drilling waste management

An South American Waste Treatment Service company sent information to us, GN Solids Control,  and looked for the exact solution for the DAF Sludge Treatment.

DAF, the full name is Dissolved air flotation, which can be widely used in sewage treatment, in the fields of industrial, manufacturing, oil & gas drilling, and marine waste water treatment.

DAF systems inject micro bubbles into the waste steam which attach to the solids and float them to the surface where they are skimmed off. However one of the more common issues with a DAF system is the mess associated and disposal cost and with handling the skimmed off waste solids.

For treating with the huge amount of Waste Solids, GN company offers reasonable solution to remove the Solid (suitable for discharge), and recollect the water and oil separately–Decanter Centrifuge plus Disc Centrifuge.

GN decanter centrifuge proves to be an effective and well proven equipment solution for dewatering the typically wet, sloppy solids skimmed off many DAF processes and wastewater systems.

GN supplies 250 sets of Decanter Centrifuges every year, with 70% purchased by the International Market, such USA, Canada, Holland, Australia, UK, Kuwait, Russia. It is 2 phase separation, for Solid and Liquid Separation.

 

After the solids being separated, if the client would like to recollect the high purified

Oil, Clean Water and separate the Fine Solids, GN suggest Disc Centrifuge

The Capacity can be from 1 m3/h to 15 m3/h, Bowl Speed reaches more than 6000 RPM.

Attention, the Solids Content of the feed material shall be 3% maximum.

Welcome to contact us, GN Solids Control, if you have problems with treating the DAF sludge. Our professional Technical Department would offer the exact solution based on your detailed requirement.

Before there is a friend from India, we met each other in local exhibition, he said that he ran a Cow farm, with more than 50 cows. Every day the biggest problem for him is how to deal with the huge amount of excrement? He couldn’t find more space in his farm to bury these excrement? It is always  a big headache for him.

Then I suggested him, maybe he can consider about our product, Decanter Centrifuge, the hot sale separation from GN Solids Control.

This special and professional can easily separate the Solid and Water.

At first, he didn’ t believe it, then I show him an video, he was amazing and exciting.

We, Hebei GN Solids Control Co., Ltd, is a leading manufacturer based in China and USA, specialize in separation equipment, include industry decanter centrifuge, solids control equipment, waste management equipment, and shaker screens.GN was established in 2007,and GN is the first API certified solids control equipment manufacturer from China, and GN products have been exported to over 60 countries around the world.

 

 

 

It is always a big headache for dealing with the Mud from our activity.
GN provides a reliable solution—Decanter Centrifuge.

 

GN Decanter Centrifuge is designed for the drilling mud solids control and oilfield waste management. GN VFD drive decanter centrifuge with variable speed allows Drilling Contractor or Mud Service Company to do the barite recovery, fine/ultra-fine solids separation, dewatering centrifuge. GN has the decanter centrifuge from 9 inch bowl to 22 inch bowl available for different applications. GN decanter centrifuge bowl length and diameter ration is over 3, this gives the best result!

• Patent Design with the highest configuration and best material for long and reliable service.
• Bowl Cylindrical and Conical section made from Duplex Stainless Steel 2304 by centrifugal casting.
• Other Parts of the bowl assembly material: stainless steel SS304.
• Screw protection: Tungsten Carbide Tiles for longer life and easier replacement.
• Screw flow distribution port and bowl solids discharge port protected by tungsten carbide alloy.
• Easily adjustable liquid discharge weir height for flexible application.
• Bowl assembly supported by tighten belt for protection of bearing in moving.
• Pressurized EX Proof VFD control cabinet with PLC controlled.
• Genuine SKF bearing for longer and reliable operation.

This week GN shipped one set of containerized drilling cuttings treatment system and several units of shale shaker to Russia. This is not the first containerized drilling cuttings treatment system sold to Russia, because of the low temperature in Russia area, the client do not want to stop operation in the long winter, this customized design is to keep the drilling fluids warm and prevent it from get frozen.


The containerized drilling cuttings treatment system including one unit of vertical G dryer with fluids collection tank, one mud agitator installed on top of the collection tank. The centrifuge feeding pump transfer the mud from fluids collection tank to the decanter centrifuge to separate more solids from the fluids, the final discharged solids can be reused for the drilling rig or used to prepare for new drilling fluids. The solids discharged from the vertical G dryer is with OOC < 5% like powder, they will be transferred by the screw conveyor to the cuttings box outside the container. One unit of 4kw screw pump is used as flashing pump of the vertical G dryer. The whole drilling cuttings system treating capacity is 40m3/h for oil based drilling cuttings, the decanter centrifuge with VFD control panel can be used to separate the fine solids from the fluids, the separation cut point is 2~5 microns.


The client also ordered several units of GNZS594 shale shaker with 4 panel composite material frame shaker screens, the screen size is 585x1165mm, the total screen area is 2.73m2, the G force is high up to 7.5G.

As the development of energy industry and also the enhancing demand of environment protection, the oily sludge, or oily waste discharged from the energy industry are being restricted to be disposed directly. The regulations and standards are more and more rigid than before. Now all the players in this field are facing a problem: how to treat the oily sludge efficiently and safely?

GN Solids Control has provided a solution, which is proved to be suitable in both domestic China and abroad. The complete system is combined of several equipment, which serve different applications, including the functions for heating, pre-mixing, reduce the viscosity, separating out the solid particles, leveling the oil and water and finally separate out all of the 3 phases.

GN Oily Sludge Separation SYSTEM
GNOWS series Oil Water Separator is one of the important equipment in an oily sludge separation system. It is located after the GNIPC Inclined Plate Clarifier or a GNLW decanter centrifuge to hold and further treat the liquid phase from forehand equipment, to separate the oil from water.
The working principle is gravity stratification cause by the different density of water and oil. Inlet of this equipment is the waste liquid, while the outlets are 3: the clean oil outlet, the clean water outlet and the gas release ports. Inside the GNOWS oil water separator, there is a detachable coalesce, when the oily wasted water enters the oil water separator and meets the detachable coalesce, the oil and water could be separated. Then the oil enters the oil chamber while the water enters the water chamber. The tank is designed to hold the liquid for a while for a complete separation of the 2 kinds of liquid. Outside the tank, there is a visible level meter, for the operator to observe the inside condition in time.
For this equipment, GN has different models for different treating capacities, please see details in GN website.
