Stable Continuous Filtration for Ammonium Sulfate Production
At the Hubei Langrun project site in China, Jiangsu Huada completed the stable-operation validation of an ammonium sulfate concentration and filtration system.
The process required reliable continuous solid-liquid separation under high-salinity and highly corrosive operating conditions. Consistent filter-cake moisture, stable throughput and mother-liquor recovery were key production targets.
Project Challenge
Ammonium sulfate production can place demanding requirements on filtration equipment. The system must handle corrosive process media while maintaining continuous operation and stable cake-discharge performance.
The primary separation requirements included:
- Stable operation under high-salinity and corrosive conditions
- Continuous high-throughput solid-liquid separation
- Consistent control of residual filter-cake moisture
- Improved mother-liquor purity
- Higher resource-recovery efficiency
- Reduced interruption during continuous production
Huada Equipment Solution
Jiangsu Huada supplied an LLWZ Series Horizontal Thickening Screen Worm Centrifuge for the ammonium sulfate concentration and filtration process.
The LLWZ series combines centrifugal sedimentation and centrifugal filtration in one continuous separation system. The material is first concentrated before entering the filtration section, helping reduce the filtration load and improve overall separation efficiency.
Selected Equipment
Equipment Series: Jiangsu Huada LLWZ Series
Equipment Type: Horizontal Thickening Screen Worm Centrifuge

Operating Results
Following commissioning and operational adjustment, the centrifuge completed stable-operation validation at the project site.
The system achieved:
- Stable high-throughput continuous operation
- Consistent solid-liquid separation performance
- Filter-cake moisture consistently controlled below 1%
- Improved mother-liquor quality
- Enhanced resource-recovery efficiency
- Reliable operation under demanding process conditions
The verified operating results demonstrate the suitability of the Huada LLWZ Series for continuous filtration processes involving ammonium sulfate and other crystalline materials under corrosive production conditions.
Why the LLWZ Series Was Selected
The LLWZ Series is particularly suitable for processes that require continuous concentration, filtration and solids discharge.
Its process advantages include:
