Conditions of use

In order to ensure the normal operation of the submersible mixer, please select the correctworking environment and operating mode.
a.The maximum medium temperature does not exceed 40’C,
b.The pH range of the medium: 5~9;
c.The medium density does not exceed 1150Kg/m?;d.The diving depth does not exceed 20m.
Special Tips:
Submersible mixers must be fully submerged in water to work, and cannot work in flammableexplosive, highly corrosive or high temperature environments, Our company can provide userswith special designs for special environment requirements.

Application scenarios

1.Wastewater Treatment Plants (Municipal Sewage):

Anaerobic/Anoxic Tanks:​
Performs low-speed mixing to fully blend sewage with activated sludge, preventing sedimentation and creating a favorable environment for microorganisms like denitrifying bacteria.
Oxidation Ditches:
​Propels the mixed liquor to circulate in the ditch, ensuring the activated sludge remains suspended.
Aeration Tanks:​
Used before aeration or in conjunction with aeration systems to promote sludge mixing and improve oxygen utilization efficiency.

2.Industrial Wastewater Treatment:

Widely used in treatment tanks for wastewater from industries such as chemical, pharmaceutical, papermaking, printing/dyeing, and food processing. It mixes and agitates wastewater containing solid particles, fibers, or other impurities to prevent sludge deposition and ensure uniform treatment effectiveness.

3.Other Water Treatment Applications:

Landscape Water Bodies:Used in large landscape lakes, rivers, etc., to increase water fluidity through flow propulsion, preventing eutrophication and avoiding odor generation in dead zones.
Water Supply Treatment: Promotes the rapid and uniform mixing of chemicals with water in coagulation and flocculation tanks.

Operation Mode:

The installation and positioning of the submersible mixer has a great influence on its mixing effect. inorder to achieve the expected operating effect, we recommend that users follow the requirements ofprofessional designers, fully consider the shape of the pool, the location of the water inlet and outletand the vortex caused by the water flow of the mixer reflected to the structure, and try to reduce theshort-circuit cvcle and dead corners, and avoid direct collision with the pool wall to reduce the fowrate. Refer to the following operating mode diagram to help you choose the mixer and installationform reasonably.
