GN design and manufacture waste management system for hydrovac slurry treatment and directional drill slurry. The solution is to use liquid and solids separation equipment to treat soil or soup or slurry generated from the hydrovac or HDD project and produce reusable material for construction and discharge clean water.

Normally, the slurry is contaminant-free comes from physical utility location in public right of ways, and directional drillingfor placement of underground pipes or utilities or other private property construction.

GN Hydrovac System Features

1) Complete Package design for Turnkey Solutions

2) Many years field proven experience

3) 4 Phase Separation System for better result

4) Modularized system for fast installation and flexible movement.

4 Phase Mechanical SeparationA standard hydrovac slurry separation system generally includes, scalping shaker, fine screening, desilter, then decanter centrifuge. If needed, desander cones can be added in between shaker and desilter, then it would be 5 phase.

Depends on site arrangements, what we have so far, is the vacuum truck dive backwards to a higher stand, dump thru a big hopper, which collectively leads everything to the scalping shaker, which separate most of the big solids out, the fluid then been transfered to a shale shaker which equipped finer shaker screens, to separate the finer particles out. Same as last step, the pump feed it to the desitler cyclones, thur the cylone fluids been pumped to the decanter centrifuge, the solids dewatered by the screens underneath.

The decanter centrifuge is final stage, considering the high solids content, this is actuall the most important step, normally also have some polymer ready for dosing the floating particles. After this, then all the solids stackable, water is reuseable.

Today we would like to give GN customers a short introduction of GN Cuttings Transfer Pump. As we all know, GN Solids Control is specialized in solids and liquid separation, many materials like high density, large viscosity, big solids content drill cuttings are hard to move when use tradition transfer pump. GN made cuttings transfer pump is especially designed to move the drill cuttings effectively. 

2020.07.05 GN Cuttings Transfer Pump 1


It’s usually seen that screw conveyors working in drilling rig site to collect the drilling cuttings discharged from shale shaker, mud cleaner, decanter centrifuge and cuttings dryer etc collected by screw conveyors first, and move to oil sludge treating plant for further treating. While screw conveyor is not suitable to use when there is too much water inside, also every time to assemble and disassemble the screw conveyor cost a lot time, let alone must take the tile angle into consideration. 
GN Cuttings Transfer Pump is using a hydraulic cylinder and the most popular S type distribution valve. Drill cuttings are moved by back and forward movement of the hydraulic cylinder and S type valve distribution. It can move high solids content drilling cuttings by flexible hoses to targeted treating equipment.
