Separation in the i-Dec decanter centrifuge is achieved within a horizontal cylindrical bowl equipped with a screw conveyor. This bowl rotates, creating centrifugal force that causes solids to sediment against the bowl's wall. The conveyor, rotating slightly slower than the bowl, moves the solids towards the conical end, while a patented Liquid-Lock design accelerates light particles for optimal separation. This process takes place throughout the cylindrical bowl, requiring relatively low G-force for effective capacity and cake dryness. The i-Dec, manufactured by Alfa Laval, offers a cost-effective solution for continuous sludge dewatering and thickening in various applications, including municipal and industrial wastewater treatment, as well as potable water treatment. It is engineered for reliability and simple operation, featuring low power consumption, a small footprint, and quiet operation. The i-Dec's design incorporates patented solutions, such as FeedProtect for gentle product acceleration and reduced abrasion, DeepPond for improved separation performance and energy efficiency, and PowerTubes for energy recovery and minimized power consumption.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
