Permionics Membranes

Permionics is a pioneer in membrane technology with over 50 years of experience in developing high-quality liquid separation solutions. Based in India, we are the first indigenous manufacturer of RO (Reverse Osmosis), UF (Ultrafiltration), and NF (Nanofiltration) membranes. Our technologies serve a wide range of industries from water purification to biotechnology and food processing.

We offer a diverse portfolio of membrane solutions, including:

1. RO Membranes with HPA Technology
2. Flat Sheet Membranes (MF, UF, NF, RO)
3. Spiral-Wound Membranes for industrial and sanitary use

These products are available in various molecular weight cut-offs (MWCO), polymer chemistries, and configurations tailored to your specific application.

HPA (High Performing Architecture) Technology is a proprietary innovation by Permionics that:

1. Enhances membrane performance and water quality
2. Increases durability and operational lifespan
3. Delivers cost-efficiency
4. Minimizes environmental impact through reduced waste and energy use

This makes our RO membranes ideal for industries needing high-purity water with long-term reliability.

Flat Sheet Membranes are versatile, customizable membrane sheets used in:

1. Water and wastewater treatment
2. Biopharma and food industries
3. Chemical processing

They are available in various polymers, such as:

1. PVDF
2. Modified and Unmodified PES
3. Polysulfone (PS)
4. Polyamide (PA)

Their key benefits include high flux, chemical resistance, temperature resilience, and precise MWCO control.

Spiral-Wound Membranes are compact, high-efficiency membrane modules widely used in:

1. Pharmaceuticals & biotechnology
2. Food & beverage processing
3. Chemical & general industrial applications

With variable feed-spacer thickness (28–120 mil), they accommodate fluids of different viscosities and solid content, optimizing energy use and hydrodynamics. Specialized models are available for acidic/caustic solvents and high-temperature environments.

Our membranes support a broad range of industries including:

1. Water & Wastewater Management
2. Pharmaceuticals & Biotech
3. Food & Beverage
4. Chemical Processing
5. Electronics & Semiconductors
6. Textiles & Dye Industries

Each product is engineered to meet industry-specific regulatory standards, quality needs, and environmental expectations.

Sustainability is at the core of our innovation:

1. Our membranes reduce water waste, chemical usage, and energy demand
2. Extended membrane life means fewer replacements and lower lifecycle cost
3. We focus on zero-liquid-discharge (ZLD) and eco-friendly processing

Yes, we offer tailored membrane solutions based on:

1. Desired MWCO
2. Chemical compatibility
3. Thermal requirements
4. Module format (flat sheet or spiral)

Our R&D team works closely with clients to develop application-specific products that solve unique separation challenges.

Lifespan depends on the application, operating conditions, and maintenance. However, thanks to innovations like HPA Technology, our membranes often outlast standard membranes, offering long-term performance and cost benefits.

MWCO (Molecular Weight Cut-Off) refers to the smallest molecular size a membrane can retain. Choosing the correct MWCO is crucial to:

1. Ensure desired separation accuracy
2. Maintain process efficiency
3. Optimize product quality

Permionics offers membranes with precisely defined MWCO ranges, allowing for fine-tuned separation in critical applications.

Yes. We offer membranes engineered for aggressive chemical environments and elevated temperatures, including:

1. Acid- and caustic-resistant membranes
2. High-temperature-compatible spiral membranes

These are ideal for CIP cycles, industrial solvents, and specialty chemical processes.

Our membranes are designed with:

1. Fouling-resistant surface chemistries
2. Optimized hydrodynamic flow paths
3. Low-energy operation profiles

These features reduce the frequency of chemical cleaning, lowering downtime and extending membrane life.

Permionics membranes comply with a range of international quality and safety standards relevant to:

1. Pharmaceutical-grade filtration
2. Food contact safety
3. Environmental regulations

We ensure traceability, validation support, and performance data across all sectors we serve.

Clients choose us for:

1. Proven membrane expertise spanning 5 decades
2. Custom-engineered solutions for niche applications
3. In-house R&D and manufacturing in India
4. Sustainable, cost-effective innovations that improve process outcomes
5. Our local expertise with global reach ensures fast support, consistent quality, and reliable performance.

The right membrane depends on:

1. Feedwater composition
2. Desired separation level (MWCO or salt rejection)
3. Operating temperature and pH
4. Flow rates and system design

Our technical team offers application support and pilot testing to help you identify the ideal membrane for your needs.
