Benefits: * **Improved effluent quality:** The high solids capture of Merco centrifuges will significantly reduce the sludge content in the effluent, meeting environmental regulations and potentially improving water quality for reuse. * **Reduced disposal costs:** By efficiently removing solids, the plant can reduce the volume of sludge requiring disposal, leading to cost savings. * **Increased efficiency:** The high throughput of Merco centrifuges can handle larger volumes of wastewater, improving the overall efficiency of the treatment plant. 3. Additional Technology: Membrane Filtration Systems offer a further level of filtration and can be used to remove even smaller particles from the treated effluent, ensuring high water quality.
Introduction
Decanter centrifugation is a powerful solid-liquid separation technique that utilizes centrifugal force to separate mixtures based on density differences. This process is widely used in environmental and water treatment applications, particularly for dewatering sludge and separating suspended solids from liquids.
The Process
Decanter centrifuges consist of a rotating bowl with a helical screw conveyor inside. The mixture to be separated is fed into the bowl, where it is subjected to high centrifugal forces. This force pushes denser solids towards the outer wall of the bowl, forming a solid cake, while the lighter liquid phase is forced towards the center. The screw conveyor rotates at a slightly slower speed than the bowl, moving the solid cake towards the discharge end of the bowl, while simultaneously pushing the clarified liquid out through an outlet.
