Cross-flow Membrane Filtration System
The Cross-flow Membrane Filtration System is designed for continuous solid–liquid separation and liquid clarification applications requiring stable filtration flux and reduced membrane fouling.
The system operates under tangential flow conditions, where feed liquid flows parallel to the membrane surface. This cross-flow mechanism generates shear force that minimizes cake buildup and extends membrane service life.
Available with ceramic or polymer membrane modules depending on application requirements.

Key Features:
Key Feature 1 — Stable Filtration Flux
Tangential flow reduces surface deposition and maintains consistent permeate flow over extended operating periods.
Key Feature 2 — Reduced Fouling & Longer Membrane Life
Continuous cross-flow shear limits particle accumulation and enhances operational stability.
Key Feature 3 — Modular System Design
Scalable membrane modules allow flexible capacity expansion.
Key Feature 4 — Suitable for Continuous Operation
Designed for steady-state industrial processing.
Key Feature 5 — Automated CIP Cleaning
Integrated cleaning-in-place system restores membrane permeability without disassembly.
Typical Design Range:
Membrane Type: Ceramic / Polymer (MF / UF optional)
Pore Size: 0.05 – 1.0 μm (depending on membrane selection)
Operating Pressure: 0.2 – 1.0 MPa
Operating Temperature: up to 150°C (ceramic)
Cleaning Method: CIP compatible
Configuration: Single module or multi-module skid
Typical industries and products:
• Catalyst recovery
• Fine chemical clarification
• Fermentation broth separation
• Wastewater reuse
• Beverage clarification
• Pharmaceutical intermediate purification
Working Principle:
The feed slurry is circulated through membrane modules at controlled pressure and cross-flow velocity.
Under transmembrane pressure (TMP):
Permeate passes through the membrane wall.
Retentate continues flowing tangentially, reducing particle deposition.
Key operating variables:
Transmembrane Pressure (TMP)
Cross-flow Velocity
Temperature
Membrane Pore Size
The balance of these parameters determines separation efficiency and flux rate.
