Aldec G3

Slibontwateringscentrifuge - een reeks innovatieve parameters

De ongeëvenaarde decanteercentrifugetechnologie van Alfa Laval heeft de weg vrijgemaakt voor een reeks baanbrekende innovaties, allemaal gebaseerd op bewezen technologie die bekend staat om zijn betrouwbaarheid. Samen zorgen deze voor een unieke combinatie van betere prestaties en een lager energieverbruik, wat resulteert in lagere operationele kosten dan ooit tevoren.

De kleinere transporteurdiameter van de Aldec G3 slibontwateringscentrifuge creëert meer ruimte voor vloeistof in de vijver en maakt hogere komwanddrukken mogelijk, wat resulteert in een drogere cake of een verminderd polymeerverbruik.

Gepatenteerde Alfa Laval Power Plates verminderen effectief het energieverbruik van Aldec G3 decanteercentrifuges en leveren daarmee een aanzienlijke bijdrage aan kostenbesparing bij slibontwatering.

Elke Aldec G3 slibontwateringscentrifuge is standaard uitgerust met een PLUS-regelpakket, dat vooraf is geïnstalleerd en getest met de specifieke eenheid. De combinatie van PLUS-besturing met de Aldec G3 slibontwateringscentrifuge garandeert optimale prestaties en houdt installatie-, inbedrijfstellings-, bedrijfs- en onderhoudskosten tot een minimum beperkt.

The features that make the difference

With over 60 years of expertise in solid-liquid separation, Alfa Laval delivers cutting-edge solutions to tackle sludge dewatering challenges. Engineered with patented Alfa Laval innovations, the Aldec G3 sludge dewatering decanter sets new benchmarks in efficiency, reliability, and serviceability.

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.

SuperPond

Increased 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 SuperPond design features a deeper pond and smaller solids outlet diameter, resulting in high solids dryness and clean centrate at high flow rates, as well as low energy consumption.  

VecFlow™

Rotating feed zone 

Low turbulence in the decanter centrifuge bowl is essential for high separation performance and low power consumption. The VecFlow™ rotating feed zone gives you maximum performance with minimal turbulence.

FlightGuard

Ellenálló kopásvédelem a szállítócsigához

A FlightGuard kopásvédelem a dekanter centrifuga szállítócsigájára hegesztett lapokból áll, amelyek erős kopásállóságot és hosszabb üzemidőt biztosítanak erősen abrazív alkalmazásokban.

FeedProtect

Betáp zóna cserélhető kopásvédelemmel

Az egyedülállóan kialakított FeedProtect betáp zóna a termék kíméletes felgyorsítását és minimális turbulenciát biztosít, ami alacsony kopást és energiafogyasztást eredményez. A FeedProtect kialakítás cserélhető kopásvédelemmel rendelkezik, így biztosítva a dekanter centrifuga magas üzemidejét.

VecFlow™ Technology

Optimize your wastewater sludge dewatering and sludge thickening

VecFlow™ technology delivers outstanding performance in wastewater sludge thickening and dewatering. The unique VecFlow™ feed zone of Aldec G3 decanters minimizes turbulence and reduces power consumption by up to 30% compared to traditional decanter centrifuges.

Minimal turbulence for maximum performance 

Aldec G3 decanter centrifuges equipped with VecFlow™ technology for sludge thickening gives you maximum performance with minimal turbulence. Alfa Laval’s unique VecFlow™ sludge centrifuge feed zone reduces turbulence by more than 80% compared to traditional decanter centrifuges and cuts acceleration power by 40-50%.

Gentle acceleration

A traditional feed zone injects the sludge radially into the decanter bowl, continuously disturbing the internal flows and causing turbulence. A VecFlow™ feed zone, on the other hand, gives the feed a completely different flow path since it accelerates the sludge tangentially when entering the bowl of the decanter centrifuge.

Sludge centrifuges with better separation performance

Apart from reducing total power consumption in sludge thickening, the low turbulence also improves separation performance. The separation is more effective than in a traditional decanter centrifuges, with less break-up of flocs. Additionally, the efficient acceleration to full speed reduces wear on the conveyor.

Cut OPEX

Depending on your specific sludge-thickening requirements, you may wish to minimize polymer consumption, increase the dryness of the cake or boost capacity. The high separation performance in thickening and low power consumption leads to a low total cost of ownership and very short payback times. You often get a full return on your investment in less than one year.

At the forefront of sludge thickening technology

PowerTubes feature on sludge centrifuges has become the preferred choice for wastewater plants around the world

The PowerTubes liquid discharge recovers kinetic energy from the effluent. By directing the flow tangentially as it exits the decanter bowl, the decanter bowl is pushed in the direction of rotation, causing a significant reduction in energy consumption.

Proven sustainability improvements with Aldec G3 decanter centrifuges

Aldec G3 sludge centrifuge is an excellent tool for improving your plant’s environmental sustainability

The lower power consumption leads to reduced CO₂ emissions. The high dry solids content reduces transportation requirements and landfill volumes, alternatively fuel consumption in incineration ovens.
