Dredging Slurry Separation Unit

2020-05-28

River dredging process system is generally adopts a cutter suction dredger to absorb the muddy water mixture at the bottom of river, and then transport it along the pipeline to a sludge drying treatment field. After machine sorts the garbage mixed in mud, the mud is passed into the concentration tank in the field, and the mud water separation is carried out through the mud treatment system. Finally, water reaches the standard discharge, and the wet sludge is sent to sludge dewatering equipment to dehydrate and becomes solidified mud cake for reusing.

Dredging Slurry Separation Unit mainly used for the separation of sludge from rivers. KOSUN Dredging Slurry Separation Unit is consist of shale shaker, desander, desilter or decanter centrifuge for 3 to 6 stage separation depending on the needs.

Dredging Slurry Separation Unit

KOSUN Dredging Slurry Separation Unit is consisting of 3 parts. The first one is the dredging boat and first stage separation pool for large size of the trash. The dredging boat is always moving on the surface of the lake or river, and the suction unit would go down deep to the bottom of the lake or river and then suck sludge then transfer to the ground by a hose which is always float on the water surface. On the ground, there will be a pool which is divided into several parts by different mesh size of wire screen. The sludge flow coming out from the hose will get into the pool; the large size of the trash in the sludge would be blocked by these several wire screens, while the slurry will flow away for next process.

The second part of the Dredging Slurry Separation Unit is the recycling system which is including several equipment that is used especially for the solids and liquid separation. The slurry will be fed into a scalping shaker, here the solids which is large than 1/8 inch would be separated out, and the slurry would then be pump transferred to the desander for much fine solids removing. After treated by the desander, almost all the solids with size of 50 microns would be removed out.

The third part of the Dredging Slurry Separation Unit is the ultra-fine solids removing equipment. Some contractors like to use the filter press as the final solids removing units, the solids separated are really dry and shaped like cake. While another option is to use the decanter centrifuge that could be used to remove the ultra-fine solids with size down to 2 microns. After treated by the filter press or the centrifuge, the water is already clean that could be flow back to the lake or river.
