The Technology Behind Modern RO Membranes

Core Membrane Materials

Our advanced RO membranes utilize:

1. Polyamide Thin-Film Composite (TFC): The industry gold standard, featuring:

A ultra-thin (100-200 nm) polyamide rejection layer

Porous polysulfone support layer

Non-woven polyester backing for strength

2. Nanocomposite Enhancements: We incorporate:

Graphene oxide nanoparticles for improved flux

Antimicrobial additives to resist biofouling


Compared to conventional cellulose acetate membranes, our TFC membranes offer:

1. 2-3x higher water flux

2. 50% better salt rejection

3. 3-5x longer lifespan*

Our Proprietary Manufacturing Process

Step 1: Precision Polymer Synthesis

Controlled interfacial polymerization creates the ultra-thin polyamide layer

Strict temperature (±0.5°C) and humidity (±2%) controls ensure consistency

Step 2: Automated Membrane Casting

Computer-controlled extrusion applies the active layer at 1-2 micron accuracy

In-line optical scanners detect defects early

Step 3: Quality Validation

Every membrane undergoes:

Bubble Point Testing - Verifies pore size uniformity

Salt Rejection Testing - Measures NaCl rejection at 2000 ppm, 225 psi

Longevity Simulation - 500+ hour accelerated life testing

*Our defect rate is <0.1% - 10x better than industry average*


Breakthrough Innovations in RO Technology

1. Low-Energy Desalination Membranes

Specialized surface patterning reduces energy needs by 30-40%

Ideal for seawater applications (tested at 45,000 ppm TDS)

2. Anti-Fouling Hybrid Membranes

Zwitterionic polymer coating reduces fouling by:

80% less bacterial adhesion

65% less mineral scaling

3. High-Temperature Industrial Membranes

Stable up to 90°C (vs. standard 45°C limit)

Perfect for food processing and chemical applications

We hold 12 patents on membrane innovations, with 5 more pending

Rigorous Quality Control Standards

Our membranes meet or exceed:

1. NSF/ANSI 58 & 61 - Drinking water safety

2. FDA 21 CFR 177 - Food contact compliance

3. ISO 9001:2015 - Quality management

4. ASTM D4194 - Standard test methods


Each production batch includes:

37 distinct quality checks

Third-party validation testing

Full traceability documentation
