FRP Filter Vessel 36 Inch x 72 Inch – UV Water Systems Oman

Description

FRP Filter Vessel – 36 Inch × 72 Inch | UV Water Systems Oman

The 36-inch × 72-inch FRP pressure vessel is the largest standard single-vessel size in UV Water Systems’ filter vessel range — designed for industrial and large commercial water treatment applications where a single vessel must handle flow rates that would require two or more 24-inch vessels in parallel. At 36 inches (914 mm) internal diameter, the vessel provides 6.5 square feet (0.60 m²) of cross-sectional filtration area — at standard multimedia filter loading rates of 8–12 m/hour, this delivers a rated flow capacity of 5–7 m³/hour from a single vessel. This makes the 36×72 FRP vessel suitable as the primary sand filter or multimedia pre-treatment unit for industrial RO plants producing 3,000–6,000 LPH, the backwash pre-filter for industrial cooling towers and boilers in Oman’s industrial parks, and the primary iron and suspended solids removal stage in borehole water treatment systems serving industrial facilities. UV Water Systems supplies and commissions 36×72 FRP vessels as part of complete industrial water treatment skids for Oman’s industrial and healthcare sector clients.

Industrial Filter Sizing with the 36×72 Vessel

Industrial water treatment design in Oman must account for the worst-case inlet water quality — borehole water in Muscat’s industrial areas can reach 5,000–8,000 mg/L TDS with elevated iron, manganese, and suspended solids that require robust pre-treatment before RO membranes or boiler feed treatment. A 36×72 multimedia filter loaded with silica gravel, silica sand, and anthracite provides the pre-treatment capacity to protect RO membranes and downstream treatment equipment from the fouling that Oman’s high-solids borehole water causes without the pre-treatment stage becoming the capacity bottleneck. UV Water Systems engineers the media loading — gravel support layer, sand bed depth, anthracite cap layer — for each project’s specific flow rate, inlet turbidity, and suspended solids loading to achieve effluent turbidity below 1 NTU for UV and RO feed water standards.

Key Features and Benefits

• 5–7 m³/hour single-vessel capacity: The largest standard single FRP vessel in the range handles the pre-treatment needs of industrial RO plants up to 5,000–6,000 LPH without multi-vessel parallel configurations — simplifying industrial plant design and reducing installation footprint in Oman’s industrial water treatment facilities.
• 20–25 ft³ media capacity: Accommodates full industrial multimedia loading (gravel support, sand, anthracite) with adequate freeboard for backwash expansion, or large-scale SAC resin loading for industrial water softeners treating hardness for boiler feed or process water conditioning.
• 2.5-inch flange top port for industrial multi-port valves: Threaded and flanged top connection for industrial multi-port control valves (2.5-inch flange series) and motorised backwash valves used in automated industrial filter systems with programmable logic controller (PLC) backwash scheduling.
• Full FRP corrosion resistance at industrial operating conditions: FRP construction handles the aggressive water chemistries of industrial borehole water treatment including elevated iron, sulfate, and dissolved gases without corrosion or liner failure across the vessel’s 10–15 year design life.
• UV Water Systems industrial installation capability: UV Water Systems has the technical team and site installation experience to position, plumb, media-load, and commission 36×72 FRP vessels at industrial sites in Muscat — including connections to industrial pump systems, instrumentation, and automated control panels.

Applications Across Oman

The 36×72 FRP vessel is used in industrial RO plant pre-treatment, hospital water treatment systems, large hotel multimedia filtration, industrial softeners for boiler feed conditioning, and borehole iron removal systems across Muscat and Oman. UV Water Systems designs and delivers complete industrial filter skids incorporating 36×72 FRP vessels with media loading, control valves, and instrumentation to Oman industrial sites.

Frequently Asked Questions

Does a 36×72 FRP vessel require any structural support or civil works for installation? A fully loaded 36×72 FRP vessel (media + water) can weigh 800–1,200 kg — it requires a concrete or structural steel pad foundation rated for this load, and vertical support straps or clamps to prevent vessel movement under backwash pressure. UV Water Systems specifies foundation requirements and installs the support structure as part of industrial filter installations. Contact us for site-specific installation engineering.

What is the backwash flow rate required for a 36×72 multimedia vessel? Multimedia backwash requires 16–20 m/hour upflow velocity for bed fluidisation and solids flushing — for a 36-inch vessel with 0.60 m² cross-section, this equals 10–12 m³/hour backwash flow for 10–15 minutes per cycle. UV Water Systems includes backwash pump sizing and drain pipeline sizing in the design of all industrial filter systems to ensure effective backwash without compromising the media bed or vessel integrity.
