UF Membrane (PVDF UF 0.03µm)

Description

1. Product Overview

The PVDF UF 0.03µm membrane is an advanced ultrafiltration solution engineered for high-precision separation in demanding aqueous streams. Primarily deployed in pre-treatment for reverse osmosis (RO), drinking water purification, and industrial wastewater reuse, this membrane delivers superior particulate, bacterial, and viral removal with a sharp 0.03µm cutoff. Its strategic market value lies in enabling facilities to achieve regulatory compliance (e.g., EPA, EU DWD) while reducing downstream RO fouling by >40%, directly lowering total cost of ownership (TCO) in large-scale water treatment.

2. Key Specifications & Technical Characteristics

• Chemical Composition: Hydrophilic polyvinylidene fluoride (PVDF), oxidation-resistant

• Pore Size Rating: 0.03µm absolute (nominal retention rating: >99.99% for bacteria & viruses)

• Physical Form: Hollow fiber membranes; available in cartridge, pressure vessel, or module cassettes

• Color: Natural white to off-white

• Fiber Inner/Outer Diameter: 0.7mm / 1.3mm (typical industrial standard)

• pH Stability Range: 2 – 11 (continuous operation)

• Maximum Operating Temperature: 40°C (104°F)

• Packaging Options: Dry preservation (standard) or wet/glycerin-preserved in sealed polyethylene bags + export cartons or palletized crates

• Shelf Life: 24 months when stored in original dry packaging at 5–35°C, away from UV and ozone

3. Core Industrial Applications

• Primary Industries: Municipal water utilities, power generation (cooling water), food & beverage processing, pharmaceutical WFI pre-treatment, semiconductor ultrapure water, and oil & gas produced water.

• Operational Use Cases:

  • Pre-RO filtration in seawater desalination (SWRO) and brackish water RO (BWRO)

  • Final polishing for drinking water kiosks / decentralized community systems

  • Membrane bioreactor (MBR) tertiary treatment for industrial effluent recycling

• Performance Advantages: The 0.03µm cutoff surpasses standard 0.1µm UF by removing smaller virus particles (e.g., MS2 coliphage) without chemical dosing. PVDF provides high chlorine tolerance (up to 5000 ppm·h) enabling aggressive chemical cleaning – extending membrane life by 25–30% vs. PES or PS alternatives. Lower fouling propensity reduces backwash frequency, cutting operational energy use by ~15%.

4. Competitive Advantages

• Quality Consistency: Batch-to-batch integrity tested with bubble-point and pressure decay; each module certified for log reduction value (LRV ≥ 4 for viruses).

• Supply Reliability: Dual-source production lines (Asia & EU) with buffer inventory at regional hubs – guaranteed lead times ≤14 days for standard quantities.

• Logistics Capability: Pre-certified for sea, air, and rail transport with tamper-evident packaging; emergency spare parts access within 48 hours.

• Price Competitiveness: Tier-1 PVDF formulation at 15–20% lower price per m² than legacy European brands, driven by automated casting lines and direct polymer sourcing.

• Sustainability: Dry-packaged modules reduce shipping weight/CO₂ by 30% vs. wet alternatives; PVDF is fully recyclable at end-of-life (take-back program available for >100 modules).

• Technical Support: Free hydraulic design software (access), on-site commissioning support, and 10-year performance curve documentation.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 200 m² of membrane area (approx. 4 standard industrial modules)

• BULK 20MT Loading Capacity: Approx. 25,000 m² of membrane area (equivalent to ~500–600 modules) per 20FT dry container, depending on module size and packaging configuration
