Oil sludge, a mixture of oil, water, and solids, is not only difficult to handle but also poses a serious threat to the environment. The GNOST-05C oil sludge treatment system, with its efficient and environmentally friendly design, provides a novel solution for sludge treatment globally.

System Composition
The GNOST-05C oil sludge treatment system consists of four main modules:

Pre-mixing Tank Module: As the first step in the treatment process, the pre-mixing tank thoroughly mixes oil sludge with special chemicals, laying a solid foundation for subsequent separation.
Chemical Dosing Module: Based on the specific characteristics of the oil sludge, chemicals are added precisely to optimize the separation efficiency.
Three-phase Decanter Centrifuge Module: Utilizing powerful centrifugal force, this module achieves three-phase separation of solids and liquids in oil sludge.
Three-phase Disc Separation Machine Module: Building on the separation by the decanter centrifuge, this module further separates liquids of different densities, ensuring a thorough separation effect.

The Significance of Oil Sludge Treatment
Effective treatment of oil sludge is not only about the recycling of resources but also about environmental protection. By adopting the GNOST-05C oil sludge treatment, we can:

Recycle Oil and Water: The separated oil can be sold to refineries, and the water can be recycled for thermal washing, achieving the reuse of resources.
Low-cost Handling of Solids: The separated solids have an oil content reduced to below 2%, which can be treated through thermal desorption or biodegradation, achieving harmless disposal.
Protect the Environment: Reduce the pollution of oil sludge to the environment and promote sustainable development.

Sources of Oil Sludge
Oil sludge mainly comes from the following sources:

Waste oil sludge generated during the cleaning of crude oil tanks.
Waste oil sludge generated by refineries.
Waste oil sludge generated during drilling operations.
These sources of oil sludge all require effective treatment systems to reduce their impact on the environment.

Processing Capacity of GNOST-05C
The processing capacity of GNOST-05C is 5 cubic meters per hour, which can meet the needs of large-scale oil sludge treatment and is suitable for oil sludge treatment projects of different scales.

Synergy of Three-phase Decanter Centrifuge and Three-phase Disc Separation Machine
The combined use of the three-phase decanter centrifuge and the three-phase disc separation machine significantly enhances the treatment effect of the materials. The separation factor of the decanter centrifuge is about 3000G, while the separation factor of the disc separation machine can reach 12000G. This allows the disc separation machine to more thoroughly separate liquids of different densities. The liquid phase discharged by the disc separation machine is clearer, while the decanter centrifuge can effectively handle materials with higher solid content. In practical applications, materials usually undergo preliminary separation through the decanter centrifuge before entering the disc separation machine for in-depth processing to achieve the best separation effect.

With the successful sale of two GNOST-05C oil sludge treatment systems to overseas customers, GN has taken a solid step in the international market and further consolidated its leading position in the field of global environmental protection technology. The GNOST-05C oil sludge treatment system will become the preferred solution for global oil sludge treatment, contributing to the sustainable development of the environment.

GN Solids Control successful provide two sets of drilling mud dewatering decanter centrifuge systems to European client.

Each system is meticulously engineered with a GNLW364FT decanter centrifuge, a chemical dosing system, and a mud feed screw pump, all housed within standard containers for enhanced transportation efficiency and ease of installation. This innovative packaging approach significantly boosts the maintainability and protection of the equipment, ensuring a long service life and minimal downtime.

The T-series dehydration/concentration decanter centrifuges, chosen by the European client, are renowned for their robust separation capabilities and versatility. With a drum diameter of 14 inches, a length of 59.5 inches, a maximum speed of 3964 RPM, and a separation factor of up to 3200G, these decanter centrifuges are ideally suited for materials with large particles, significant solid-liquid density differences, low viscosity, and high concentration. They excel in applications requiring high treatment capacity and dryness, such as drilling mud.

The decanter centrifuges showcase exceptional performance in the treatment of drilling mud and challenging materials like fine particle-containing wastewater. By using flocculating agents to agglomerate particles, the T-series decanter centrifuges facilitate efficient dehydration, enhancing mud treatment efficiency and reducing the complexity and cost of subsequent processes.

Beyond drilling mud, GN Solids Control‘s T-series decanter centrifuges are widely applicable in various industries. They are employed in the separation and dehydration of environmental sewage, oily sludge, cutting fluids, sand washing water, ore washing water, and more.
