Worldwide, the dewatering of river silt is a major obstacle to river dredging projects. The desilting system with shaker, desander, and desilter can remove sludge above 25 microns, but fine particles below 25 microns cannot be processed. This is where the centrifuge comes in. In the case of mechanical separation without adding polymers, centrifuges can separate fine particles of more than 5 microns. Through the dosing flocculation technology, the centrifuge and polymer can be used together to achieve zero emissions.
River desilting centrifuge
For the separation of small particles, two types of separation equipment are usually selected, one is a centrifuge, and the other is a filter press.
Compared with the filter press, the centrifuge has the following advantages:
The use of centrifuge chemicals is significantly reduced because of the centrifuge’s high separation factor, which efficiently separates fine particles
Maintenance is easier and requires less service
It can be widely used in the treatment of silt in different waterways
It separates cleaner water
Using centrifuges is easier to install and requires a smaller footprint
Centrifuges can be operated automatically and require less manpower
It can save water resources required for washing equipment
