniformity. It is selected for applications requiring rapid homogenization of influent, equalization of water quality and flow fluctuations, or thorough dispersion and blending of chemicals after dosing. It is commonly installed in equalization tanks, neutralization tanks, and similar structures.

Low-Speed submersible agitator - Features large-diameter impellers that generate gentle, large-volume circulation at low rotational speeds. Suitable for high solids content and high-viscosity applications such as biogas digesters and high-concentration sludge tanks. Effectively prevents sludge settling and breaks surface scum and crust formation without damaging sludge floc structure.

1.Sludge Settling Problems

Solution:Our submersible agitators maintain continuous circulation and prevent solids from accumulating at the bottom of tanks.

2.Uneven Mixing in Treatment Tanks

Solution:The optimized propeller design creates uniform flow distribution and eliminates dead zones.

3.High Solid Content and Viscous Sludge

Solution:Low-speed agitators provide large-volume circulation for sludge tanks and digesters without damaging sludge flocs.

4.Variable Wastewater Conditions

Solution:Adjustable speed control allows operators to optimize mixing performance according to actual process requirements.

• Anoxic / Anaerobic Tanks : maintains sludge suspension, supports nitrogen and phosphorus removal

• Equalization Tanks : homogenizes water quality and quantity, balances influent fluctuations

• Aerobic Biochemical Tanks : promotes water mixing and ensures activated water circulation

• Biogas Digesters / Sludge Tanks : agitates slurry and prevents surface scum and crust formation

• Various Industrial Wastewater Treatment : municipal, papermaking, textile, printing, food processing, and chemical industries wastewater.
