Bottom Sludge Scraper

Bottom Sludge Scraper           
How does it work           
The bottom sludge scraper specially designed for continuous transportation of sludge.              
The equipment have been used  with a success in a number of different types  of sedimentation system.           
The principle involved in the scraper is that of the forward and return movement            
to the hydro dynamically designed sections. When the sections move forward , the concave faces of the wedges            
transport the sludge with them in the direction of the sludge pit. During the return movement.           
The points of the wedges slide under the blanket of sludge , so that it flows over them.            
The speed of the return movement is faster than of the forward movement,            
to give continuous transportation of the sludge.           
The repeated movement of the sections have the effecte of thickening the sludge, thus increasing its total solid content            
while at the same time guiding it towards the sludge pit.           
           
Surface Sludge Scraper           
The Surface sludge scraper is designed for efficient removal of surface sludge with a minimum of transportation water.            
The scraper blade draw off the whole of the tank surface transporating the sludge to a scum pipe. The drive bar move            
forward and return.the systme of lever on the the slide change its direction of movement when it reached it end position.           
How does it work           
A system of levers on the slide changes its direction of movement            
when it reaches its end position. The sludge being passed from one blade           
 to the next on its way to the scum pipe, Each blade is angled upwards           
 90 degree during its return movement, to ensure that sludge            
dose not accompany it.           
           
Possibilities of use           
For rectangular sedimentation tanks of waste and  water treatment plants,            
Drinking water purification plants.            
Industrial process waste water treatment plants,            
Flotation tank           
           
Principal of Advantage           
 - Few moving parts           
 - Minimum of maintenance           
 - Continuous sludge transportation           
 - No interruption of the sedimentation process           
 - High operational reliability           
 - Easy to adapt for use in existing tanks           
 - Sludge thickening function           
 - Easy to adapt for use in existing tank
