Product Introduction
Its core structure comprises a concentration section and a dewatering section. The spiral pushes the sludge, gradually compressing it. The filtrate is discharged through the gaps between the rings, ultimately forming a low-moisture sludge cake. The device operates stably, requiring no filter cloth or centrifugal device, making it suitable for continuous, automated operations.
Key Features and Advantages
The low-speed screw shaft (2-4 rpm) consumes only one-third of the power of traditional equipment, reducing sludge moisture content from 99% to below 80%, significantly reducing sludge volume.
The self-cleaning filter slot design eliminates the need for frequent flushing and saves up to 70% water.
The integrated electronic control system supports 24/7 unattended operation.
Simple operation requires only regular lubrication and component inspection, reducing maintenance costs by 50%.
The modular stainless steel construction means only the screw shaft and the running ring require replacement, resulting in a lifespan of over five years.
Main Applications
Dewatering activated sludge from sewage treatment plants to reduce transportation and landfill costs.
Treatment of high-difficulty wastewater from the chemical, pharmaceutical, food (including grease sludge), printing and dyeing industries.
Separation of viscous materials such as heavy metal-containing electroplating sludge, aquaculture wastewater, and restaurant waste.
