i-DW
The range of Alfa Laval i-DW decanter centrifuges is ideal for continuous sludge dewatering and thickening from municipal and industrial wastewater treatment as well as from potable water treatment, when the main focus is reliability, cost-efficiency and simple operation with medium capacity and dry solids.
Fundamental performance in a cost-efficient way
- Small footprint
- Low power consumption
- Low cost of ownership
- Low noise emission
Fremskyndelse af bæredygtige løsninger
Forestil dig en mere bæredygtig verden. En verden, hvor der kræves mindre for at producere mere. En verden, hvor vi effektivt opfylder vores voksende energibehov og samtidig reducerer CO2-udledningen. Forestil dig en verden, hvor vi kan udnytte naturressourcer og samtidigt bevare dem. Hos Alfa Laval er denne verden ikke blot en forestilling. Vi skaber den i fællesskab med vores kunder og partnere.
How it works - working principle of this decanter centrifuge for sludge dewatering and thickening
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 Liquid Lock conveyor design (patent pending) accelerates light particles before discharge for optimum separation. It also facilitates the small footprint.
Separation takes place throughout the entire length of the cylindrical part of the bowl. Relatively low G-force is needed for the i-DW 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 via special patented energy saving Power Tubes that enable lower speed of discharged effluent. The cake leaves the bowl through the solids discharge openings into the casing.
