Sludge requirements and characteristics of the scraper

In the process of operation, the scraper drives the scraper to rotate around the center of the sedimentation tank through its driving device. After the raw water is effectively precipitated through the sedimentation tank during operation, the supernatant liquid is discharged from the overflow raft. The sludge deposited on the bottom of the tank is slowly pushed along the bottom of the pool to the central mud collecting tank and pushed out through the draining pipe under the push of the logarithmic spiral curved scraper.

  

The scum of the surface of the scraper is concentrated to the area between the scum scraper and the scum baffle. When the working bridge is effectively passed through the scum discharge cylinder floating on the pool surface during operation, the scum is discharged. The cylinder is pressed under the liquid surface, and the scum is discharged out of the pool through the discharge cylinder. The scraper is mainly used in urban sewage treatment plants, waterworks and circular sedimentation tanks with large diameter in industrial wastewater treatment, and the sludge settled at the bottom of the tank and the scum of the pool surface are removed.

  

The driving device of the scraper will drive the scraper to rotate around the center of the sedimentation tank to a certain extent. During the operation, the raw water will effectively pass through the sedimentation tank, and the supernatant will be discharged from the overflow weir and precipitated. The sludge at the bottom of the tank, under the impetus of the logarithmic spiral curved scraper, slowly flows along the bottom of the tank to the central mud collecting tank and is discharged through the draining pipe. At the same time, the scum of the pool surface is concentrated to the area between the scum scraper and the scum baffle. When the working bridge passes through the scum discharge cylinder floating on the pool surface, the scum discharge cylinder is pressed under the liquid surface, and the scum passes. The discharge cylinder is discharged outside the pool.http://www.shallowairfloatation.com/
