What substances can be separated using decantation?
Oil and water, Dirt and water, Kerosene and water, Milk and cream, Blood and plasma are the five mixtures that can be separated through decantation method. The process of separating liquid from solid mixture and other immiscible liquid is known as decantation.

• All parts directly touching material are made of stainless steel
• Continuous and automatic operation minimizes labor costs
• Two motor drive with adjustable bowl and screw speed via VFD
• Continuous spiral discharging with PLC control and touch screen operation
• Scroll conveyor coated with wearable alloy or welded with alloy plate (according to material characteristics and customer demand)
• Safety protections include: rotation rate detection, vibration protection, motor overload and overheat protection, scroll protection when zero differential speed occurs

The bowl and screw make high-speed rotation with a certain differential speed between them. Materials enter the bowl from the feed tube. Under centrifugal force, the liquid of higher specific weight accumulates on the inner walls of the bowl and is discharged through the centripetal pump or overflow plate. Lighter liquids form an inner liquid ring, stick to the surfaces of heavy liquids, and discharge from the overflow channel. The spiral material pusher continuously pushes solids to the bowl's taper end where they discharge from the residue outlet after drying.

The LW series 2-phase sedimentation decanter centrifuge is a horizontal, continuously working and continuously spiral discharging sedimentation centrifuge, ideal for sewage sludge dewatering and thickening.
