FRP Filter Vessel – 10 Inch × 54 Inch | UV Water Systems Oman

The FRP (fibreglass-reinforced plastic) pressure vessel is the standard containment vessel for bulk media filtration and ion exchange in residential and small commercial water treatment in Oman. Unlike stainless steel vessels, which require welding, surface finishing, and periodic inspection for corrosion, FRP vessels are manufactured from wound fibreglass and resin composite — they are corrosion-proof across the full pH range of potable water treatment, lighter than steel for equivalent pressure ratings, and completely maintenance-free for their service life (typically 10–15 years) under normal operating conditions. The 10-inch × 54-inch FRP vessel is the most widely used size in Oman for residential-scale water softeners (loaded with SAC cation exchange resin), activated carbon filters (loaded with GAC), multimedia filters (loaded with silica sand, garnet, and anthracite), and iron removal filters (loaded with Birm or manganese greensand). UV Water Systems supplies, loads, and commissions FRP filter vessels in all standard sizes across the Sultanate of Oman.

FRP Vessel Construction and Pressure Ratings

FRP pressure vessels are manufactured by filament winding — fibreglass strands are wound around a mandrel under tension at calculated angles to provide maximum hoop and axial strength, then impregnated with resin and cured. The finished vessel’s pressure rating depends on wall thickness and winding angle — standard 10-inch water treatment vessels are rated at 8–10 bar operating pressure, well above the 2–4 bar feed pressures typical in Oman residential and commercial water supply systems. The inner surface is lined with a smooth resin layer that is chemically inert to the media and water conditions encountered in water treatment — no leaching, no corrosion, and no biological growth on the smooth inner surface. FRP vessel tops (heads) incorporate threaded ports for multi-port valve connections, riser tube, gravel underbedding support screen, and distributor assembly.

Key Features and Benefits

Corrosion-proof fibreglass construction: FRP is unaffected by all water chemistries encountered in Oman water treatment — chlorinated municipal supply, high-TDS borehole water, softened water, acidic RO permeate, and regeneration chemicals (sodium chloride brine, hydrochloric acid, caustic soda) — no corrosion, pitting, or liner degradation across the vessel’s service life.
10-inch × 54-inch capacity — 1.5–2.0 ft³ media: The 10×54 vessel holds 1.5–2.0 cubic feet of filter media or ion exchange resin — sufficient for a residential water softener treating a 3–4 person household, a small residential iron removal unit, or a pre-treatment carbon filter for a 200–400 LPH RO system.
Standard multi-port valve thread interface: The 10-inch vessel top is threaded for standard 1-inch or 1.5-inch multi-port control valve connections (Runxin, Fleck, Autotrol) — compatible with automatic and manual backwash valves for softener regeneration and filter backwashing without custom adapters.
Lightweight for easy installation: FRP construction is approximately 60–70% lighter than a steel vessel of equivalent capacity — the empty 10×54 vessel can be positioned and installed by one person without lifting equipment, reducing installation cost for residential applications.
10-bar pressure rating: Well above Oman residential supply pressure (2–5 bar) and commercial water supply pressure (4–6 bar) — the vessel will not fail at normal operating pressures even if downstream valves close suddenly (water hammer conditions).

Frequently Asked Questions

What media can be loaded into a 10×54 FRP vessel? The 10×54 vessel can be loaded with SAC cation exchange resin (softener), GAC activated carbon (carbon filter), silica sand (sand filter), Birm iron removal media, manganese greensand, calcite (pH correction), or mixed bed resin — depending on the water treatment application. UV Water Systems loads the correct media type and quantity for your specific water quality and treatment objective.
