Hydrovac Slurry Separation System

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.     hydrovac slurry system 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.

Fully Hydraulic Drive Decanter Centrifuges for Middle East

GN Solids Control just shipped 4 packages of fully hydraulic drive decanter centrifuges to Middle East. As one the world famous decanter centrifuge manufactures, GN Solids Control has been manufacturing different sizes of decanter centrifuges for many years.

Now GN Solids Control is able to provide electrical driven and hydraulic driven decanter centrifuges, among them GN 14 inch and GN 18 inch bowl decanter centrifuges are largely equipment with hydraulic driven unit.

Due to the oil price going down and the double effect of COVID-19, the global oil and gas industry is very slow this year. But GN Solids Control succeeded to provide more solids control and waste management systems when customers try to find the most cost-effective equipment. Until now, GN Solids Control has been provided solids control equipment as well as drilling waste management systems to over 70 countries and regions. Word of mouth highly reputation bring more and more orders to GN Solids Control. GN Solids Control has provided hundreds of in Middle East. Usually, orders from Middle East are large orders with strict and high technical demands. With these years fast development, GN Solids Control is always able to provide the decanter centrifuges beyond customers’ expectation as GN wants to take the extra step.

The hydraulic bowl and scroll drive system drives both the conveyor and bowl of a decanter centrifuge from hydraulic pump unit by two hydraulic oil circuits.

The advantage of the full hydraulic drive centrifuge is for use in high temperature ambient for heavy mud with flexible bowl and differential speed. The compact one skid design makes it easier for rig up.
