Reverse osmosis membrane 8040 type

Description

1. Product Overview
   Reverse osmosis membrane 8040 type is a spiral-wound thin-film composite (TFC) membrane element engineered for industrial water treatment and process water purification. It delivers high salt rejection and stable permeate flow for applications including boiler feedwater, ultrapure water production, desalination pre/post-treatment, and wastewater reuse. The membrane’s key value proposition is consistent high-performance separation with low specific energy and predictable fouling resistance, enabling lower operational cost and higher uptime. Strategically, this product addresses increasing regulatory and cost pressures on industrial water use by enabling modular, scalable, and energy-efficient treatment solutions across diverse geographies and feedwater qualities.

2. Key Specifications & Technical Characteristics

• Membrane type: Spiral-wound thin-film composite (TFC) reverse osmosis element, 8040 form factor (8″ diameter × 40″ length).

• Active layer material: Crosslinked aromatic polyamide (polyamide thin-film).

• Support layers: Non-woven polyester support, polysulfone backing, feed spacer (PET).

• Typical salt rejection: ≥99.0% for NaCl under standard test conditions (may vary with feed water).

• Typical permeate flux: 8–12 GFD (gallons per square foot per day) at 150 psi, depending on feed TDS and temperature.

• Operating pressure range: 150–600 psi (10–41 bar) (select model variants for high-pressure brackish or seawater service).

• Operating temperature range: 1–45 °C (extended ranges available on request).

• pH tolerance: Continuous operation pH 2–11 (cleaning limits per manufacturer guidelines).

• Chlorine tolerance: Low; requires dechlorination prior to service (standard TFC sensitivity).

• Maximum brine concentration: Up to 45,000 ppm TDS depending on element variant.

• Flow & connection: Standard 8040 feed/permeate/brine ports; flow orientation as per industry standard.

• Physical characteristics: cylindrical spiral-wound element, nominal active membrane area 36–40 m² per element (model-dependent).

• Weight (dry): ~11–14 kg per element (typical).

• Packaging options: Carton box with wooden pallet (12–24 elements per pallet), bulk crate, or custom export packaging with corrosion inhibitors and desiccant.

• Shelf life / storage: Recommended in original sealed packaging; shelf life 12–24 months if stored dry, away from direct sunlight and chlorine exposure.

• Quality & certification: Manufactured under ISO 9001 quality system; material traceability and batch test reports available on request.

3. Core Industrial Applications

• Power generation (boiler feed and cooling tower make-up): Provides high-rejection permeate to protect turbines and heat-exchange surfaces, reducing blowdown and chemical dosing.

• Semiconductor and electronics fabs (pre-RO/RO polishing stages): Enables tight control of ionic contaminants when paired with downstream polishing, improving yield and device reliability.

• Food & beverage processing (water for formulation and rinsing): Delivers consistent water quality to meet hygiene and taste standards while lowering ingredient and wastewater costs.

• Pharmaceutical & biotech (process water and utility systems): Supports compliance with water quality requirements for non-sterile utilities; used where predictable ionic control is needed before further polishing.

• Desalination pretreatment and brackish water RO systems: Effective in modular RO trains for municipal-industrial desalting and zero-liquid discharge (ZLD) schemes.

• Industrial wastewater reclamation and reuse: Recover high-quality permeate from process effluents, enabling water reuse and lowering freshwater intake and discharge costs.
  Why it outperforms alternatives:

• Higher salt rejection and stable flux over longer service intervals compared with commodity cellulose acetate or unoptimized membranes.

• Proven fouling resistance profile when combined with correct pretreatment (suspended solids and antiscalant dosing), reducing cleaning frequency.

• Modular 8040 format enables straightforward replacement, retrofit into standard housings, and predictable system scaling for CAPEX planning.

4. Competitive Advantages

• Quality consistency: Tight manufacturing tolerances and batch testing ensure predictable performance and traceable QA documentation for each lot.

• Supply reliability: Factory production schedules and regional inventory buffering ensure continuous availability for industrial-scale projects and maintenance contracts.

• Logistics capability: Export-ready packaging, flexible palletization, and support for container loading plans (20’/40’/40’HC) reduce inland handling and transit damage risk.

• Price competitiveness: Economies of scale for bulk 20 MT lot orders and negotiated supply agreements yield cost-per-element advantages versus spot purchases.

• Sustainability benefits: Extended element life and higher flux reduce energy and chemical consumption per m³ of treated water; recyclable support materials and reduced waste through element return programs available.

• Technical support & documentation: Comprehensive datasheets, system-matching guidance, cleaning protocols (CIP), installation manuals, and lab validation test reports available; technical hotline and project-level engineering support offered.

5. Commercial & Supply Information

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

• Loading capacity (per container): Typical loading estimates (subject to final packaging configuration):

  • 20 ft container: ~10–12 MT (approx. elements per container depends on palletization).

  • 40 ft container: ~20–24 MT.

  • 40 ft HC: ~22–26 MT.

• Lead time: Standard lead time 4–8 weeks from order confirmation for bulk production; expedited capacity possible with premium routing.

• Incoterms & logistics: FOB, CIF, EXW available; export packing, fumigation, and documentation (COO, commercial invoice, packing list, test certificates) included per contract.

• Warranty & returns: Performance warranty per element for specified operational conditions; warranty terms and RMA procedures provided with sales contract.
