At GN Separation, we specialize in providing innovative solutions for industrial separation needs. With over 10 years of experience, we have earned a strong reputation for delivering high-performance equipment. One of our standout products is the GN 3 Phase Decanter Centrifuge, designed for efficient solid-liquid-liquid separation. Recently, we have successfully shipped this cutting-edge technology to a client in South America, offering them a reliable solution for their oily sludge treatment process.

Three-Phase Separation Solution for Oily Sludge Treatment

Our GN 3 Phase Decanter Centrifuge is the perfect solution for industries that require the separation of oil, water, and solids. It excels in separating these three phases, ensuring a clean and efficient output, whether it’s for oil recovery, wastewater treatment, or other industrial applications.

This 3 Phase Decanter Centrifuge operates based on the principle of sedimentation, where the solid particles and two immiscible liquid phases with different densities are separated under high centrifugal force. When the mixture enters the high-speed rotating drum, the material is subjected to centrifugal force, causing the heaviest particles (solids) to settle first, followed by the heavier liquid phase (water), and finally the lighter liquid phase (oil).

The machine’s unique design includes a driving system, decanter bowl, screw conveyor, cover box, skid, and VFD control panel, allowing it to operate continuously for 24 hours, ensuring seamless and efficient performance. The GN 3 Phase Decanter Centrifuge can handle feed materials with less than 10% solids and particle sizes of less than 2mm, making it suitable for a variety of industrial applications, including oil recovery from oily sludge.

Modular Design for Complete Oil Sludge Treatment

Our solution for oily sludge treatment is built around three key modules:

1. Mud Conveying Module
   The mud conveying system ensures a smooth flow of materials to the decanter centrifuge. The equipment is designed to transport sludge efficiently, preparing it for the separation process. This system helps minimize material loss and optimizes overall processing time.

2. Tank Cleaning and Sludge Settling Module (Slant Plate Clarifier)
   GN Separation’s Slant Plate Clarifiers play a key role in washing and settling oil tank sludge. This module helps separate the bulk of solids and water before the material is sent to the decanter centrifuge. By utilizing inclined plates, this system accelerates the settling process, improving the efficiency of the subsequent separation stages.

3. Three-Phase Decanter Centrifuge Module
   The GN 3 Phase Decanter Centrifuge is the heart of the separation process. Its high-performance design ensures efficient separation of oil, water, and solids. This technology is crucial for industries that need to recover oil from sludge while separating water and solids for proper disposal or treatment.
