How it work ZW 700B uf membrane?
Table of Contents
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:
- Filtration Phase:
0.1-0.3 MPa feed pressure | Crossflow filtration | Contaminant retention - Forward Flush:
0.35 MPa pressure | 30-second duration | Particulate purging - Backwash Process:
0.25 MPa reverse pressure | Membrane wall cleaning | Fouling removal
4. Intelligent Control System
| Parameter | Specification |
|---|---|
| Filtration Cycles | 30-120 minutes (adjustable) |
| Flushing Parameters | Pressure/duration/frequency optimization |
| System Monitoring | Real-time TMP (<0.05 MPa) | Flux rate (80-120 LMH) |
