The features that make the difference
Everything you need to meet your challenges today – and tomorrow
With more than 60 years of experience in solid-liquid separation, Alfa Laval knows what it takes to deliver high-performance solutions for the wastewater industry. Packed with features unique to Alfa Laval, our decanter centrifuges provide improved efficiency, reliability and serviceability with each advancement.
FeedProtect
Zona de alimentación con protección contra el desgaste sustituible
El exclusivo diseño de la zona de alimentación FeedProtect garantiza una aceleración suave del producto y una turbulencia mínima, lo que se traduce en un bajo nivel de abrasión y en un reducido consumo energético. El diseño FeedProtect está equipado con camisas de protección contra el desgaste sustituibles, lo que asegura una elevada disponibilidad operativa de su centrífuga decantadora.
DeepPond
High separation performance and energy efficiency
Increasing the pond depth inside the bowl creates a larger volume, leading to longer retention time and improved separation performance. The DeepPond design delivers high solids dryness and clean centrate from your decanter centrifuge, even at high flow rates.
PowerTubes
Liquid outlet with pond depth regulation and energy recovery
PowerTubes adjustable outlets are designed to release the liquid tangential to the rotating direction, supporting the bowl rotation and thereby recovering energy, and minimizing power consumption.
FlightProtect
Protection against wear on conveyor spirals
FlightProtect is a wear-resistant coating specifically designed for conveyor flights that preserves the integrity of each flight and extends its service life.
LiquidLock
Floating solids accelerator
A special device that accelerates floating solids from the surface into the solids layer. This results in liquids leaving the decanter centrifuge being of better quality.
How does a sludge dewatering centrifuge work?
Separation takes place in a horizontal cylindrical bowl equipped with a screw conveyor. The feed enters the bowl through a stationary inlet tube and is accelerated smoothly by an inlet distributor. The centrifugal force that results from the rotation then causes sedimentation of the solids on the wall of the bowl.
The conveyor rotates in the same direction as the bowl, but slightly slower, thus moving the solids towards the conical end of the bowl. A special patented Liquid-Lock conveyor design accelerates light particles before discharge for optimum separation. This also contributes to the small footprint of the unit.
Separation takes place throughout the entire length of the cylindrical part of the bowl. Relatively low G-force is needed for the i-Dec decanter to deliver good performance in terms of capacity and cake dryness. This contributes to low power consumption.
The clarified liquid leaves the bowl by flowing out of the casing viaspecial patented energy-saving PowerTubes that enable the effluent to discharge at lower speeds. The cake leaves the bowl into the casing through the solids discharge openings.
