Brackish water, seawater (SWRO) and low-energy reverse osmosis membrane elements in 4-inch and 8-inch sizes, with salt rejection up to 99.7%. Supplied to water treatment and desalination plants across India, the Middle East, Africa and worldwide.
Genoasis is a trusted supplier of spiral-wound reverse osmosis membrane elements for industrial, municipal and desalination water treatment. We stock 4-inch and 8-inch elements from leading international membrane manufacturers, covering brackish water, seawater (SWRO), low-energy, and fouling-resistant grades - so you get the right element for your feed water chemistry and target permeate quality.
Every membrane is matched to your application: send us your feed water analysis and required flow, and our engineers run a membrane projection to recommend the optimal element, array and operating pressure - and quote the matching FRP pressure vessels, antiscalants and cartridge filters in the same package.
RO membranes are supplied across India (Chennai, Mumbai, Delhi, Bangalore, Hyderabad), the Middle East (UAE, Saudi Arabia, Qatar, Oman, Kuwait, Bahrain), and Africa (Nigeria, Kenya, South Africa, Ghana). We respond to every enquiry within 1 hour.

High-rejection BWRO elements for borewell and surface water from 1,500-10,000 ppm TDS. Available in standard, low-energy and fouling-resistant grades. 99.5%+ stabilised salt rejection.

High-pressure seawater elements with 99.7-99.8% salt rejection for single-pass desalination of feed up to 50,000 ppm TDS. Ideal for coastal and offshore desalination in the GCC and Africa.

Energy-saving elements that deliver rated flux at reduced feed pressure, cutting high-pressure pump power consumption and operating cost on brackish water RO systems.

Nanofiltration elements for selective softening and organics/colour removal, and ultrafiltration modules for RO pre-treatment and clarification down to 0.02 microns.
| Membrane Type | Element Sizes | Salt Rejection | Typical Feed TDS |
|---|---|---|---|
| Brackish Water RO | 2.5", 4", 8" | 99.5%+ | 1,500-10,000 ppm |
| Seawater RO (SWRO) | 4", 8" | 99.7-99.8% | up to 50,000 ppm |
| Low-Energy RO | 4", 8" | 99.0-99.5% | 500-5,000 ppm |
| Nanofiltration (NF) | 4", 8" | Selective | softening / organics |
Up to 99.8% salt rejection for consistent, high-purity permeate across brackish and seawater applications.
Low-energy grades reduce feed pressure and high-pressure pump power, cutting your operating cost per m3.
2.5-inch, 4-inch and 8-inch elements in stock, compatible with standard RO pressure vessels.

We supply brackish water, seawater (SWRO), low-energy and fouling-resistant RO membranes, plus NF and UF membranes, from leading international manufacturers. Both 4-inch and 8-inch spiral-wound elements are stocked, along with 2.5-inch elements for small systems.
Our seawater RO (SWRO) membranes achieve stabilised salt rejection of 99.7% to 99.8%, suitable for single-pass desalination of feed water up to 45,000-50,000 ppm TDS. Brackish water RO membranes achieve 99.5%+ rejection at lower operating pressures.
Yes. Send us your feed water analysis (TDS, ions, temperature, SDI) and required permeate flow. Our engineers run a membrane projection to recommend the optimal element type, array configuration and operating pressure, and quote the membranes and matching pressure vessels together.
Yes. We supply RO membranes across the Middle East (UAE, Saudi Arabia, Qatar, Oman, Kuwait, Bahrain), India, and Africa (Nigeria, Kenya, South Africa, Ghana, Tanzania, Ethiopia). We handle export documentation and shipping, and respond to enquiries within 1 hour.
Send your feed water analysis and flow requirement - we'll recommend the right membrane and quote it with matching vessels and chemicals.
