Purpose and process of dewatering of Screw press sludge dewatering Jan 21, 2019

Since the residual sludge of the biochemical sewage treatment tank and the coagulated chemical sludge have a high water content and are in the form of a paste, the sludge is easily squeezed out of the sieve with the conventional dewatering process, which makes the muddy water difficult to separate. Therefore, there is a problem that sludge dewatering efficiency is low. In order to solve this problem, it is recommended to use a Screw press sludge dewatering dewatering.

 

The purpose of the dewatering of the Screw press sludge dewatering is to separate the solid matter in the mixed fluid having a specific gravity larger than that of the liquid phase fluid from the liquid phase fluid. When the mixed liquid has a feed port and enters the high-speed rotating drum body cavity, the solid matter with a large specific gravity in the mixed liquid rapidly settles to the inner wall of the drum under the action of centrifugal force, and is discharged from the solid phase by the screw ejector. Exhaust the drum outside the body.

 

At the same time, the liquid phase with a smaller specific gravity forms an inner liquid ring under the action of centrifugal force, and is discharged through the liquid phase overflow port to the outside of the drum. The drum and the screw ejector simultaneously operate at high speed. Because there is a certain difference in rotation speed between the two, the solid matter deposited on the drum wall is continuously pushed by the screw ejector to the liquid outlet, and the whole separation process is performed. Continuously
