Recently, GN Solids Control completed the production and commissioning of a 5m3/h oily sludge treatment system and prepared to send it to Guangdong for the oil sludge reduction treatment project.


This oil sludge treatment system consists of the following modules:

1) Heating premixed and tempered tank

2) Shale shaker module

3) Horizontal screw centrifugal separation module

4) Three-phase disc oil-water separation module (slope plate separation separation, oil-water separator, disc centrifuge, etc.)

5) Dosing system processing module


The solid phase oil content after treatment by GN Solids Control sludge system can be controlled within 3%, the total water solid content in the recovered oil can be controlled within 3%, and the oil content in the recovered water is within 3%, which can greatly reduce the solid phase material. The oil content rate reduces the total amount of materials to be treated, and also provides the maximum reduction guarantee for the later biodegradation, thermal desorption and other processes, and improves the treatment efficiency of oily sludge.

In order to better meet the customer’s requirements and provide the most effective sludge disposal solutions, we need our customers to answer the following questions:

Source and type of waste (drilling, refining, or other?)

Waste composition, oil content, water content, solid content?

What is the maximum particle size of the solid? Is there a solid particle size distribution?

Solid phase requirements, liquid phase requirements, use of processed materials?

The oil sludge treatment system is one of the separation solutions promoted at home and abroad in recent years. It is mainly used to treat sludge from oil field drilling, oily wastewater from refineries and sludge from oil storage tank bottom sludge.

GN Solids Control currently has three standard models of sludge handling systems with processing capacities of 1-2, 5-10 and 15 cubic meters per hour. The picture below shows the GNOST-05A produced by domestic customers in China.

The GN Solids Control sludge treatment system consists mainly of the following modules:

1. Premixing module – This module includes a mixing tank, a stirrer and a transfer pump. First, the sludge is diluted in the tank to make the sludge more fluid and easy for subsequent module processing. Water and chemicals are added to the storage tank, and as the temperature of the heating system increases, the emulsified oil separates from the solid to become a demulsification mixture.

2, coarse screening module – a high G shale shaker is the key equipment of the module. The coarse particles will be removed through the screen. In order to prevent sludge splashing, the vibrating screen is also equipped with an anti-splash device.

3. Three-phase separation module – This module is combined with a centrifuge assembly and a disc centrifuge assembly. The centrifuge is used to remove most of the solids in the sludge to reduce the solids content. The liquid phase will then be sent to a disc centrifuge for separation of fine oil, water and ultrafine solids.

4. Chemical Dosing Device – GN Solids Control provides a container chemical dosing device that distributes chemicals to each module in the system. The containerized design makes the module easy to transport.

GN Solids Control has extensive experience in the development of this type of sludge handling system. A large number of case studies have been available at home and abroad for reference. For more information on GN Solids Control sludge handling equipment, please feel free to contact us.

The drilling and drying system is a major component of the closed loop system for drilling fluid treatment. It recovers as much of the drilling fluid as possible by handling the cuttings with high humidity. This week, GN Solids Control completed the manufacture of two vertical drill chip dryer systems and will ship them to Xinjiang customers soon.

Oil-based drilling cuttings are mostly treated with vertical drying systems. The entire system consists mainly of a cuttings drying module and a fine particle removal module. Each module has a critical core device.

Cuttings drying module

The vertical cutting dryer is the key equipment for the drying module. Usually, the cuttings are fed into a cuttings drying device. Under the action of centrifugal force, the oil will be separated from the cuttings and passed through the sieve holes into the collection tank in the drying device. The dry screen has an opening size of 250, 350 and 500 microns and can be used for different sizes of cuttings drying. The GN Solids Control cuttings dryer is equipped with a flushing system and an air knife system for cleaning the mud collecting tank and the screen to avoid clogging.

Fine particle removal module

The high specific gravity mud purification centrifuge is the key equipment of this module. The liquid effluent from the dryer will be pumped to a high specific gravity mud purification centrifuge for further processing to remove fines from the drilling fluid. In order to ensure the performance of the centrifuge, GN Solids Control takes into account the high-speed operation, the protection of wearing parts and the use of materials in the manufacturing process. Long-term operation and less maintenance ensure the efficiency and economic benefits of the equipment.

In drill cutting systems, mud tanks are used to install equipment and collect and store drilling fluids. The chips entering the dryer from the drying device and the centrifuge can be conveyed by a screw conveyor device, which is a conveying device widely used for conveying solid phase materials.

The mud water separation system is an economical purification system that separates solids from the drilling mud. It is mainly used in the construction piling project to remove the coarse particles in the mud. The recovered mud is pumped back to the pile driver for reuse.

Recently, GN Solids Control has just completed the assembly and factory test of nearly 10 500gpm throughput piling water separation systems. The picture shown here is a photo of the batch of equipment waiting to be shipped.

Advantages of piling mud water separation system

1. A variety of purification processes are highly integrated – the piling mud-water separation system consists of a coarse particle separation process and a Desander/Desilter separation process. After the mud enters the piling mud water separation system, the coarse particles are first sieved out using a vibrating sieve. The liquid will be pumped to the Desander/Desilter unit for fine particle separation. The piling mud water separation system has a built-in pump system, a buffer tank, and an electronic control system. A variety of purification process designs enable the system to separate fine particles to meet user needs.


2. Compact design – The piling mud water separation system is a combined device for gradually separating large particles and fine particles. Considering the limitation of the working area, the piling mud-water separation system has a small footprint and is easy to move in the urban interior space. For large-capacity active mud storage, users can make additional tanks that are easily connected to the piling mud-water separation system.

In order to provide users with a better piling solution, GN Solids Control has also developed a sloping plate settling system that settles the liquid discharged from the Desander/Desilter unit to make the liquid clearer. Compared with the sedimentation centrifuge, the inclined plate settlement system is a solution with high flow rate and low cost. In the sloping plate settling system, fine particles will settle to the bottom and then pump out through the diaphragm pump.

More and more piling contractors are considering the use of two piling mud separation systems and then a sloping plate settling system to achieve a low cost, cost effective solution.

Recently, GN Solids Control completed an in-plant test run of an automated tank Cleaning system. Customers from South America watched the workflow and successfully accepted the automatic cleaning system. The system will be shipped later.

As a professional manufacturer of solid-liquid separation equipment, GN Solids Control covers a wide range of products for the solid-liquid separation industry. The automatic can washing system is actually used to separate the solids from the cleaning mud to achieve the effect of recycling the water.

How the GN Solids Control automatic clearing system works

The GN Solids Control automatic clearing system is designed for automatic tank cleaning. After receiving the solid slurry with high solid content, the solid and liquid in the sedimentation tank are separated, and the built-in chemical dosing system adds flocculant to the slurry to accelerate the collection and precipitation of fine particles. The separated water will overflow and then fall into the storage tank for reuse.

Part of the GN Solids Control automatic clearing system:

1. Mud Collection Pump – At the beginning of the system, the flushing mud is delivered to the settling tank using an electric vacuum pump. The pump is connected to a lever sensor in the settling tank and can be automatically fed and stopped.

2. Sloping plate clarification tank——The sedimentation tank is a sloping plate clarification tank. There are multiple sloping plates in the clarification tank, and the spacing between the two sloping plates is even. These panels have a 55 degree sloping floor so that solids can settle quickly along the slab to the bottom of the clarifier.

3. Chemical Dosing System – The automatic cleaning tank system is equipped with a chemical mixing tank and a dosing pump. A flocculant can be made here and pumped to a precipitator for fine particle collection and precipitation.
