Sludge Dewatering

Sludge dewatering is one of the most critical stages in wastewater treatment plants, as the high water content of sludge can make transportation, storage, and disposal costs unsustainable. Polat Makina decanter centrifuges operate on the principle of high centrifugal force (G-force) to separate solid and liquid phases, reducing sludge volume by 80–90%. This process converts sludge into a dewatered cake, preparing it for subsequent treatment processes such as incineration or composting. The enclosed system design minimizes odour emissions and environmental pollution, while automatic washing programmes eliminate the need for manual intervention, ensuring hygienic, environmentally responsible, and operationally safe performance.

Our Polat Makina decanter centrifuges are designed for continuous 24/7 operation and feature a fully automated, sensor-based control system that adjusts performance in real time to accommodate changing sludge characteristics. This technological adaptability reduces operating costs by minimizing polymer consumption, while tungsten carbide-coated wear parts extend equipment service life and increase maintenance intervals. The high clarity of the centrate (separated liquid phase) minimizes the pollutant load returned to the treatment plant, helping maintain overall system efficiency. Thanks to their compact design, our solutions deliver high capacity even in space-constrained facilities, enabling industrial plants to achieve environmental responsibility and high operational profitability simultaneously.
