Food Waste Disposal

Watercourse dredging and dewatering separation system is used for river dredging sludge sewage separation device, by the vibrating screen, desander, desilter, and Decanter centrifuge. Depending on different situation, you can choose 3-6 level separation system.

Its system according to the structure can be divided into skid-mounted and vehicle-based, according to the actual situation of the scene to choose the appropriate type of structure. Processing capacity 120m³ / h-2000m ³ / h.


Separation of Six Purification Granularity

Shale Shaker-Desander(10”)-Desilter(4”)-Desilter(2”)-Decanter Centrifuge (mechanical separation)- Decanter Centrifuge (flocculation separation.Based on different circumstances, A 3-6 level separation system is available.

Dehydration Separation System Workflow 

a) The sludge enters the sludge separation system from the dredger or transition pool.

b) In the first stage, the shredder is passed through a shaker to remove debris and bulk solids. Larger size solids will be removed (this fraction is determined by the choice of mesh size).

c) Smaller than the size of the first mesh screen mesh mesh with the mud into the tank of a separate warehouse, waiting for centrifugal pump extraction.

d) The centrifugal pump delivers the slurry to the second stage, the de-sanding stage.

e) The slurry is conveyed to a desander cyclone where more than 70 microns of solid particles are removed.

f) The overflowing slurry from the de-sanding cyclone enters the second individual bin, and the material discharged through the cyclone discharge port
The material was dried on a sifter.

g) The second chamber was pumped through a second pump to remove more than 70 microns of mud into the 4-inch desilting cyclone unit to remove the solids through the desander cyclone. This stage will remove the 15-20 micron size of the solid particles. The overflowing liquid from the mud cyclone enters the third tank, and the material discharged from the slag discharge port of the cyclone falls onto the bottom flow screen and is dried.

h) The two-inch desilting cyclone separates 10 microns of solid-phase particles according to a similar principle.

i)  2-5 micron solid particles can be separated by decanter centrifuge mechanical separation

j) Through the chemical flocculation dosing system with the grid-run centrifuge can be sludge dredged sewage particles are separated into clean water can be discharged


The silt can be directly loaded and transported by the river dredging and dewatering separation system to reduce the transportation of sludge and reduce the transportation cost of silt. The user can select a certain stage of processing equipment according to different working conditions, and deal with the number of stages to meet the needs of specific conditions.


Economic Benefits 

Watercourse Dredging and Dewatering Separation System can treat river silt below 80% water content and make the sludge volume greatly reduced, so that it can use ordinary muck cars to remove the sludge after treatment, thus greatly reducing the cost of transportation. For the general project dredging project, so the construction side every day in the clear freight costs can save at least tens of thousands of dollars.
