Overview
What is the Precoat Lime Mud Disc Filter?
The Precoat Lime Mud Disc Filter is used for lime mud washing and dewatering after recausticizing. It supports higher lime mud dryness, lower residual alkali and more stable downstream lime kiln or disposal conditions.
Benefits
Key benefits
Benefits are stated in practical process terms so buyers can compare equipment against mill operating needs.
Lime mud washing and dewatering in one process section
Precoat filtration for difficult mud characteristics
Designed for stable continuous operation
Helps reduce residual alkali in lime mud
Configurable filtration area and discharge system
Suitable for chemical recovery upgrades
Working principle
How the equipment works
A prepared precoat layer acts as the filtration medium. Vacuum draws liquor through the layer while lime mud solids are retained, washed, dewatered and discharged as the precoat surface is continuously refreshed.
Applications
Typical applications
Application scope can be refined according to process flow, material characteristics and production capacity.
- Lime mud washing
- Lime mud dewatering
- Recausticizing plants
- Chemical recovery sections
- Paper mill upgrade projects
