Product Details
High salt rejection membrane for urea is developed for industrial automotive urea purification applications where stable product quality and reliable separation performance are essential. Designed for DEF, AUS32, and AdBlue® manufacturing systems, the TF8040-UR membrane helps manufacturers maintain consistent purification performance while supporting efficient operation under continuous production conditions.
Large-scale automotive urea production often involves fluctuations in feed concentration, temperature, and system loading. These changing process conditions can affect membrane stability and increase maintenance requirements over time. TF8040-UR is engineered with an optimized feed channel structure that promotes balanced flow distribution across the membrane surface, helping reduce pressure loss and maintain stable operating conditions during long production cycles.
The membrane adopts an 8040 spiral-wound configuration for compatibility with common industrial membrane housings and pressure vessels. Its robust structure and broad chemical cleaning tolerance allow system designers and end users to integrate the element into different purification layouts according to process requirements.
Suitable applications include:
- DEF (Diesel Exhaust Fluid) production systems
- AUS32 manufacturing lines
- AdBlue® purification plants
- Automotive-grade urea processing
- Industrial urea separation systems
- OEM water treatment equipment projects

Typical Process Flow in Automotive Urea Production
In automotive-grade urea (DEF/AUS32) production, membrane performance plays a key role in ensuring product consistency and stable system operation. A typical process flow is as follows:
Raw Water
↓
Pretreatment Filtration
↓
Urea Dissolution / Solution Preparation
↓
Cartridge Filtration (Fine Filtration)
↓
TF8040-UR Membrane Purification Stage
↓
Final Concentration Adjustment / Polishing
↓
Finished DEF (AUS32) Product
Proper pretreatment design and stable operating control help reduce fouling load on the membrane, ensuring long-term stable performance and extended service life.
Why Membrane Selection Matters for DEF Production
Selecting the right membrane element directly affects system maintenance frequency, operating pressure, and overall product consistency.
Stable Flow Distribution
Uneven flow inside membrane channels may lead to localized fouling. TF8040-UR adopts an optimized feed spacer design to promote more uniform flow distribution across the membrane surface, supporting stable long-term operation.
Low Pressure Drop Design
Excessive pressure loss increases energy consumption and can affect system stability. The element is engineered with a low ΔP structure to maintain stable hydraulic conditions during continuous operation.
Improved Cleaning Compatibility
In industrial systems with long operating cycles, cleaning performance is critical. With a wide CIP pH range of 1–13, the membrane supports flexible cleaning strategies based on actual fouling conditions.
Suitable for Continuous Industrial Operation
High-rejection membranes used in urea purification systems must maintain stable performance under continuous production conditions. TF8040-UR is designed to provide consistent separation behavior and reliable operation, helping reduce downtime and support long production cycles.
