If have to change the title a bit, it is 2 systems in operation, happy, then placed 4 more systems, now 2 system is ready, and 2 more will be ready soon. GN have done many projects on hydrovac slurry separation, some of the projects we only offer products, some we offer complete solution.
, or Non-Destructive Dig (NDD) is a bit different with other civil projects like HDD, Trenchless, or Pipe-Jacking etc. The process of Hydrovac Excavation is a non-destructive method using pressurized water (Hydro) and a vacuum system (Excavation) to dig. With this process, Wolverine Hydrovac makes a visual observation of existing buried underground utilities, pipes, or unknown infrastructures so that they may be avoided when digging in the ground.
Then the whole process is also different, well the basic idea is same, spearate the particles stage by stage, from bigger rocks, to sands to silts. to clay. Do remember to check the definition of these particles.
Anyway, typically here is the system:
Slurry Collection Hopper – this is a customized piece, for their application, if you have a better idea based on your site, and whatever circumentance, you have the better layout for you, then do not mind telling us.
Coarse Screen Shaker – 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.
Fine Screen Shaker
– 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.
Dsilter Unit, similar as all the drilling mud separation systems, after the shale shaker, it comes to cyclones, and then it goes to
Decanter centrifuge, during the operation, the client have helped us compare a lot in between USA decanters and GN decanters, and finally they chose to stay with GN for future projects.
