Product Description

Screw Press Sludge Dewatering Machine is suitable for sludge dewatering of large, medium and small sewage plants. The dewatering machine replaces the traditional filter cloth and plate frame sludge dewatering method, reduces the investment cost and improves the treatment efficiency. It is suitable for municipal sewage treatment project and sludge dewatering treatment in food processing, printing and dyeing, paper making, pharmaceutical, leather and other industries, especially for slaughtering, petrochemical oily sludge dewatering treatment.

Working Principle & Composition

The equipment is mainly composed of frame, screw shaft, moving ring, static ring, separation ring, filtrate collecting tank, flocculating mixer, drive reducer, electrical control box and so on.

  • 1. Sludge is transported to the flocculation reaction tank through the sludge pump.
  • 2. Sludge and flocculant (PAM) mixed in the flocculation tank through the blender for full mixing.
  • 3. The solid-liquid mixture enters the spiral cavity through pipe gravity flow.
  • 4. Reducer drives spiral axis rotation, concentrating sludge while moving it towards dehydration.
  • 5. Filtrate flows from gaps between rings; mud cake is discharged via the back pressure plate.
Main Features
  • Oily Sludge Treatment: Superior to traditional belt and plate frame dehydrators for oily sludge.
  • Non-clogging: Unique dynamic and static ring filter joint with self-cleaning function.
  • Compact Design: Space-saving, small footprint, and convenient installation.
  • Durable Construction: Made almost entirely of stainless steel for long service life.
  • Automatic Operation: Simple maintenance and automatic induction devices.
