Hollow fiber membrane module

Description

1. Product Overview
   Hollow fiber membrane module designed for high-performance separation and filtration in industrial liquid and gas processing. Engineered for crossflow and dead-end filtration applications, it delivers high flux, tight retention control, and low fouling for processes such as water and wastewater treatment, ultrafiltration/nanofiltration pre-treatment, biotechnology downstream processing, and process water recovery. The module’s compact, high surface-area design maximizes throughput per footprint, reduces operating energy and footprint costs, and enables predictable, scalable performance for industrial operators. Strategically, this module supports regulatory compliance, circular water use, and cost-to-serve reductions—making it a core component in capital and operating expenditure optimization for large-scale industrial projects.

2. Key Specifications & Technical Characteristics

• Membrane material: Polyethersulfone (PES) or Polyvinylidene fluoride (PVDF) options; custom materials (e.g., polysulfone) available on request.

• Pore size / nominal molecular weight cut-off (NMCO): Typical range ultrafiltration 0.01–0.1 µm (10–100 nm); alternative pore sizes available for microfiltration or tighter ultrafiltration grades.

• Module configuration: Hollow fiber bundled module, potting at both ends, single- or multi-stage housings.

• Effective membrane area: Configurable; standard modules from 10 m² to 200 m² per module; custom sizes available.

• Operating temperature range: -5°C to 60°C (material-dependent).

• Maximum transmembrane pressure (TMP): Up to 3 bar typical for UF; higher ratings available for reinforced configurations.

• Flux performance: High intrinsic flux (>100 L/m²·h under standard test conditions), subject to feed characteristics and operating parameters.

• Chemical compatibility: Resistant to common cleaning agents (alkaline, acidic, chlorine tolerance varies by material—PVDF offers higher chemical resistance).

• Physical characteristics: Lightweight composite module, color: black/dark grey (membrane), module housings: stainless steel or FRP options, typical module length 0.5–2.0 m.

• Fouling mitigation features: Optimized fiber packing density, large bore feed channels, backwash and air-scour compatible.

• Packaging options: Individual sealed modules in corrosion-resistant crates; palletized shipments; bulk-packed skids for project deployments.

• Shelf life/storage: Stable in dry, ambient-controlled storage for 12 months; recommended storage 5–30°C, humidity <65%.

• Quality & certifications: Manufactured under ISO 9001 systems; material certificates and test reports supplied with each shipment.

3. Core Industrial Applications

• Municipal and industrial water & wastewater treatment: Primary use as UF pre-treatment for RO systems, tertiary filtration for reuse, and suspended solids removal. Reliable high-recovery operation reduces freshwater intake and discharge volumes.

• Food & beverage and dairy processing: Clarification, concentration, and microbial reduction while preserving organoleptic properties; hygienic module options and clean-in-place (CIP) compatibility.

• Biopharmaceutical and biotech downstream: Cell harvest, clarification, and concentration where controlled cut-off and low shear are required; validated options for GMP-adjacent workflows.

• Chemical and petrochemical process streams: Solids-liquid separation, catalyst recovery, and effluent polishing with robust chemical resistance options.

• Mining and metals: Tailings consolidation, process water recovery, and recycle streams to reduce freshwater demand and disposal costs.
  Why it outperforms alternatives:

• Higher specific surface area yields greater throughput per footprint versus flat-sheet solutions.

• Optimized fiber geometry lowers fouling propensity and supports effective backwash, extending run-times and reducing CIP frequency.

• Material options and reinforced housings enable operation across broader chemical and temperature windows, reducing replacement frequency and lifecycle cost.

4. Competitive Advantages

• Quality consistency: Factory-controlled fabrication, 100% integrity testing, and batch traceability ensure repeatable performance for scaled deployments.

• Supply reliability: Production capacity aligned with industrial project timelines; strategic inventory hubs and scheduled manufacturing slots reduce lead times for bulk orders.

• Logistics capability: Modular design optimized for container packing efficiency; available loading plans and FOB/CIF shipping coordination for global delivery.

• Price competitiveness: Scalable pricing for project volumes with tiered discounts at bulk thresholds and long-term supply agreements.

• Sustainability: Enables water reuse and reduced effluent volumes; modules designed for long life and reduced chemical consumption through efficient cleaning cycles.

• Technical support & documentation: Detailed datasheets, hydraulic and P&ID integration guidance, cleaning and validation protocols, and application engineering support available pre- and post-sale.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20MT.

• Loading capacity (MT per container): Dependent on module size and packaging; typical guide: 20-foot container up to 18–22 MT, 40-foot container up to 24–26 MT, subject to final packing configuration and shipping regulations.

• Lead times: Standard lead time quoted per purchase order and production schedule; expedited manufacturing available for prioritized projects (contact sales for confirmation).

• Terms & documentation: Commercial quote includes material test certificates, QC inspection reports, and shipping documentation.
