Sludge Separator · Separators & Purifiers
Reliability and ease of maintenance are key features of the Alfa Laval i-DW decanter centrifuges, designed for efficient sludge dewatering in municipal and industrial wastewater treatment. These decanters are ideal for applications requiring medium to high capacity and dry solids with a focus on cost-efficiency and simplicity. The i-DW series meets fundamental performance criteria in a cost-effective manner, offering high quality, robustness, and easy serviceability. Innovative design elements, such as a liquid lock design and fully enclosed process sections, contribute to a small footprint, low power consumption, and low noise emission. The decanters use a horizontal cylindrical bowl with a screw conveyor to separate solids from liquids, with the screw conveyor rotating at a slightly slower speed to move solids toward the conical end for optimal separation. The bowl and other parts in direct contact with process media are made of AISI 304 stainless steel, with an optional AISI 316 grade for enhanced corrosion resistance. The i-DW decanters are equipped with a basic core controller for full control and monitoring, ensuring efficient operation and minimizing maintenance costs.
