How it work ZW 700B uf membrane?

1. Core Membrane Technology Features

The ZW 700B employs an innovative seven-channel hollow fiber ultrafiltration (UF) membrane module that achieves precision separation through absolute physical barrier mechanisms. Its multi-lumen design demonstrates 200% enhanced mechanical strength compared to conventional single-bore fibers, effectively eliminating operational risks associated with fiber breakage and ensuring long-term system stability.

• Third-party verified performance:
  • Suspended solids (SS) rejection: >99.9%
  • Microbial removal efficiency: 6-log
  • Particulate organic compounds (POC) reduction: Optimized

2. System Configuration Flexibility

This pressurized UF system utilizes an inside-out crossflow filtration mode, supporting versatile installation configurations:

• Orientation Compatibility: Horizontal or vertical installation options
• Vessel Flexibility: Pressure vessel or vessel-free configurations
• Structural Solutions:
  • RMS (Rackless Membrane System) integration
  • Standard rack-mounted assembly

Modular design accommodates 5-500 m³/h treatment capacities.

3. Operational Mechanism & Maintenance Protocol

Three-Phase Operational Cycle:

1. Filtration Phase:
   0.1-0.3 MPa feed pressure | Crossflow filtration | Contaminant retention
2. Forward Flush:
   0.35 MPa pressure | 30-second duration | Particulate purging
3. Backwash Process:
   0.25 MPa reverse pressure | Membrane wall cleaning | Fouling removal

4. Intelligent Control System
