FRP Vessel –
High-Performance, Corrosion-Resistant Water Treatment Tank
Overview
The FRP Vessel (Fibreglass
Reinforced Plastic Vessel) is a state-of-the-art pressure tank widely used
in water treatment systems for filtration, softening, and purification.
Designed using advanced composite materials, the vessel combines lightweight
durability, chemical resistance, and high strength, making it a perfect
alternative to traditional metal tanks. Its robust construction and
corrosion-free design ensure consistent performance and a long service life,
even in harsh environments.
Whether you are setting up a domestic
RO system, an industrial water filtration plant, or a commercial softening unit,
an FRP Vessel provides unmatched reliability, safety, and efficiency in water
storage and pressure management.
Detailed Description
FRP (Fibreglass Reinforced
Plastic) Vessels are modern, high-strength composite pressure tanks made using
a combination of polyethylene (PE) inner liners and fibreglass outer
shells reinforced with epoxy resin. The result is a vessel that is lightweight,
corrosion-proof, and capable of handling high pressure — without the need
for heavy metal structures.
The inner shell is made
from food-grade polyethylene, ensuring safe contact with water and
preventing contamination. The outer layer, composed of multiple layers
of fibreglass and epoxy resin, provides the required mechanical strength and
protection against physical and chemical stress.
Unlike metal vessels that
corrode, rust, or react to chemicals over time, FRP Vessels remain unaffected
by most water treatment chemicals, making them ideal for applications involving
brine, chlorine, and other aggressive substances. This makes them the preferred
choice in industries and municipalities where performance, longevity, and
hygiene are critical.
Construction and Design
The FRP Vessel consists of three
major layers:
- Inner Shell (Liner):
- Made from high-density polyethylene (HDPE) or polypropylene
(PP).
- Ensures smooth, non-reactive, and hygienic water contact.
- Middle Layer:
- Reinforced with high-tensile fibreglass strands for
added strength.
- Provides excellent pressure-bearing capacity.
- Outer Shell:
- Coated with epoxy resin or UV-resistant materials.
- Offers a sleek finish and long-term protection from UV rays
and weathering.
Each vessel is designed to
withstand internal water pressure, external impact, and temperature
fluctuations while maintaining its structural integrity.
Working Principle
FRP Vessels are typically used
as housings for filter media such as sand, activated carbon, resin, or
multimedia. Water enters through the inlet, passes through the filtration
media, and exits as clean, treated water. The pressure inside the vessel helps
in effective filtration or ion exchange, depending on the application.
These vessels can handle both pressurised
flow systems and gravity-based systems, making them suitable for a
wide variety of uses — from domestic filtration to large-scale industrial
operations.
Key Features

Applications
FRP Vessels are versatile and
can be used in a wide range of water treatment and industrial systems,
such as:
- Residential
Water Softeners: For removing hardness and improving water quality.
- Commercial
Filtration Systems: Used in hotels, hospitals, and offices.
- Industrial
Water Treatment Plants: For filtration, demineralisation, and reverse
osmosis.
- RO
Pre-treatment and Post-treatment Units: Ideal for pre-filters and
polishing filters.
- Agricultural
Irrigation Systems: For filtering water used in drip irrigation.
- Municipal and
Public Water Supply Systems: For large-scale purification and
distribution.
- Chemical and
Process Industries: Resistant to acids, alkalis, and other aggressive
chemicals.
Advantages
- Superior Durability: Long-lasting design that withstands
high pressure and continuous operation.
- Corrosion-Free: Ideal for long-term use with no risk of
rust or oxidation.
- Lightweight & Easy Handling: Significantly lighter
than metal tanks, making transport and installation simpler.
- Safe & Hygienic: Food-grade inner liner ensures safe
water storage without odour or contamination.
- Customisable Design: Available in multiple sizes,
pressure ratings, and inlet/outlet configurations.
- Low Maintenance Cost: Requires minimal cleaning and no
special coatings.

Installation and Maintenance
Installing an FRP Vessel is
simple and does not require heavy equipment. The vessel is typically mounted
vertically using a PP or FRP base. It can be connected directly to multi-port
valves, manifolds, or piping systems depending on the application.
Maintenance Tips:
- Clean or replace filter media periodically.
- Check for leaks or cracks once every 6–12 months.
- Avoid exposure to direct fire or extremely high temperatures.
- Always follow manufacturer guidelines for safe operation.
With basic care, an FRP Vessel
can serve efficiently for over a decade without major maintenance.
