Product Details
Automotive urea filtration membrane features an advanced 34-mil feed spacer design, enabling extremely low pressure drop, exceptional fouling resistance, and remarkably high permeate flux during the industrial-scale production of automotive-grade urea.
The TF8040-UR membrane element is widely utilized in automotive urea filtration systems, DEF production equipment, AdBlue manufacturing plants, and various industrial urea purification processes. In these application scenarios, the membrane element's operational stability-as well as its ability to recover performance after cleaning-are critical to overall operational efficiency. The optimized feed channel structure not only improves fluid distribution across the membrane surface but also effectively minimizes scaling and particulate accumulation, thereby ensuring that the membrane element maintains stable, high-efficiency performance even under continuous industrial operating conditions.

5.Why Choose Our TF8040-UR Urea Purification Membrane
(1)34-mil Wide Feed Spacer (Low Pressure Drop Design)
TF8040-UR features an advanced 34-mil wide feed spacer structure, which significantly improves the fluid dynamics within the membrane element. By optimizing hydraulic resistance, this element enables more stable, long-term operation within continuous DEF (Diesel Exhaust Fluid) production systems.
(2)Optimized Feed Flow Velocity Distribution
Uneven flow velocity distribution is one of the primary causes of premature fouling in automotive urea filtration systems. Our automotive urea filtration membrane employs an optimized flow channel design to ensure a more uniform distribution of the feed stream across the membrane surface. This effectively minimizes "dead zones" (stagnant areas with low flow velocity), localized fouling accumulation, and uneven pressure distribution between elements. Consequently, the rate of fouling formation is slowed, and overall system operational stability is significantly enhanced.
(3)High Permeate Flux for Industrial-Scale DEF Production
This membrane element delivers a high permeate flow rate of up to 11,500 GPD (44 m³/day), ensuring superior production efficiency per element. It maintains stable output under industrial-scale operating conditions and facilitates a more compact system footprint-a critical requirement for large-capacity production facilities. This makes it ideally suited for large-scale automotive urea production systems that demand continuous and stable output.
(4)Enhanced Fouling Resistance
Fouling represents one of the most critical operational challenges faced by urea-based membrane filtration systems.
Through optimized hydraulic and structural designs, the TF8040-UR membrane element demonstrates enhanced fouling resistance. This results in a slower rate of fouling layer formation, reduced risk of irreversible fouling, extended operating periods between cleaning cycles, and improved long-term system stability.
Ultimately, this helps minimize downtime and reduce overall operating costs for industrial-scale automotive urea production systems.
(5)Broad Chemical Cleaning Compatibility (pH 1–13)
This membrane element is fully compatible with a wide range of chemical cleaning agents spanning a pH range of 1 to 13. This allows users the flexibility to formulate customized CIP (Clean-in-Place) strategies tailored to the specific types of contaminants present. Its broad chemical resistance significantly enhances flux recovery and extends membrane service life under demanding industrial operating conditions.
(6)Stable Permeate Quality, Ensuring Compliance with DEF Standards
In automotive urea (AdBlue®) applications, product batch consistency is critical for downstream compliance and the operational reliability of the system.
The TF8040-UR automotive urea filtration membrane element maintains stable permeate performance over long-term operation, helping to ensure:
● Consistent quality of AdBlue® / DEF products
● Reduced fluctuations in conductivity and purity metrics
● Stable operational performance of downstream systems
