Engineered fibre-reinforced polymer vessels for reverse osmosis membrane housing and multi-media pre-treatment filtration across industrial and commercial water systems.
Our fibre-reinforced polymer (FRP) pressure vessels are designed to house standard 4", 8", and 16" diameter RO membrane elements, delivering outstanding structural integrity at operating pressures up to 600 psi. The smooth internal liner prevents biofilm accumulation and provides years of trouble-free performance in seawater, brackish water, and high-TDS applications.
In addition to membrane housings, we supply FRP multi-media and sand filter vessels for pre-treatment stages. Available in a wide range of diameters and with top or side-mount port configurations, these vessels are the backbone of reliable RO and filtration systems worldwide.
Standard 4" diameter vessels accommodating 2- to 7-element configurations. Ideal for small to medium commercial RO systems, rated up to 300 psi operating pressure with end-port or side-port options.
Industry-standard 8" diameter vessels for large industrial RO plants. Typically houses 6 membrane elements in series, engineered for pressures up to 600 psi in seawater desalination duty.
Large-diameter 16" vessels designed for high-capacity industrial and municipal RO plants. Constructed from premium-grade FRP with internal thermoplastic liner for chemical resistance and longevity.
Carbon-fibre composite pressure vessels offering reduced weight with superior pressure ratings. Suitable for skid-mounted systems and mobile water treatment units where weight is a critical factor.
Large-diameter FRP filter vessels for multi-media, sand, carbon, and softener applications. Available in manual or automatic backwash configurations, suitable for flow rates from 1 to over 200 m³/h.
Purpose-built FRP vessels for pressure sand filtration of turbid water. Corrosion-proof construction handles aggressive raw-water chemistries that would damage conventional steel tanks.
All vessels meet NSF/ANSI 61 and relevant international standards, ensuring safe contact with drinking water and compliance with project specifications.
FRP construction eliminates rust and corrosion, outperforming steel vessels in saline, acidic, and chemically aggressive water conditions without costly protective coatings.
Rated for operating pressures from 150 psi to 600 psi depending on model, with a safety factor exceeding 3:1 for reliable, leak-free operation over the system's lifetime.
UV-stabilised outer winding and chemically inert inner liner deliver a design life exceeding 15 years, minimising total cost of ownership across demanding industrial applications.
Brackish water, seawater, and low-energy membrane elements sized for your 4" or 8" vessels.
View Range →Silica sand, anthracite, and AFM glass media to fill your FRP multi-media filters.
View Range →Vertical multistage and sea water pumps for pressurising RO feed to your vessels.
View Range →High-pressure RO fittings, interconnect manifolds, and valves for vessel arrays.
View Range →We supply 4" RO vessels (for 4"×40" elements), 8" RO vessels (for 8"×40" elements), 16" large-diameter composite vessels for high-capacity industrial systems, and FRP multi-media and sand filter vessels. Composite vessels are also available for high-pressure SWRO service up to 600 PSI.
Yes. Our FRP pressure vessels are NSF/ANSI 61 certified for potable water contact, and manufactured to ASME and ISO standards. Full certification documentation, test certificates, and data sheets are provided with each supply.
Standard FRP vessels are rated to 300 PSI (21 bar) - sufficient for most BWRO applications. For SWRO high-pressure service, we supply composite vessels rated to 600 PSI (41 bar). Contact us with your operating pressure and membrane configuration for the right vessel recommendation.
Yes. FRP and composite pressure vessels are the standard choice for SWRO desalination plants across UAE, Saudi Arabia, Qatar, and Oman. FRP is inherently corrosion-resistant to chloride - making it far superior to metallic alternatives in the Gulf's high-temperature, high-chloride seawater environment.
