BW30FR-4040 Anti-Fouling Brackish RO Element | RO membrane wholesale Supplier
Product Overview
As a professional RO membrane wholesale supplier with complete industrial Liquid Filterssupply chains, we provide bulk interchangeable BW30FR-4040 anti-fouling brackish RO elements for global water treatment distributors, EPC contractors and industrial plant operators. The BW30FR series is a classic anti-fouling brackish RO line from Dupont Filmtec product system, specially engineered for surface water, municipal secondary effluent and light industrial wastewater with moderate organic pollutants.
Most standard brackish RO membranes suffer fast biofouling and organic buildup when processing water containing humus, protein and colloids, requiring frequent CIP cleaning and short service cycles. BW30FR-4040 solves this industry pain point via hydrophilic modified polyamide surface and wide 34mil feed spacers, effectively slowing organic & microbial adhesion. All dimensions fully match original BW30 pressure vessels for direct replacement without equipment reconstruction. For clients looking to purchase large volumes, our RO membrane wholesale program offers tiered bulk discounts, customized packaging and worldwide door-to-door delivery support.
Working Principle
BW30FR-4040 follows the standard solution-diffusion separation mechanism of thin-film composite brackish RO membranes, with two targeted anti-fouling upgrades compared to ordinary BW models:
Hydrophilic surface graft treatment lowers surface hydrophobicity, repelling organic molecules and preventing biofilm attachment during long-term continuous operation.
Wide-flow corrugated feed spacers strengthen cross-flow turbulence, reduce concentration polarization and cut the accumulation of suspended solids on membrane surface.
After standard acid & alkaline cleaning cycles (pH 1.0–13.0, max 2 hours per wash, ≤35°C), the element can recover 90%+ of original flux and over 98% nominal salt rejection, delivering stable long-cycle operation for moderate-pollution brackish water sources.
Core Technical Specifications
All test indicators comply with global industrial RO standards, fully compatible with standard 8-inch pressure vessels:
Model: BW30FR-4040 Anti-Fouling Brackish RO Element
Standard Test Condition: 25°C, 155 psi, 2000 ppm NaCl, 15% recovery
Nominal Salt Rejection: ≥99.2% (minimum guaranteed 99.0%)
Nominal Permeate Flux: 7600–8000 GPD (±5% manufacturing tolerance)
Recommended Operating Pressure: 140–280 psi
Continuous Temperature Range: 15–40°C; 2-hour max emergency exposure at 45°C
Continuous Operating pH: 2.0–10.0; cleaning pH window 1–13
Maximum Feed SDI: ≤3

Allowed Feed COD: ≤300 mg/L (suitable for moderate organic wastewater)
Feed Water Operating Limits
BW30FR-4040 applies to brackish water with TDS ≤5000 ppm, SDI ≤3, no continuous free chlorine. Raw water exceeding COD 300 mg/L or SDI >3 requires advanced pretreatment before membrane installation.
Key Product Advantages
Outstanding Anti-Fouling Performance
Hydrophilic coating + wide spacer design extends chemical cleaning intervals by 30% compared to ordinary BW30 standard membranes, lowering chemical consumption and plant downtime. Ideal for surface water, municipal reuse and food processing wastewater.
1:1 Direct Replacement Compatibility
Standard BW30-4040 outer size, end cap and flow channel structure enable plug-and-play swap. No pump, vessel or pipeline modification needed during system retrofits, saving construction labor cost for bulk project upgrades.
Competitive RO membrane Wholesale Bulk Pricing
As direct factory RO membrane wholesale supplier, we launch tiered discount policies based on order quantity. Larger orders enjoy lower unit prices, free datasheets and third-party test reports for tender bidding.
Stable Post-Cleaning Recovery
After repeated acid/alkaline washing, flux and salt rejection maintain high levels, avoiding irreversible performance decay common in low-cost generic anti-fouling membranes. Annual replacement frequency drops for medium & large water plants.
Complete Global Supply Support
Vacuum-sealed anti-dry packaging for long-distance sea freight; OEM labeling, custom carton packaging and mixed container loading available for wholesale distributors.
Suitable Application Scenarios
Municipal wastewater reuse & secondary effluent treatment stations
River/lake surface water purification projects
Food & beverage factory process water systems
Light industrial brackish water recycling lines
Water treatment plant retrofit & membrane replacement projects
Unsuitable Working Conditions
Seawater desalination (TDS over 10,000 ppm, choose dedicated SW series seawater RO)
High-strength industrial wastewater with COD >300 mg/L
Systems with persistent unneutralized free chlorine
Raw feed SDI consistently above 3 without multimedia filtration

FAQ
Q1: What makes BW30FR-4040 different from regular BW30 RO membranes?
A1: BW30FR adopts hydrophilic anti-fouling surface treatment and wider feed spacers to resist organic and biological contamination, greatly extending cleaning cycles, while standard BW30 membranes lack dedicated anti-fouling design. We supply this model at favorable prices via our RO membrane wholesale program.
Q2: Can BW30FR-4040 directly replace old BW30-4040 elements?
A2: Yes, all outer dimensions, end caps and flow channels are fully matched, no system modification required. Minor pressure fine-tuning after installation is enough to restore rated flux.
Q3: What bulk support can your RO membrane wholesale supplier provide?
A3: We offer quantity-based discounts, customized packaging, full tender documents and global shipping. We also provide free water treatment design guidance for wholesale clients.
Q4: What pretreatment is required for BW30FR-4040 stable operation?
A4: Feed SDI ≤3, all free chlorine fully removed, operating pH controlled within 2–10. Submit full water lab reports to our engineering team for custom anti-scalant and recovery suggestions.
Q5: Is BW30FR-4040 suitable for seawater treatment?
A5: No, this is brackish anti-fouling RO element for TDS ≤5000 ppm. For seawater desalination, select our SW series seawater RO membranes.
