Solutions
Equipment solutions built around paper mill process problems
Each solution starts from the production problem, then connects process data with the right equipment configuration.
Solution
White Liquor Filtration Solution
Filtration and washing equipment configuration for stable white liquor clarity and lime mud recovery.
Solves
Poor white liquor clarity, unstable lime mud washing and high mud moisture can reduce recausticizing stability and increase operating load in the chemical recovery area.
- White Liquor Disc Filter
- Precoat Lime Mud Disc Filter
- Continuous Causticizer
Solution
Green Liquor Clarification Solution
Clarification system for green liquor dregs separation before recausticizing.
Solves
High dregs carryover in green liquor can increase load on recausticizing equipment, affect lime mud quality and reduce downstream filtration stability.
- High-Efficiency Green Liquor Clarifier
- Lime Slaker with Grit Removal
- Continuous Causticizer
Solution
Lime Mud Washing & Dewatering Solution
Disc filtration and precoat filtration equipment for lime mud washing, alkali recovery and dewatering.
Solves
Insufficient lime mud washing or high moisture can waste alkali, complicate mud handling and affect chemical recovery operating economics.
- Precoat Lime Mud Disc Filter
- White Liquor Disc Filter
- Screw Conveyor
Solution
Recausticizing Process Equipment
Integrated equipment for green liquor clarification, lime slaking, causticizing and white liquor preparation.
Solves

- High-Efficiency Green Liquor Clarifier
- Lime Slaker with Grit Removal
- Continuous Causticizer
Solution
Pulp Washing & Thickening Solution
Pulp washing, thickening and filtrate extraction equipment for pulp mills and paper mill process lines.
Solves
Insufficient pulp washing or unstable consistency can increase chemical carryover, reduce downstream process stability and limit production upgrades.
- Flat Valve Vacuum Drum Washer
- Conical Valve Vacuum Drum Washer
- Twin Roll Press
Solution
Paper Mill Equipment Upgrade Solution
Equipment replacement and process-section upgrades for existing paper mills and chemical recovery plants.
Solves
