Description
Desander
Desander is desanding equipment for diaphragm wall construction.
Using the bentonite slurry to protect the bored trench or hole.
Eliminating the remains (gravel, sand, mud) from the fusion (bentonite and bentonite slurry are mixed) by centrifugal separation method of the desander's a various cyclone and mesh / vibration of the screen.
Excellent effectiveness is available when reusing the bentonite slurry.
Decanter

Slurry, contaminated with soil particles, is pumped into the hub of a rotating conveyor screw and passes into the rotating bowl sur-rounding the conveyor through ports in the conveyor hub, where the solids are separated out from the fluid by the centrifugal forces and deposited on the
bowl wall.
Due to a slight difference in the speed of rotation of the conveyor screw and the bowl, the conveyor screw continuously conveys the solids along the bowl wall to the solids discharge port, whilst the clarified liquid is continuously discharged in the opposite direction.

Applications
For slurry treatment in ;
- Foundation Construction.
(Diaphragm-Wall Construction, Reverse Circulation Drilling, Tunneling, etc.)
- Environmental Application.
(Cleaning System for Oil and Gas Industries, Sludge thickening and dewatering, Waste Treatment, etc.)
- Food and Chemical Industries.
According to respective requirement by environmental treatment plant,
Regeneration of slurries/Treatment of waste slurries

Soils of particle size <10μm (fine silts and clays) can't be separated out from the bentonite slurry by mechanical methods due to their very similar particle structure. Separation of such slurries into clear water and solid is achieved with the use of chemical additives which cause the fine soil particles to flocculate into larger flocculent masses (Polymers) which are separated out form the water as solid by secondary centrifuge. The regeneration rate and throughput capacity of the decanter centrifuge depend on ; - Speed of the conveyor screw and bowl of 1600 to 2000rpm.
