4 Phase Mechanical Separation

A 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.

The Key Highlights Keep Your Cost as Low as Possible

Strong Screens

The scalping coarse screen is made of stainless steel bars, strone enough to bear big particles, durable design to make sure it last longer time.
The fine screen and dewatering screens are composite frame, which triple the screen life time than normal steel frame.

Tungsten Carbide Tiles & Scokets

The screw of decanter centrifuge been fully covered by tunsten carbide tiles, the upgraded design tiles are more resistance also ensure a longer life time, the slurry ports and solids discharge ports are also well protected by the tungsten carbide sockets.
