Vortex Grit Removal System

LIGR Series Swirling Flow Grit Removal System

Exported to USA  High Efficiency Grit  Removal  System 0

1. Applicant

It Is Mainly Used In The Swirling Grit Settling Pond Of The Urban Sewage Treatment Plant. This Equipment Uses Hydraulic Swirling To Effectively Separate the Mud Grit And Organic Matter. It Is Ideal Grit Removal Equipment.

 

2. Structure and Working Principle

The Swirling Grit Removal Pool adopts a cone-bottomed round pond with an Impeller Separator Installed in the Pond. After the sewage flows from the pond tangentially, it rotates 270 degree (clockwise as viewed from the top) and the sewage is discharged from the drainage channel by utilizing a certain flow rate of incoming water as power. It will make tangential movement along the inner wall of the circular Grit pool to form a swirling flow. At the same time, the liquid swirling and axial vortices are stirred by the paddles, thereby accelerating the sedimentation of the Grit particles in the sewage and effectively separating the organic matter from the Grit particles.

 

 

The smaller the central water flow section is, the faster the water flow speeds is, and the bottom water flow speed is increasing in the center. Move the Grit on the bottom of the pond to the central Grit bucket in a spiral trajectory. Organic matter rises in the center of the pond and the organic matter will be discharged together with the water flow. The bottom settling Grit is boosted by a lifting device, and then enters into the Grit separator for Grit-water separation, while the sewage returns to the Grid or Screen well.
