​​MBR Membrane Technology: Industry Knowledge Overview​

Core Product Features

Advanced Materials Engineering

• Polymeric Membranes: Made from PVDF, PES, or PVC with pore sizes of 0.1–0.4 μm for microfiltration/ultrafiltration; cost-effective (30% lower than ceramics) and chemically resistant (pH 1–13).

• Inorganic Ceramic Membranes: Alumina- or zirconia-based, suitable for extreme conditions (pH 0–14, 350°C); 5* longer service life but 2* higher cost.

• Module Design: Includes hollow fiber (80% structural market share), flat sheet (high fouling resistance), and tubular (handles high-solids wastewater) configurations.

Hybrid Biofiltration Process

• Replaces secondary clarifiers in activated sludge systems, achieving sludge concentrations of 8,000–12,000 mg/L (3* that of conventional systems), enhancing treatment efficiency.

• Achieves >99% removal of suspended solids, bacteria, and viruses; effluent turbidity <0.5 NTU, BOD <5 mg/L.

Smart Operation & Automation

• IoT sensors monitor real-time transmembrane pressure (TMP), magnetic field, and MLSS; AI algorithms predict and optimize backwash cycles, reducing downtime by 40%.

• Automated cleaning systems (chemical cleaning + air scouring) extend membrane lifespan to 5–8 years.

Strategic Advantages

Space & Cost Efficiency

• 50% smaller footprint than conventional plants (no sedimentation tanks).

• Operating cost savings of $0.12–0.20/m³ due to 70% reduction in treatment energy demand.

Water Reuse Compliance

• Meets stringent non-potable water reuse standards (e.g., China Class IV, US EPA 503); treated water can be reused for irrigation/cooling.

Operational Resilience

• Handles influent fluctuations (e.g., COD 200–1,500 mg/L) without performance loss; ideal for industrial shock loads.

Key Applications

1. Municipal Wastewater & Reuse

• Large-Scale WWTPs: Beijing Miyun Wastewater Treatment Plant (45,000 m³/day) employs hollow fiber MBRs, achieving 99% SS removal and enabling urban reuse.

• Decentralized Systems: Rural communities (e.g., Zhejiang villages) deploy containerized MBR units treating 50–500 m³/day, eliminating the need for sewage管网 (sewer networks).

2. Industrial Wastewater Treatment

3. Emerging Cases

• Nutrient Recovery: Extracts phosphorus and nitrogen for fertilizer production.

• Seawater Desalination Pretreatment: Reduces fouling potential in downstream reverse osmosis desalination processes.
