Working principle of wastewater treatment Central drive rotating scraper :

Wastewater enter into clarifier through the central steady flow tube, the central drive sludge scraper bridge fitted with a central shaft with arms and scraper blades that rotate in clockwise direction and thus convey the debris (sludge, etc.) towards the middle of the reinforced concrete tank, from where sludge is discharged.

On request, the machine can be fitted with the suspended solid extraction mechanism, which thanks to the bridge rotation, conveys the foams (oily and light parts present on the water surface) to the scum trough fixed to the reinforced concrete tank wall. The clean water flows through the V-notched weirs and flows into a discharge channel.

ZXG series wastewater treatment Central drive rotating scraper  is equipped with torque protection device, will shut down automatically once torque exceed set value to prevent damages.

ZXG wastewater treatment Central drive rotating scraper  can be used in almost all kinds of circular tanks to scrape and discharge sludge, the main applications are:

• Primary sedimentation tank
• Secondary sedimentation tank
• Final sedimentation tank
• Sludge thickening tank
