Dredging Slurry Separation System Working Process
The dredged slurry enters the Slurry separation system directly from the dredge.
In the first phase the slurry passes over scalping shale shakers to remove debris and larger particles. The debris can include: grass, roots, leaves, cans, plastic, rags and bottles. Solids Size≥0.41mm will be removed from the fluids.
The slurry with solids size≤0.41mm, with the above debris removed drops into an isolated section of the tank where it is picked up by a centrifugal pump.
This pump moves the slurry to the second phase, which is the De-sanding phase.
Here the slurry is pumped through the de-sanding Hydro-cyclones, which removes the solids above the 75 micron size.
The overflow from these hydro-cyclones drops into a second isolated tank section, while the underflow is deposited onto vibrating screens for drying of the solids.
The slurry, which now has solids removed above 75 microns is picked up from this tank section by a second centrifugal pump and pumped through a bank of de-silting hydro-cyclones to remove the solids passed by the de-sanding hydro-cyclones. This phase removes solids down to the 25 micron size. Again the overflow from the de-silting hydrocyclones drops into the third tank section, while the under flow is deposited onto vibrating screens for drying.
The now “cleaned” fluid is picked up by the third centrifugal pump to be transported to a point designated by the client.
If want to separate fine particle, the next stage can use centrifuge.
