Recently, GN Separation completed the manufacturing and testing of two GNLWS554 Three-Phase Decanter Centrifuges. These centrifuges have been sent to North Africa to recover oil from olive oil sludge, a byproduct of production.
How GN 3-phase Decanter Centrifuge Operate
GN 3 phase decanter centrifuge is mainly designed for Solid-liquid-liquid three-phase separation of materials.With our over 10 years of experience in the separation industry, it is the most advanced type machine for 3 phase separation. It is designed for 24 hours continuous and smooth operation throughout the day. It is mainly composed of driving system, decanter bowl, screw conveyor inside the bowl, cover box, skid and VFD control panel.
They are advanced machines used to separate mixtures into solids, light liquid (often oil), and heavy liquid (like water). The process starts by introducing the mixture into a rapidly rotating centrifuge bowl. The centrifugal force separates the components, pushing the heavier ones to the bowl’s wall and the lighter liquid to the center. A scroll propeller moves the settled solids to the discharge end, preventing re-mixing. Meanwhile, the light and heavy liquids are discharged separately from different outlets.
Application in Olive Oil Production and Sludge Treatment
Olive oil production creates large amounts of waste sludge with reusable oil. Traditional disposal methods are harmful to the environment and waste resources. The GNLWS554 centrifuges provide a sustainable solution by effectively separating the oil from the sludge, enabling its recovery for reuse in production or other applications.
Key Features of GNLWS554 Centrifuge
GN Separation’s GNLWS554 3-phase decanter centrifuges are designed robustly and are well-suited for challenging applications such as olive oil sludge treatment. Key features include duplex stainless steel for high corrosion resistance in handling oil-laden sludge, a centrifugal casting process for reducing vibrations and wear, and a centripetal pump design for fine-tuning the separation process and achieving consistent separation efficiency. These attributes make the centrifuges reliable and effective in environments where downtime is costly.
In summary, GN Separation’s 3-phase decanter centrifuges utilize advanced materials and innovative technologies to efficiently recover valuable oil from waste sludge. For further details, please feel free tocontact GN.
