Last Week, GN shipped out two sets slurry dewatering system used in construction industry to a client from USA. The client ever ordered 2 sets same system from GN and they were satisfied with the performance, thus they gave repeated orders this year for total 4 sets. The shipped were the first 2 sets.Last Week, GN shipped out two sets slurry dewatering system used in construction industry to a client from USA.

Construction slurry is mainly coming from hadrovac excavation, piping job, no did drilling and even the flushing slurry in construction site. The composition of the slurry is consisting of sand, silt and water. The using of the dewatering system can separate out the solid particles in the slurry to make the water reusable. Washed solids can be sold for land fill or making of construction material to get more profit. 

The dewatering system is consisting of below modules
1. Slurry Collection Hopper – per client requirement, GN designed a large open top hopper with 3-side weir surrounded, 1 side is low weir for slurry feeding from the vacuum tanker vehicle. The hopper is designed with water spraying pipe system to assist the slurry drop to the hopper discharge port easily.

2. Coarse Screen Module – One unit coarse shaker is installed under the collection hopper for coarse solids separation. Coarse shaker in installed on collection tank into where the slurry will drop waiting for further treatment. The submersible pump installed on the tank is used to transfer the slurry to subsequent module.
3. Fine Screen Module – the slurry treated by the coarse shaker will be pumped to fine screen shaker for small size sand separation, the shaker deck is covered with rubber to prevent the slurry spraying out to contaminate the equipment.

4. De-dilting Module – de-silter is a machine used for finer solids separation from slurry. It has hydrocyclone unit and under flow drying shaker to remove finer solids and make the discharged solids dryer for easy conveying.
5. Decanter Module – the decanter centrifuge is working by centrifugal force to separate solid and liquid. Its rotating part runs at a high speed to produce high G force that can remove the ultrafine solids in the slurry to make the recovered water cleaner. 

GN construction slurry dewatering system adopts the concept of separating the solid from slurry step by step by using different separation equipment to ensure the classification performance and maximally protection on the equipment. More and more clients showed their interesting on the system and expected to have the opportunity to cooperate with GN.
