Decanter Centrifuge Product Introduction
The 450 Type Decanter Centrifuge for Wastewater Treatment is designed for efficient solid-liquid separation and sludge dewatering in municipal and industrial wastewater treatment processes. It effectively separates suspended solids from wastewater, reducing moisture content in sludge and improving downstream disposal or treatment efficiency.
By utilizing continuous centrifugal separation, this decanter centrifuge ensures stable operation, high processing capacity, and reliable separation performance. It is widely used in wastewater treatment plants, industrial effluent treatment systems, and sludge management applications where consistent dewatering performance is required.
Working Principle
The feed slurry enters the rotating bowl through the inlet pipe. Under high centrifugal force generated by high-speed rotation, solids are thrown outward against the bowl wall, while the clarified liquid moves towards the liquid discharge ports.
An internal scroll conveyor rotates at a slightly different speed from the bowl to transport the separated solids toward the conical end for discharge. The adjustable differential speed allows operators to fine-tune separation performance and cake discharge depending on material properties.This continuous process ensures efficient, high-throughput separation with minimal manual intervention.
