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
