FRP Vessel For Water Treatment

 

The 4872 FRP Vessel for Water Treatment is a heavy-duty composite pressure tank designed for industrial, municipal, and desalination pretreatment systems.
Built with food-grade PE inner liner and epoxy fiberglass housing, INK-BLUE provides outstanding corrosion resistance, strength, and service life beyond 15 years.

This vessel supports a 15–25 m³/h flow rate, easily handling large-scale water filtration, softening, or chemical dosing. Whether installed in a reverse osmosis (RO) unit or an industrial wastewater treatment plant, it ensures consistent performance under varying pressures and temperatures.

 

 

 

🔹 Large Capacity: 1750 L (462 gallons) effective volume, ideal for community-level or industrial-scale systems.

🔹 High Pressure Tolerance: 150 PSI working pressure; burst pressure >450 PSI; stable at -10°C~50°C.

🔹 Material Safety: NSF 44 certified; suitable for direct contact with drinking water.

🔹 Dual-Layer Construction: PE liner + epoxy fiberglass shell for chemical resistance (pH 2–12).

🔹 Easy Integration: Standard 6-inch top & bottom flanges (ANSI B16.5 / GB/T 9119 compatible).

🔹 Lightweight & Durable: The total weight, including packaging, is about 135kg, easy to transport.

🔹 Long Service Life: 15+ years lifespan with minimal maintenance.

Accessories and base

✅ For accessories, a complete system should also include core components such as a water distributor, an automatic valve, and a central pipe, which are not included by default. If you require these components, please specify this when requesting a quote. The following is a diagram showing the installation locations of the accessories:

 

 

✅ For base, 4872 model FRP vessel uses a triangular base, FRP material.

 

 

How many 4872 FRP vessels can be packed in one container?

20GP	About 8pcs
40HG	About 16pcs

 

 

 

For an FRP storage tank, the amount of filter media it can hold is directly related to its capacity.
The capacity of the 4872 model is 1750L.
Therefore:

Filter Media Type	Loading Volume (kg)	Application
Quartz Sand	About 2,170 kg	Sediment & turbidity removal
Activated Carbon	About 560 kg	Chlorine & odor removal
Ion-Exchange Resin	About 980 kg	Hardness & scaling control
Manganese Sand	About 600 kg	Iron & manganese removal
