RO Membrane (BW30-400)

1. Product Overview
The RO Membrane (BW30-400) is a high-rejection, polyamide thin-film composite membrane engineered for brackish water reverse osmosis desalination in large-scale industrial water treatment systems. Its primary application is the reduction of total dissolved solids (TDS), silica, and organic compounds from feedwater to produce high-purity permeate for critical processes. With an active area of 400 ft² and industry-standard 8” diameter, this membrane delivers a superior balance of low energy consumption and high flux, making it a strategically vital component for operations seeking to reduce water footprint while maintaining production uptime in the face of variable feedwater quality.

2. Key Specifications & Technical Characteristics

• Chemical Composition: Polyamide thin-film composite (TFC) on a polysulfone support layer; non-cellulosic, resistant to biological degradation and pH fluctuations (cleaning range: pH 1–13).

• Material Components: Wrapped with fiberglass outer shell for high-pressure durability; standard brine seal and U-cup end cap configuration.

• Performance Characteristics:

  • Nominal salt rejection: 99.5% (minimum 99.0% for NaCl)

  • Permeate flow rate: 10,500 GPD (39.7 m³/day) at standard test conditions

  • Active membrane area: 400 ft² (37.2 m²)

• Physical Form: Spiral-wound cylindrical module; color: off-white fiberglass outer wrap.

• Operating Limits:

  • Max operating pressure: 600 psi (41 bar)

  • Max feed temperature: 113°F (45°C)

  • Free chlorine tolerance: <0.1 ppm (destructive beyond this threshold)

• Packaging Options: Standard 1 unit/cardboard box with desiccant; palletized 30 units per industrial shipping pallet; custom vacuum-sealed for long-term storage.

• Shelf Life: 12 months from shipment if stored in factory-sealed bag, away from direct sunlight and temperatures between 35–95°F (2–35°C).

3. Core Industrial Applications

• Primary Industries:

  • Power generation (boiler feedwater makeup)

  • Petrochemical & refining (process water)

  • Food & beverage (CIP rinse and ingredient water)

  • Municipal water treatment (brackish groundwater remediation)

• Operational Use Cases:

  • Reducing TDS from 2,000–8,000 ppm to <50 ppm in a single pass

  • Pre-treatment for high-purity EDI or mixed-bed ion exchange systems

  • Silica removal up to 99% to prevent scaling on heat exchange surfaces

• Performance Advantages over Alternatives:

  • Higher active area (400 ft²) delivers 10–15% more permeate than legacy 380 ft² membranes at the same pressure → lower energy per cubic meter.

  • Superior boron and TOC rejection vs. generic Chinese or low-cost Indian membranes, critical for pharmaceutical and semiconductor feedwater.

  • Low-fouling spacer technology reduces cleaning frequency by up to 20% compared to standard 8” membranes, directly lowering OPEX.

4. Competitive Advantages

• Quality Consistency: Every batch is factory-tested with vacuum decay and bubble point; actual salt rejection data included with each serialized product. ISO 9001:2015 and NSF/ANSI 61 certified.

• Supply Reliability: Dual manufacturing sites (Asia-Pacific and Americas) with a 4-week lead time for orders up to 500 units; safety stock held in Rotterdam, Houston, and Shanghai.

• Logistics Capability: Direct-to-site FCL or LCL shipments with tamper-proof packaging and temperature/humidity data logger inclusion for sensitive projects.

• Price Competitiveness: Tier-one performance at 12–18% below major OEM list prices (Dow, Hydranautics equivalents) due to streamlined distribution via industrial marketplace.

• Sustainability: Lead-free end caps, fully recyclable inner core, and 30% reduction in packaging plastic vs. industry average. Eligible for green procurement credits in EU and North America.

• Technical Support: Full hydraulic design software access, online cleaning calculators, and 24-hour technical troubleshooting from in-house chemical engineers.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 12 units (single standard carton)

• BULK 20MT Loading Capacity: A 20-foot standard dry container holds:

  • 224 units (7 pallets × 32 units per pallet, stacked 2 high)

  • Total net weight approx. 1,900 kg (8.5 kg per unit including packaging) → well under 20MT, enabling co-loading of brine seals, o-rings, or chemical cleaning kits.

• Note for procurement: For full container optimization (20MT), combine with up to 2,000 units of 4” membranes or 20 drums of antiscalant. Contact logistics desk for customized pallet patterns.
