The 3672 FRP Vessel is relatively common in the pre-filtration stage and is ideal for use in medium to large-sized RO systems. It has sufficient capacity and performance for handling larger volumes of water flow. The 3672 model FRP pressure vessel is typically suitable for RO systems with a processing capacity between 300 and 500 cubic meters per day (79,500 and 132,000 gallons per day). Of course, this range is a guide only, and the actual vessel size will be affected by specific project needs, water treatment requirements, and expected water flow rates.
Key Features
| Parameter | Technical Details | User Pain Solved/Value Delivered |
|---|---|---|
| Capacity | 300-500m³/day (79,500-132,000 GPD) | Covers pre-filtration needs of medium-to-large RO systems, avoiding "overload" with small vessels or "waste" with large ones. |
| Operating Pressure | 150PSI (1.03MPa) | Stabilizes RO membrane operation, preventing pressure fluctuations from rupturing membranes (vs. industry avg. 120PSI). |
| Burst Pressure | 600PSI (4x operating pressure redundancy) | Withstands sudden pressure spikes without rupture, ensuring system safety (vs. 3x redundancy for traditional metal vessels). |
| Liner Material | Seamless one-piece PE (polyethylene) | Zero-weld design prevents leakage and contamination (vs. spliced liners prone to aging and cracking). |
| Outer Structure | Continuous fiberglass + high-strength epoxy resin | Pressure/impact resistant, lifespan ≥10 years (vs. 5 years for standard plastic vessels). |
| Bottom Base | PP round base or FRP-reinforced tripod base (optional) | Adapts to flat/sloped installations, preventing tipping (vs. standard round bases unstable on slopes). |
| Opening Design | 4" threaded opening (universal for ≤36" diameter) | Compatible with mainstream membrane element interfaces; custom sizes (e.g., 6" flange) available in 48 hours. |
| Threaded Insert | 30% glass-filled HDPP material | Threaded connections resist stripping, acid/alkali corrosion (vs. standard plastic inserts prone to aging and breaking). |

Application of FRP filter tank
Water Treatment
FRP filter tanks are extensively used in water treatment processes, including residential, commercial, and industrial applications. They are used for filtering and purifying water from various sources such as wells, rivers, lakes, and municipal supplies.
Reverse Osmosis (RO) Systems
FRP filter tanks are an integral part of RO systems. They are used as pressure vessels to house the RO membrane elements and other filtration media, allowing the removal of contaminants, salts, and impurities from water to produce high-quality purified water.
Industrial Filtration
FRP filter tanks are employed in industrial processes that require the filtration of liquids or gases. They are used in applications such as chemical processing, pharmaceutical manufacturing, food and beverage production, mining, and power generation.
Desalination Plants
FRP filter tanks are utilized in desalination plants to remove salt and other impurities from seawater or brackish water, making them suitable for drinking water or industrial purposes.
Wastewater Treatment
FRP filter tanks play a role in wastewater treatment systems, where they are used for the removal of suspended solids, organic matter, and other contaminants. They are employed in municipal wastewater treatment plants, industrial wastewater treatment facilities, and decentralized treatment systems.
