High-Performance SWRO Membrane MR-SW-4040 - Industrial Seawater Desalination Solution

Guangdong Morui's enterprise-grade swro membrane MR-SW-4040 delivers exceptional seawater desalination performance for industrial applications. With 99.5% salt rejection rate and 1400 GPD flow capacity across 7.9m² active area, this advanced membrane operates efficiently at 5.5-7 MPa pressure. Our thin-film composite architecture withstands harsh marine environments while maintaining structural integrity. Backed by 19 years of manufacturing expertise and 500+ engineering professionals, this membrane serves Fortune 500 companies including Foxconn, CATL, and BYD across 14 global locations.

What is SWRO Membrane Technology?

Our product represents cutting-edge semi-permeable barrier technology. It overcomes high osmotic pressure in seawater containing 30,000-50,000+ ppm Total Dissolved Solids.

Your facility needs reliable freshwater generation from ocean sources. Our membranes feature sophisticated thin-film composite architecture. This includes polyester support web, polysulfone intermediate layer, and cross-linked aromatic polyamide surface.

Unlike standard brackish water membranes, our product withstands 800-1,200 psi operating pressures. You get consistent performance without structural compromise.

Key advantages include:

• Minimized Specific Energy Consumption (SEC)
• Enhanced biofouling resistance in warm water
• High boron rejection meeting WHO standards (<0.5 mg/L)
• Extended lifespan in high-salinity environments

Product Specifications

Applications Across Industries

Large-Scale Municipal Desalination

Your municipal water authority requires millions of gallons daily processing capacity. Our product systems handle fluctuating intake water quality efficiently. You benefit from competitive Levelized Cost of Water compared to traditional sources.

Offshore Oil & Gas Operations

FPSO and drillship applications demand compact, high-productivity solutions. Your offshore facility gets reliable process and potable water generation. Our robust fiberglass construction withstands constant motion and physical stress.

Island Resorts & Remote Industrial Sites

Remote locations need reliable water supply for business continuity. You minimize downtime with our fouling-resistant membrane design. Technical support logistics become manageable with extended maintenance intervals.

Industrial Manufacturing

Electronics, automotive, and battery manufacturers require consistent water quality. Your production line gets stable output meeting strict quality standards. Our swro membrane technology supports continuous operation requirements.

Advanced Technical Properties

Our membrane technology delivers superior performance through carefully engineered specifications:

Salt & Boron Rejection:

• Stabilized salt rejection: 99.5% minimum
• Boron rejection: 90-93% at standard conditions
• Single-pass potable water generation capability

Enhanced Durability:

• Chemical stability during CIP procedures (pH 1-13)
• Pressure compaction resistance under high-pressure operation
• Extended operational lifespan in harsh conditions

Optimized Flow Design:

• Low-differential-pressure feed spacer geometry
• Reduced pressure drop across membrane surface
• Enhanced biofouling mitigation

Quality Assurance & Testing

Every membrane undergoes rigorous inspection before shipment:

Wet Testing Verification:

Each element tested at 32,000 ppm NaCl, 800 psi, 25°C. You receive performance verification against datasheet specifications with ±15% flow variance tolerance.

Integrity Testing:

Vacuum decay testing ensures assembly integrity. We verify glue lines and eliminate bypass leaks between permeate and feed channels.

Preservation Standards:

Your product arrives preserved in 1% Sodium Metabisulfite solution. Vacuum-sealed packaging prevents biological growth during storage and transport.

Installation & Maintenance Guidelines

Pre-Treatment Requirements:

• Feed water SDI <3.0 recommended
• Proper media filtration or UF upstream
• Chemical dosing for scale prevention

Cleaning Protocols:

Perform CIP when:

• Normalized permeate flow drops 10-15%
• Salt passage increases 5-10%
• Differential pressure increases 15%

Temperature Considerations:

For every 1°C temperature increase, expect ~3% flux increase. Your system needs VFD controls for pressure adjustment during seasonal fluctuations.
